Switch Rating

16mm billet buttons are rated @ 3 AMP.

All other billet buttons are rated @ 5 AMP. But…

We do not recommend running anything directly from the button that pull any significant draw; even if they are rated for 3 to 5 amps it is best for them to be wired in pair with a relay. It is just common sense to use a relay in most automotive use anyway unless you are switching an analog input on your ECU. But don’t worry, if you happen to burn the contact in your buttons we do sell replacement micro switch here!

Using a relay is also good at preventing back feed over-current from a switched off circuit that could burn the LED (not covered under Warranty), if you have wired it in parrallel with your circuit. Ie  a switched off inductive load (like a Fan motor) can often reach 5-10x the nominal voltage for a really short period of time and that can burn out the LED. We do sell neat fused relay under the Misc Parts categories as well as Solid State Relay.

Basic wiring skill is required to install these button; if you install a “Two Step” etched billet button on your horn, chance are good your horn will honk when you press it!

Button Switch Action

Almost all button are available Momentary and Latching. For those wondering what this mean, a latching button act like a toggle switch; you press it in and it “Clicks on” and when you press it again it “Clicks off”. Momentary buttons on the other end are only active when you hold them pushed. If you are not familiar with Normally Open (NO) and Normally Closed (NC) switch I suggest that you read a bit on it. If you have any question we will be happy to answer them.

LED Wiring

Single color LED are not polarity sensitive. Because the LED have their own pin on the button you can have full control over them. It is easy to wire them so they light on;

  • When you press or activate the button
  • With your Parking Light
  • Controlled by a programmable ECU
  • A combination of all of the above

If you are having the LED light when you press the button, make sure you are connected in parralel so you don’t have too much current going through it. LED can only take a few miliamps before they burn. When in doubt, use a relay.

RGB LED button are polarity sensitive. The 19, 22 and 25mm buttons with an RGB Led have a Common Anode. That means they share a common Positive (+12vdc) lead and you must ground each color pin you want to light. The wire color on the pigtail will match the buttons LED color pin. You can use them for a single color or make your combination of color. RGB led can not be driven by a LED controller and display the full range of color.

Additional Micro Switch

The 25 and 30mm buttons have provision for a second micro switch. If you need an additional micro switch for your application, they can be had here. The 25mm buttons use a SPDT micro switch while the 30mm buttons are DPDT.
