As part of my tig inverter, the timing and power switching circuitry would be about 5 feet away from where the controls are. There will be3 controls: power on/off, variable capacitor and potentiometer.
I would like to use some shielded Cat6 cable for all three controls.
I would like to switch DC power on and off, using the switch on the front panel of the welder, simply as a gate input to some electronic switch that would power up the rest of the timing/gate driver circuit. I estimate the power draw of this circuit to be about 1A at most at 15 VDC.
So... Is there some good remote switch, preferably in a DIP package, that would enable me to switch DC power on and off, using same DC power as signal. Thanks.i
