I have a couple of the Big Pushbutton Power Switch - https://www.pololu.com/product/2813, that I’d like to use it as a on/off + disable switch for an ESC for a RC-controlled model car. The ESC has no on/off slide switch.
Is there a combination of signals for the ON, OFF, and CTRL pins that will allow me to:
- default the power switch to the ON state once power is supplied
- be able to turn OFF the power switch via an external signal
- be able to turn ON the power switch again via an external signal
I’ve tried supplying a constant HIGH on ON, which fulfills 1) but it seems to override any control signal from the OFF/CTRL pins.
Another option is to provide a constant HIGH on CTRL, and supply the control signal via the OFF pin, but the product page seems to warn against it.
I’d appreciate any ideas, thanks!
