You can't go wrong with a nice weatherproof metal pushbutton! Simply drill a 16mm hole (5/8" + 0.005") into any material up to 13mm (1/2") thick and you can fit these in place, there's even a rubber gasket to keep water out of the enclosure. On the front of the button is a flat metal actuator, surrounded by a plastic LED ring. On the back, there are 3 contacts for the button (common, normally-open and normally-closed) and 2 for the LED ring (+ and -). Connect 3 to 6V to the LED to have it light up nicely and there's a built-in resistor so no current limiting resistor is required! If you want to use this with a higher voltage, say 12V or 24V, simply add a 470-ohm resistor in series with the LED connection to keep the LED current at around 20mA.
The switch and LED are separated, so you could wire it to turn on when pressed or vice versa or whatever you wish!
