Rated up to 20 amps on 240V, should be good to go.

Thanks

A unisaw deserves a magnetic switch. If the saw looses power you want it to stay off if power is restored.

If your unisaw has a lvc it needs a mometary switch to latch the contactor coil.

I know less that nothing about wiring. I have avoided it ever since I almost electrocuted myself when I was 22. No kidding almost died. My uni currently just has an on off push button, which occasionally sticks. I bought a mag switch awhile back, and while I had an electrician doing some work for me I asked him to install it. He said the saw would have to be rewired. I didn't dispute what he said . My uni has a box on the back with all the connections. I'm not sure if all the saws have this or why . The switch I referenced looks exactly like mine minus the paddle.

I would say the saw is already wired for low voltage starting and the switch you show will work as you expect by only installing it.

The key to being safe with electricity: disconnect the power source *(unplug it) before attempting any work

The switch linked is a latching switch.

If the saw was has a lvc on it it will not work.

The delta switches that look like that many times momentary switches. On is NO and off is NC. They pass 24v to the coil of the contactor in the lvc box. The buttons will feel springy instead of latching on and the off unlatching the on button.

If the saw has no switches or lvc box you might be fine but with a bit more info I/we can help you.

I just dont want you to install a latching switch to a contactor.

Pm sent Mark.

This is the inside of a Delta momentary switch.

At least one of the reviews says it will not work with a magnetic switch.

LIL. You can either use that switch by itself as a cheap standalone start/stop switch, or you can find a momentary low voltage control station like the one Mike shows to wire in the LVC mag switch on the back of the saw. You can't use the switch in the link as the control station for the mag switch.

I have a similar switch on mine. From the Big Green Bear store. Pic is from July 2011, switch is at least 2 years older. I do have a big electric box on the back side, no idea what that's about. I put that switch on, replacing a similar switch I didn't like. Previous owner spilled Coca Cola on the motor and put in a 4 h.p. Leeson.
