Added Switch for wrapper machine
Worked great for my pallet wrapper

Good switch for any stationary tool or electrical power need
Installed for pump switch. Works perfect. And the switch stays locked in either on or off position. Dislike ground capability. No place to hide wire inside box. For 240, it’s a 3 wire box, so ground is outside. If used for 110, you can use all three poles. Just remember, BLACK (RED 240v) are the LOAD WIRE. WHITE is NUTRAL. Make sure all connections are tight and works great.

Perfect For Smaller Wires
Love this thing! simple but good design and very nice look and fit-up, only issue is there isn't a lot of room inside for wires, not good for super thick cables, worked great with 14awg. Probably going to last a long time due to durability.

Easy replacement
For the price, it was an easy choice, and was easy to replace.

Great on off 3 wire push button switch for smaller gauge wire size.
This on-off switch is what I wanted, but I have eight gauge wire wrapped in black round rubber, so it is too big for this switch other than that, it is perfect for smaller wire sizes.

Works exactly as intended
My old clunky air compressor had no switch so I was constantly needing to plug and unplug the motor. The outlet is not very happy with unplugging it while the motor is running. This switch fixed everything. Love it.

Works Great
Excellent switch. UPDATE: I had a problem with the item and notified the seller who promptly replied. A few hours later I was notified that a replacement was going to shipped to me and would arrive in a few days. Excellent customer service! *****

Great switch for my hydraulic forging press build. It runs a 5 HP 220 Volts motor with 30 Amps breaker and 10/3 wire. The wire fits snugly and could not be bigger, as it would not fit. It's working fine but was a bit hard to wire as I needed to fit all 3 wires (white hot, black hot and green ground) at same time in their respective connectors under the screws. Not easy but I managed to do it. My motor runs great and I am happy with this switch. Great bang for buck. I will add a scelant to the hole where the wire goes through on top because there is a gap for dust to get in, which could cause shortcut. See last picture to better understand.

Arrived on time. Installed it in my old radial arm saw as the original inoperable switch was listed as obsolete and no longer carried by the saw manufacturer. I had to secure the new switch to a small metal plate using the mounting holes in the base. The two apertures at either end of the new switch made the wiring easy. It works great and I have my old saw operational again. Well made. Great value for the price.

I'm using this switch for 220v 20amp pressure washer and so far it is working good, easy to install I would buy again.

Works well, quality seems lower. Plastic seems cheap and brittle if impacted. Price is right
