Puppy Power Switch - Fail On Screw Switch

Reliable Power for Combat Robots 3 pounds and up!

Designed by SAGC, the team behind Golden Dumpster-winning bot Chainsaw Kitty, the Puppy is a unique style of screw switch with reliability as the main priority.
The electrical connection is maintained entirely by springs compressing copper contacts rather than screw threads. The screw is only used to pull the contacts apart to turn the switch OFF, but even if the threads strip, the switch can stay powered ON, significantly reducing the chances of a fight lost due to a faulty switch.
