Elizabeth R. ★★★★★

The 4.7K resistance works perfectly for dialing in my mill's speed, and the switch clicking at the off position is a nice safety touch. Took about ten minutes to wire up and it’s been running smooth ever since.

Ryan H. ★★★★★

The built-in switch that cuts off when you turn it fully counter-clockwise is a nice safety touch for my bench setup. Replaced the worn-out original and the knob has a good positive feel.

Charlotte ★★★★★

Installed this 4.7K pot on my micro mill and the switch action is nice and positive, no more guessing when it's fully off. Speed control is smooth across the whole range.
