These are large SPDT (both normally open and normally closed contacts) LED lit metal flush-style push buttons, each item you buy is one button, you need to choose the style you want, I have the below.
If the button style you want is out of stock, and you can make do with a standard single contact (SPST) button, check this listing instead.
Each button is lit by LED, the voltage for the LED without any external resistor, 3-6v. If you want to use a 10-15v supply (eg in a car) then simply putting a couple of 1k resistors in series with the LED should work nicely – if you ask me I can include suitable 1k resistors for you.
The switch does not control the LED, that is up to you to do how you want to do it.
There are 5 terminals on the back, see the pinout diagram in the images.
Hole size 19mm should do it, maybe 19.5, the bezel is approx 22mm diameter.
I do not have current or voltage specifications, typically this sort of switch you keep to 12v or so max (remember the LED is 6v max) and use for low current maybe 1 or 2A at the very most (really you would use this to switch a relay or transistor not the main current).
“Off” Colour Note
Some batches of these appear clear/white when off, some batches appear with the colour when off. If this matters to you, ask!
