If anyone has done something similar I’d love to see it.
What you want to do is similar to wiring the
3-tab rocker switch in a fused IEC power inlet.
- It's a different application, but basicly the same idea.
Recoil power "+" (24v?) comes in on tab 8.
When the switch is in the "on" (closed) position recoil power is applied to the current-limiting resistor + lamp
and it goes out on tab 7 to the gun.
The possible difference for your setup is what you have connected to tab 6.
If you have a 24v recoil power supply and get a switch/lamp rated for 24v, daisy-chain recoil power "-" to tab 6 -- same as "Neutral" above.
If you have a 24v recoil power supply and get a switch/lamp rated for 12v like
this one, you'll need to add another current-limiting resistor between tab 6 and the recoil power "-" daisy-chain.
To calculate the value of that 2nd resistor, use an LED calculator like
this one.
- Power supply voltage (V): 24
- LED voltage drop (V): 12 (this is the voltage drop across the LED and current-limiting resistor inside the switch)
- LED current rating (mA): 20 (If the LED is too bright, you can reduce this to 15mA or less)
- Number of LEDs: 1
When you enter those values, you get a 620 ohm, 1/4 watt resistor. (15mA ==> 820 ohm)
- In this diagram, you would install it between the brass tab (tab 6) and the red wire.
- When you wire your cab, you should use standard wire colors -- red for DC+ and black for DC-.
