Some people are getting confused with the sizes of the buttons. I am going to fill everyone in on what is best for you, so you make the right decision when it comes time to hit the buy button.
The sizes represent the hole sizes needed to be made for the install of the buttons and you need to add around 3-4mm for the total size of the face of the button. The 19mm buttons are a small button and can be difficult to push if you are wearing gloves. If the room is available, I recommend the 22mm buttons as they are the best all round size of button for ease of push. The 28mm buttons are more for the people who like having a bigger start button to push that matches the 22mm buttons.
Just remember that all the buttons have a 5amp rating and will require a relay to run in conjunction with them for the higher draw accessories. Most cars already have relays installed for the factory switches between the higher draw accessories. For example thermo fans, fuel pump etc. I also have a 6 months warranty for the buttons but it does not cover incorrect wiring. So please, if you are unsure about anything just ask me or a friend that is good with auto electrics. I do now offer replacement micro switches for the 22mm and the 28mm billet buttons if you accidentally burn the switch out they can be found here.
We get asked all the time about wiring diagrams for the buttons so I thought it's about time I put something up to help everyone out to prevent incorrect wiring. This is just a simple wiring diagram from the rear of the business cards that everyone will now receive with their buttons.
IMPORTANT!! PLEASE READ The LED has a current rating of 20mA so if you are wiring the LED into the circuit so it will come on when button is pushed you must use a relay in the circuit to avoid current running through the LED otherwise it can burn out!
19mm Buttons: The 'RED' & 'BLACK' wires are for the LED, you can reverse the polarity on these and it will not damage the LED. The 'WHITE' wire (common) and the two 'GREEN' wires (normally open, normally closed) are the switching wires. Simply, the 'WHITE' wire (common) and the middle 'GREEN' wire (normally open) are the two wires you will need to use as the switching wires. If you want to wire the LED to come on when the button is pushed simply wire the LED into the switching circuit.
22mm & 28mm Buttons: The 'RED' & 'BLACK' wires are for the LED, you can reverse the polarity on these and it will not damage the LED. The 'GREEN' wires (normally open) are the main switching wires you will need to use, the 'WHITE' wires (normally closed) are there if you want to switch between circuits. I recommend running a 5 pin relay if you are wanting to switch between circuits, for example high and low beam. If you want to wire the LED to come on when the button is pushed simply wire the LED into the switching circuit.
