Hella Master Power Switch Probably the most popular Master Power Switch in the sport. Don't be fooled by the generic imitations, this is the true German-made Hella-brand switch. Red key is removable, insert and turn clockwise to turn on, turn counterclockwise and remove for off. Depending on your robot's design, you may want to consider cutting the red plastic key down and either threading in a small allen head bolt or just filing a slot for a flathead screwdriver, so you can turn your robot on and off with a simple twist of a tool. Then you won't have to worry about the big key getting knocked off in battle. -

Hella Contour Master Power Switch Need a bigger, heavy duty switch for your current-hungry bot? This big boy has a hard-to-miss large red knob with two positions, on and off (90 degrees to each other). The knob is non-removable when in these positions, so you don't need to fumble for special tools or a key. However, this switch features a unique setup where you can remove the knob in the OFF position, by pushing and twisting it 45 degrees CCW. This is the highest current-handling switch we carry. -

H2 Power Switch When you're on a budget, this marine battery switch does what you need. It's an "off-brand" version of the Hella switch, but works just the same, for less money. Red key is removable, insert and turn clockwise to turn on, turn counterclockwise and remove for off. Key has brass pin for solid switching interface. Mounting plate includes four holes for several mounting options. Extra keys not available, sorry. -

Heavy Duty 75 amp Push/Pull Switch 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! -
