C4P momentary push-button

Post by lowrybt1 » Thu Apr 25, 2019 11:49 pm

I broke the momentary push-button switch on my C4 (installed left of the keyboard) for resetting they machine. Should the replacement be configured for momentary circuit "on" or momentary "off" ?

Thanks, Tom

You want an SPST normally open switch. The switch will close when you push it, and pull the RESET line low by connecting it to ground.
