    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.

    - Continuous rating: 100 amps
    - Surge current: up to 1000 amps !
    - 3/8" copper terminals, silver-plated

    I used this switch as a master on-off for my RC tank. Its the only switch I found which can take high amps! Always works. Its a bit of a pain when the key falls out in the off position. Could put it on a retainer cord/cable I suppose - but switch works great

    Works great and feels like I couldn't break it if I tried, nothing else really needs to be said.

    This switch is SUPER durable and reliable. This is the REAL Hella, not a cheap knock-off like there are so many of. I've never broken one of these in any of my robots that have used them. I modify it usually by cutting the tall key housing down a bit, then mount using the two large holes through an aluminum bracket, leaving only the top of the key housing extending out the top of my robot. From there, I cut the handle of the key off, thread in a machine screw, add a ring terminal on a string, and I have just a nub of a key sticking out that I can turn on and off with a t-handle hex tool, and I won't lose the key when its off because it hangs by the string. Works for me! One thing you might want to do is support the back end somehow. I've seen other similar switches fall apart because of the inertia of impacts knocking the entire back end (with the terminals) off. I worry about this with Hella, but its never happened to me, so I play it safe and support the terminal end so hard hits don't knock it out of place.
