Welcome. My name is ***** ***** would be glad to assist.

Can you please clarify the situation?

You posted one switch and asked which one is compatible?

Are you just wanting one to replace a bad one and need the compatible one to replace it?

Thanks

replace bad one
Expert:  AssuredElectrical replied 1 year ago.

Ok, thanks for the information.

There is difficulty finding the specification on your fan unfortunately.

Have found several 2 speed switches, but cannot confirm your motors amperage.

Is there any way to get the motor nameplate information to see what the Amp draw is?

no fan in unfinished attic & I would have to walk on beams which is unsafe
Expert:  AssuredElectrical replied 1 year ago.

Ok, I can understand, we do it all the time, so it is second nature working in attics, but definitely tricky.

Wanted to verify the motors amperage for that reason to be sure it is a fit.

Not much luck in one similar to yours.

Expert:  AssuredElectrical replied 1 year ago.

I would just install a standard style toggle switch, instead of a fancy wall control.
All you need is a a Single Pole, Double Throw Center off switch.
Connect the common power and the 2 speeds just like the one you have now.
Up will be one speed, down the other speed and center is off.

These are rated at 15 amps and should serve well.
They can be found at most building supply, just may be in a different brand
