This is primarily used with the MR/Hasbro Force FX sound boards. This works with sound boards/drivers that have separate leads for a latching switch. I have not tested it in a direct drive or resistored/buck puck set-up, and I do not recommend relying on this method to work in those situations.
This also has only been tested with this particular PCB
. I have not tested others. But I know this technique works and it has been proven many many times.
Wiring the PCB to your force FX sound board.
- The main negative of the PCB (that entire gold-circle back) goes to the main negative on the sound board (call this the "back" of the PCB).
- Take the little metal connection plate off and attach your momentary switch leads to those connection points (call this the "front" of the PCB).
- The two spots where the LED was attached will connect to your sound board main switch connections [sw(+) & sw(-)]. Sw(+) goes to the pad on the "back" of the PCB and sw(-) to the pad on the "front" of the PCB.
Good Luck! ;)
