SPST Momentary yellow ring Illuminated switch
Will work with any box designed to hold 16mm switches and the recessed AV switch hole service. These will NOT work with the AVbezel as the shaft is not long enough to fit the nut on.
There is no internal resistor on these so you need to use the correct resistor in order to not fry the LED. The LED has a forward voltage of 2.1V and runs at 20mA. 4.8V would use a 150ohm 1/4 watt resistor, 6V would use a 220ohm 1/4 watt resistor. If you are not sure which to use please ask.
