22mm Stainless Steel Metal Latching Emergency Stop Push Button Switch with Connection Plug 12-220V 3A 1NO 1NC,MXU-DT-CT

I am a machine builder (In this case a laser cutter/etcher) and always look for the best parts, no matter how small or significant to the overall operation. That being said this very well made and finished metal switch was an excellent buy over the dime a dozen cheap looking/feeling plastic units. The over all build of these units are heavy and very robust with a very satisfying action and click to it's function. Best emergency stop switch I've seen yet! Exceptional switch and great seller that had it shipped to me quick even through the Covid shutdown that has hindered many others.

This switch appears to have a high build quality and works well. The price is very reasonable as well! Keep in mind, if you’re mounting it in an aluminum panel you will need to be certain that the stainless steel switch housing doesn’t directly contact the aluminum as this would result in corrosion from galvanic action between the two dissimilar metals. This is not a concern when mounting in a regular steel panel.

I have bought many plastic emergency stop switches for my cnc machines. I will not buy another one. This switch is rugged and beautifully anodized and chrome plated. The diameter of the hole for the switch is .866 not .125 comes with pigtail connector. Good quality product. Will purchase again/

These switches are VERY well built, I was amazed at its quality, considering that it sells for only about $20 (especially during current inflation). The E-stop switch is metal, feels very sturdy and it has operates very nicely/smoothly. I had to unfortunately return them because I was going to use these for a commercial automation project and the client wanted something bigger. These switches and mainly the box are quite small. The switch size itself really would be fine, they only need to make the box a bit bigger so that a user could put yellow "EMERGENCY STOP" decal around it. As they are sold right now, there is not much space to put any decal around the switch. In our commercial projects, there is always a safety requirement to put yellow decal around the red Estop switch. I would definitely buy these again for any personal projects or to use within our lab.

It seems well built but it takes almost no force to engage. Can easily be accidentally tripped. I would prefer it to have a stronger spring inside so that an accidental brush with it doesn’t engage it.

Started building a Lowrider V3 last winter, and finally returned to complete it. I nearly forgot to add an E-stop and this is a nice quality switch.

This button lasted approximately 20 clicks before it broke (thankfully it broke NO :). Maybe I just got a bad one, but it's not a great look. The main thing is that the aluminum button on top can't keep its orientation. After each time you push and then twist to unlock, the button rotates slightly within its housing, causing the label to be misaligned. This may not matter to you, but I want my label to face the correct way.

These are absolutely gorgeous: anodized aluminum buttons with a satisfying "clunk" when they're hit. Really pleased I went with these for the workshop. Remember, these are low-voltage only; if you're going to control mains power for big machines, you'll want these things to power a classic or solid-state relay or some other cut-out, rather than trying to pipe mains power through them.

sa semble bon léger fragile.........? ces a suivre.

Great product all aluminum head with a nice plastic body it comes with a wiring harness to make connections neat and easy. The push button is sturdy and is nice and compact. It looks really nice too.

Very well made, easy to install. It simply works.

First one had button shaft bent so the mushroom would seat on an angle (not sure how they did this). Second one was fine. Beware the push resistance on these is low so if you just graze it with your body it will activate. Also these are only single pole, either NC or NO so not the best option for ESTOP where you would want 2 NC contacts (one for contractor coil power and one for ESTOP condition to controller).

If you care, its got a much better feel and build quality than the all plastic ones.
