4 Position Rotary Switch

Perfect solution for my hood exhaust issue. Thermador Hood Exhaust fan switch panel gave out. Thermador no longer makes replacements parts for that model. Gutted all factory components and replaced with my own set up. This speed switch controls the exhaust motor and it is doing a good job. I wired the Thermador Motor to switch as noted; Black wire to H= High Speed / Blue wire to M= Medium Speed / Red wire to L= Low Speed. "B" on switch is for your black wire coming from your LINE (Hot) side. "C" becomes hot when you turn the switch on. Depending on your needs, C can be used or left alone.

This 4 position, 3 ON switch was utilized in the effort to retain all 3 fan speeds after the electronic control board began failing on our 10 year old cooler. Description for product is good. Quality of switch is good and appropriate for this price point. The control knob is sturdy and connections solid. The included female spade connectors are basic quality, but not trash, and were used in my efforts. There is a 5th terminal that passes power in all 3 ON positions. One could possibly use this terminal as power ON to the cooler pump when the fan is operating and have a one and done solution to get their cooler up and running. The toughest part of the installation was drilling and filing the mounting hole to final size to fit the switch correctly. (Picture note: The red switch operates the cool pump and the white switch is a push and hold ON switch from a clothes dryer door for the purge/drain pump.)

Works great but the connections would have been better if it was on a 90° angle

Easy install to replace a failed speed controller on my oscillating fan

It looks good and seems to do the trick

I already have this switch installed & it works great. In fact, as I write this review, I'm sitting in front of the high air output fan I used it on. Easy installation, good quality materials. I have no problem doing business with this seller again in the future.

The only complaint is the power wiring diagram that come with it. about 30 seconds with a meter and a guy can figure it out though. Basically the one extra terminal is switched to incoming power when the switch is in any of the 3 positions except off. When off this terminal is isolated. This could be used to power an indicator that the switch is no longer in the off position. Would buy again, great quality.

Easy installation. Sturdy metal construction. The set screw for the knob is too short & doesn't hold the switch nob on. I substituted my own machine screw as a replacement. Poor component matching for use needed regarding the screw.

Well built switch, locks firmly into each position. Would be nice to have a lock washer included. Works great as replacement switch on my leaf blower.

Perfect Fit for big square fan replacement/upgrade!

Excellent and works

I used this to fix my stove exhaust fan that has 3 speeds and it is very good quality
