I apologize in advance because I am mostly electronic illiterate.
I am trying to build a set of inline on/off switches for remote control of 3 microphones using 3 illuminated push button latching DPDT 2NO2NC switches the LED in the switch is rated up to 24v 15mA. I'll be powering the switch LED with an AC 100-240v to DC 12v 3A power supply adapter what I need to know is what size resistor needs to be run in series from the adapter to each of the switches LED from my calculations I think I need 700ohm 36watt. Is this right if so I dont have room for a 7 in long wire wound resistor much less 3 of them.
Also there will not be power going to the microphone from the power supply. Any help would be appreciated and if this is absurd and would never work then harsh criticism is welcomed thanks in advance
