mxuteuk 2NC 22mm Emergency Stop Push Button Switch Red Mushroom Equipment e Stop Shut Off Switch AC 660V 10A HB2-BS544

Works as it should. Seems fairly robust

Item works exactly as advertised. Durable as needs to be and simple to install.

Absolutely zero paperwork. I ordered the NC version to use as the Emergency Stop button next to my breaker box for a 30kW self start ATS connected Propane Generator I self installed just so there is something close by to shut it down without having to run outside as it must be 30ft from the house. DO NOT undo the screw on the end, it takes a lot of twisting the spring and pushing and turning it to get it back reassembled correctly so it works again. To get off the switch part push and twist the silver round portion. It needs a 3/4in round hole. Works well but took off 1 star for no documentation. Manufacturer - how about supplying a simple piece of paper showing how to take it apart and the hole size?

great switch for rapid shutdown PV system. thats my second

Worked exactly as the one it replaced. Used on semi-automatic cold saw for cutting tubing.

Failed before we even finished testing. Would not stay engaged would not twist properly. Seems like cheap internals

Considering this was $80 cheaper than at my local electric store and the structure is made of metal I’d say it was well worth the money.Note: to split it apart simply loosen the hold down screws, don’t be like me and remove the center screw which holds the spring in the button.

Crisp operation, has done well in several applications I’ve used it on for over a year now.
