Baomain Self-Locking Push Button Switch 3-Phase 30A 3.7KW, Industrial 3-Pole Heavy Duty,BMBSP-330/TBSP-330

Great switch. Works perfectly, not expensive, and doesn’t need a separate box. Simple wiring

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 switchother than that, it is perfect for smaller wire sizes.

I wish it would be larger but it works fine.

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.

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.

Entrega rapido

Purchased three for small (under 2 hp) wood working tools. First one broke before I even installed it. The “on” button simply wouldn’t depress. Began installing second one only to find not enough room for even 12 gauge SO cord (without stripping off the insulation). Not to mention no wire locks. Returned all three and took the shipping hit. Oh well...

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! *****
