Push Button Station, 660V 10A 2 Position 1NO 1NC Momentary Emergency Stop Push Button Switch 40mm Red Mushroom Cap 2PCS

After building the enclosure for my CNC / Laser combination machine, I needed to extend the E-Stop to a realistic spot for stopping the machine in an emergency situation. The Nxtop Push Button Station works perfectly. Easy to wire and easy to mount. It works perfectly. If I hit the stop button the machine stops as expected. The only con I have found is it is made out of plastic. But for the money you can't go wrong. I would recommend this stop button for anyone with a small shop.

Very nice product, ended up having to modify the switch though, I need two separate NO closures but was not hard to do. A 350 MHZ remote control transmitter fits well in the case, I also moved the LED to the outside of the box for operation.

I purchased the Nxtop Push Button Station for its emergency stop functionality, and overall, I'm quite satisfied. The 660V 10A rating ensures it meets my safety requirements, and the momentary operation is responsive. However, one drawback is that the button cap can twist off a bit too easily. Despite this, the button itself functions reliably, offering peace of mind in emergency situations. If the cap were more secure, it would easily earn five stars.

Used these on several projects so far. Not sure I'd use them on 120VAC, but great for projects using low voltage DC as the control source. Well made, but definitely not indestructible quality. Happy with them for my needs.

For the most part it's a good product. I'm using the product for medium duty woodworking equipment. The only drawback is that the product is not offered with 2NC (Normally Closed) Momentary Switches (i.e. Contact Blocks). After a day of searching the internet I was able to track down a supplier that sold the appropriate NC switches. Most of my equipment is 220V single phase, but with two hot wires going to the motor I think it's safest to kill all of power going to the motor instead of just one leg especially if you're having to resort to using an Emergency Shutoff. It would be nice if Amazon would carry the CR37 (LAY37) Momentary Switches so it could be a one stop shop for these devices as they are pretty standard for just about in all of these types of imported electrical products. Reliability and construction seems to be pretty fair.

Very good!!!!

I purchased four of these switches to enhance safety of an electric train I built for my grandchildren. The switches allow the locomotive power to be shut-off from any car. They are intuitive and easy to activate, even by small children. I used the normally-closed option in my control circuit (which I consider slightly safer since a broken wire will stop the train), but the switches also have normally-open contacts if needed. They are also reasonably waterproof, although I don't leave them out in the weather full-time. Overall, they worked perfectly for me.

the switch latches in the "off" position when pressed. you must turn the button to re enable. overall quality was higher than the price.
