The three rocker switches we will be going over are our RC rectangular switch, our RC round switch with a light, and our RC 4 position joystick. There are two rocker switch varieties, momentary and non-momentary or latching and non latching. The momentary non latching ones must be held down to maintain the connection, while the non-momentary latching ones are just pressed and stay in place until you press again.

We will be using the momentary non latching switches for this Instructable. The rectangle rocker switch is the simplest of the three switches, so we'll cover it first. It is a double pole, double throw DPDT switch with a neutral position. The two center connections T2 and T5 are the common connections.

When you press the switch in one direction, you connect T2 to T1 and T5 to T4. Pressing the switch in the other direction connects T2 to T3 and T5 to T6. We can use this to switch the polarity on the actuator, causing it to extend and retract. Connect the pins as follows, see the picture for a wiring diagram:. Pressing the switch to the other side gives V across the actuator causing it to retract.

When the switch is in the neutral position the actuator isn't connected to any voltage so it stays still. The round rocker switch has different switches inside of it then the rectangle rocker switch.

It also has a 12V LED that you can wire as a status indicator. This switch has a lower current limit then our rectangular rocker switch. If you are going to be controlling more than 2A you should connect this switch through a relay. Click here to see more information on the 12V relay. By following the wiring diagram above the actuator will move one direction when the switch is not pressed and the other direction when it is pressed.

You can switch directions by swapping the actuator connections. With no relay, wire the switch as follows: see wiring diagram for Uni Directional Control.

To include a relay, wire the switch as follows: see wiring diagram for Relay Control and 12V Relay.How to wire a rocker switch to a circuit is a common query many people have. Do you want to control one light from two switches? I hope this helps you with your next LED lighting project, make sure to check out the great variety of switchesrocker switchestoggle switches we have to offer.

Do you carry something like this? Relay available here: 5 Pin 40 Amp Relay. I need a couple of rocker switches, three-pin and two-pin. On a three-pin switch, can I use the two of the pins 2 and 3 without the ground as if it were a two-pole? Thank you. I wired up a led spst round rocker switch like the one above and it works just fine for turning on and off the accessory which has its own ground cable going to ground. However, as soon as I connect the ground wire from the rocker switch to ground, the led light comes on and stays on regardless if the switch is in the on or off position.

Do you know why that might be? Is the switch bad or shorted somewhere?

How To Wire 12 Volt LED Lights In Your Camper Van Conversion

Is it possible to dim the indicator light,? To dim an LED, you can use a resistoror a series of resistors. Or you could even use an LED dimmer. To have the light only turn on when your headlights are turned on, you need to find a power source that is only on when the headlights are on. This could mean tapping into a certain fuse, or tapping into the headlight wire.

The boat was inoperable at night, because the blazing blue switches messed up night vision and obscured everything in front of the boat along with a very poorly placed anchor light, incorrectly wired so it comes on with the running lights — a separate problem scheduled for my next fix. I can run a common ground to all 9 switches, and pass that ground through a rotary pot. I would also want the brightness to stay relatively constant at the set level, regardless of how many switches are illuminated.

Do you have any recommendations for dimming LED illuminated switches? Having trouble getting the first switch to light up. The accessory that switch 2 puts on is a car line lock. Thanks, Wim. Hi, I bought a some switches which have an led indicator light in them. Can I do that? Hook up only power and ground to the switch.A relay is essentially a switch that is operated electrically rather than mechanically.

Although there are various relay designs, the ones most commonly found in low voltage auto and marine applications are electro-mechanical relays that work by activating an electromagnet to pull a set of contacts to make or break a circuit. These are used extensively throughout vehicle electrical systems. This is the most common reason and useful where an in-line switch or the existing circuit does not have the capacity to handle the current required.

For example, if you wanted to fit some high power work lights that come on with the headlights but there is a risk that they would exceed the capacity of the existing loom. High current capacity wiring and switches cost more than lower current capacity versions, so by using relays the requirement for the more expensive components is minimised.

You can use a single input from one part of an electrical system e. Although these logical functions have now been superseded by electronic modules for OEM designs, it can still be useful, fun and often more cost effective to use relays to perform them for some after-market projects particularly where you have a bespoke application.

