Looking to put a new switch on my drill press after finding the current one is a momentary style switch.

I would like to do a foot operated switch.

The question-

Is there a specific designation for the switching action ie momentary vs click to on, click to off vs others?

Im looking at used ones on Ebay and usually its a picture of the mfg plate with a description like "yellow, works".

Deets:

120v operation
1PH
3/4 hp motor

Also, if I decide to go with a standard push button switch, do those follow the same class/designation or is it something else?

Thanks,

That A-B foot switch is pilot duty, it is not horsepower rated, in order to properly use it a contactor would be needed there are many who would use it as-is but it's not right.

The switch in the first post's image has a break capacity of 720 VA, which is not sufficient for the load.

Thanks for the replies.

I am aware of how the "deadman" or momentary switch works, but I would like a maintain style.

Many of that style are for light duty or contacts like Norcal mentioned.

But is there any industry designations like "class D" etc... that indicate how it operates?

Looks like the one from the photo is good for 6amps, where as my DP is 11.2amps.

Here you go:

You can probably find it for less money. I have a couple of them and they are of good quality.

There is no industry designation other than momentary or maintained contact. Any designation would most likely address the physical environment it's being used in. Dry location, wet location and any of the explosion proof classes.

My take is anything with a safety guard over top of it is a momentary dry contact version. It would actually make it dangerous to have the "maintained toggle" footpedal be relatively inaccessible with the safety guard.

I would never switch a motor load with it no matter what it says, just use a contactor.
