This is a very popular power switch for robots in many weight classes. It can handle a continuous 75 amps easily, and has been battle-tested by many robots.

The only complaint about this particular switch is that if your robot is hit hard enough from just the right angle, the switch can be clicked off from the inertia. We recommend unscrewing the chrome knob, which acts as a counterweight to push the switch off during battle. Some builders have also modified this switch through a double-mounting face, so that they twist the knob onto the threaded plunger to click it on, then there is no way to click it off without twisting back the other way.In any case, this is a great solution for a master power switch in combat robots!
