mxuteuk Momentary Start Stop Switch Push Button + 1NC Red Mushroom Latching Emergency e Stop Switch Station Box Pushbutton Switch HZ-JTSS

This worked great. I used this together with a relay that I also order from Amazon … https://www.amazon.com/dp/B09H6RP3ZL?ref=ppx_yo2ov_dt_b_product_details&th=1.Someone in another review asked about a diagram. This is a schematic called a ladder diagram. There are websites that explain how to read the diagram if you have not seen a ladder diagram before. I used this to control my router table. I used this button box, the DPDT 110VAC relay linked above, a power cable, a standard duplex outlet, outlet box and plate. How it works is, when you press the start button, the relay coil is energised. This closes the contact in parallel with the start button. It also closes the second contact that supplies power to the output. The circuit stays on until the stop or emergency stop button is pressed. In the event of a power failure, the circuit returns to a off state. I’ve added a point-to-point wiring diagram. Because of my electrical current needs, the relay I used is too large to fit in the button box.

On the opposite side of the machine tool operation panel, this control box is installed, with emergency stop switch, reset button and start button, so that the operator does not need to run back and forth to press the button. The switch is flexible and has good contact.

Its tricky to remove the buttons, but they do come apart with a flat head screw driver as a small pry bar. good action, removeable contact blocks and good printing on the buttons. I took the buttons out of the box and used them in a metal enclosure, but for the price was a deal for three good buttons.

The weather seal is iffy, and locking collars inside were loose. Overall not the worst thing ever, considering the price.

I'm no electrician but I can wire if I had the wiring diagram....

I was looking for a start/stop/estop box to control the VFD on our lathe. This looked to fit the part. As far as the buttons go it worked fine but I wanted to mount it vertically instead of the horizontal layout that is default. I expected to be able to turn the buttons 90 degrees to make the lettering line up but that is not possible with these momentary buttons. I ended up modifying the stop button to allow me to turn start and stop. Otherwise it worked great.

Great switch. Nice box. Sturdy. I fastened mine to a wall by drilling holes in the back.

A pretty simple device, but still, a wiring diagram would have been nice - more as a security blanket for those of us that don't install something like this every day than anything else. So far, its been really reliable. Captive screws would have been nice.
