Does a 60 Amp toggle switch exist?

Does a 60 Amp toggle switch exist?

Does a 60 Amp toggle switch exist?

(OP)
I'm building an electric-assist bicycle with a current power suppy of 24VDC @ 48A and an auxillery supply of 24VDC @ 17A. The power controller I have can accomadate up to 60A at the same voltage so there's room for improvement. To maintain this possiblity however, I need an On-Off-On toggle switch cappable of handling a constant 60Amps. I also require a keyed, On-Off switch that can handle the same current for safety/security reasons. I've searched many places on and off the internet and I can't seem to locate either type of switch.

Does anyone have a lead or link to a store that supplies/produces such toggle switches if such things exist?

They might exist, but I've never seen switches that big.

The traditional solution is DC Contactors (think Ford starter relays) controlled by regular switches.

Semantics problem. "Toggle" switches describe a small light duty device. Look for what are called "battery switches", used a lot in the marine industry. They are not "toggle" per se, they are usually rotary switches, but they will do what you want. You can also look into a 60A DC Circuit breaker, it will have that toggle style operation. A search for "DC Disconnect switch" will turn up a lot of hits as well, however because of the Solar industry you many end up flooded with stuff you don't want.

If there is a golf car dealer/repairman near you, stop by and take a look around.

Ahh, thank you all very much! These new keywords are very helpful indeed. I feel smarter now. Thanks again!

Look for battery disconnect switches at an industrial supply house. You can buy one from Caterpillar at Caterpillar prices, or get one for a lot less from an industrial supplier. These are small enough for a bicycle, key or handle operated (quarter turn) and will handle hundreds of amps. They are used as safety disconnect switches on diesel equipment and will handle starting currents on a large diesel engine.

For key operated switches find "Hencol lock & two keys" in the actuator field.
Note: these keys are widely available. Almost anyone who has operated cats or Cat loaders will have one on his key ring.
For an electronic relay, go to:
