Fantastic Fan Alternative.

This little switch saved me over $100 by assembling my own multi-speed reversible roof vent fan.

Fan-tastic

I use this to control a 12 volt radiator fan that I use in my camper fan for both exhaust and cooling. I have bought this before and 4 years later they still work with no problems.

Great price.

Perfect for what I needed, cost effective and easy to use. Wish it came with a wiring diagram but the description has on and the board is labeled for + and - terminals for the input side.

Used to control 40mm fans in our travel trailer cupboards

I had condensation problem in the cupboards in our travel trailer during cold weather (15 degrees), even with the cupboard doors left open and a dehumidifier running. I installed a 2packs 40mm x 40mm x 10mm 4010 12V, covered by 40mm Black Finger Grill / Guard (Pack of 2) and controlled by RioRand 6V 12V 24V 28V 3A 80W DC Motor Speed Controller. This circulated enough air in the cabinets to stop the condensation problem, and is virtually silent when running. We can use the motor speed controller to turn the fans on/off or adjust the fan speed to the quietest/lowest speed that resolves the condensation problem.

Perfect

Put a roof fan vent and use this to control the fan in my cargo trailer. Works perfectly!!

Great controller, has not failed yet

Great controller, has not failed yet. The knob feels sturdy and has a nice click on and off. I personally screwed the wires into the terminals so I feel its perfectly safe. Many applications, great product.