Note: In this article we are going to focus on ISO mini or 'standard' relays which have a 1" cube body and are the most commonly used in vehicle electrical systems.

How To Wire 12 Volt LED Lights In Your Camper Van Conversion

A copper coil around an iron core the electromagnet is held in a frame or 'yoke' from which an armature is hinged. One end of the armature is connected to a tension spring which pulls the other end of the armature up.

This is the relay in its de-energised state or 'at rest' with no voltage applied. The braided bonding strap provides a good electrical connection between the armature and yolk, rather than relying on contact between the armature pivot point alone. The coil and contact or contacts are then connected to various terminals on the outside of the relay body.

When the coil is supplied with voltage a magnetic field is generated around it which pulls the hinged armature down onto the contact. This completes the 'high' current circuit between the terminals and the relay is said to be energised. When voltage is removed from the coil terminal the spring pulls the armature back into it's 'at rest' position and breaks the circuit between the terminals. So by applying or removing power to the coil the low current circuit we switch the high current circuit on or off.

The coil circuit simply switches the high current circuit on. The following simplified circuit diagram is often used to easily understand how a relay operates:. Normally Open relays are the more common type. These have two contacts connected to a common terminal. This is based on standard switch terminology.

The terminals on the outside of a 4 or 5 pin mini relay are marked with numbers as shown below:. The automotive ISO mini relays we have been looking at above are typically available in two types of pin layout designated Type A and Type B layouts. These layouts are shown on the two 5-pin relays below pin 87a not present on 4 pin relays :. You will notice that on the Type B layout pins 86 and 30 are swapped over compared with the Type A layout.

The Type B layout is arguably easier to work with as the connected terminals are in-line, making the wiring easier to visualise.

If you need to replace a relay make sure you use one with the same terminal layout as it is easy to overlook if you're not aware of the difference. The terminal widths used on 4 and 5 pin relays are almost always 6. The 9.

Relays can look very similar from the outside so they normally have the circuit schematic, voltage rating, current rating and terminal numbers marked on the body to identify them.

This shows the basic internal circuits including any diodes, resistors etc. The operating voltage of the coil and high current circuits. Typically 12V for passenger vehicles and small craft but also available in 6V for older vehicles and 24V for commercial applications both auto and marine.

This is the current carrying capacity of the high current circuit s and is normally between 25A and 40A, however it is sometimes shown as a dual rating on changeover relays e. Tip: Knowing the coil resistance is useful when testing the relay for a fault with a multi-meter. A very high resistance o r open circuit reading can indicate a damaged coil.

Terminal 87 is linked to pin number 87b, giving double outputs from the single NO contact.Wiring Diagram Sample.

Check out the MAG speed control on this pageI think it's exactly what you're looking for.

I have used it with great results. The way it's wired, you press one switch for forward, the other for reverse. It is the same wiring as Steve's drawing, but with a little bit more detail.

Rick's design requires you to press both switches to reverse direction and there is no 'off' position. Answer 7 years ago. I would be inclined to put the rheostat between one of the motor leads and the switch 1or between a battery lead and the first switch 2. Anywhere else, and I don't think it will control the speed for both directions. I dont know of a way to do it without a micro controller like the arduino. Im sure there is a way.

I would post a new question, there are many members with much more experience than me and they should be able to point you in the right direction. Answer 8 years ago. This is the same diagram as used for house lighting where you have stairs and want to turn the light on or off from either the top or the bottom of the stairs.

It works fine and will work in this situation as long as there is a common terminal on the microswitches. Yours also requires that both switches be pressed for one direction, and both diagrams have the off position where you've only pressed one of 'em. The motor is off when both switches are in the same state pressed or releasedthe motor is on when the switches are in different states. With both switches open, negative is connected to both terminals of the motor thus, the motor is off.


Press one of the switches, positive is connected to that pole of the motor remember the negative is still connected to the other pole, the motor spins one way. Press both switches, positive is applied to both motor terminals, and the motor is off. Rick's requires both switches to be pressed to change directions, and one pressed to stop. Steve's is the same as my diagram. The truth-table is the same for all of them, you've not seen that yet.
