Pellejons Posted April 9, 2016 Share Posted April 9, 2016 I would like to have a switch that sends an activation signal (like the laser trip beam) when power is LOST. Like an inverted electromagnetical relay that is open when power is applied and then closes by spring pressure if power is lost. And i don't mean a switch that inverts the on/off switch so it looks like it's off when it's on just to be clear. I know many don't care about that stuff but I like to make all sorts of traps and funny things with the electrical equipment from the workshop. It would also be nice with an explosive charge that's activated by electrical power. Link to comment Share on other sites More sharing options...
