Button Switch (Red/Green Emergency Stop)

Great quality product

Excellent

These estop buttons appear to be well made latching buttons that function normally. This brand offers the ability to use it in a NO or NC manner. That is important. The button is designed is 660v 10 amps and it can be used without a relay for low amps. 3d printers and other low amp DC applications will work very well. The math says you could use it with a 12 v circuit with 550 amps. However if you look at the wire size you should not attempt low voltage high amps. So to be safe I paired this button in its Normally Closed mode so that the button would provide power to a Normally Open relay of a machine I built, keeping the circuit energized. When the estop button is depressed, it will cut the control power to a 40 amp relay and the circuit will deenergize. The down side of my use is that it was designed to plug into an automotive relay installation and I needed to provide an enclosure and secure the relay to the case.

These 2 Emergency Stop Pushbuttons (commonly known as E-Stop's) are made from plastic and metal parts and they are for panel diameter holes of 22mm, the main housing (contact blocks and main collar block) is approximately 40mm long (traveling back into the panel/box) and approximately 28.8mm wide (left to right side) by approximately 39.7mm tall (the thickness-including up to the red separation release lever). These pushbuttons are lightweight, but I do not believe they are in no way light weight because of being cheaply made, because I think they are built solid and firm. The E-Stops have 1 Normally Open and 1 Normally Closed set of contacts, which can easily be changed if needed. As far as functionality is concerned, I think it functions well. I installed one into a small box and I have pressed it several times for testing purposes, and it has operated just as it was designed to. Resetting the E-Stop is as simple as giving the large front (Red) head of the button a clockwise twist and the E-Stop returns to its normal state. Also, there is 3 white direction arrows on the front for resetting reference showing the clockwise rotation for resetting it. So, for the installation the E-Stop it is as simple as drilling a 22mm hole in the location of your choosing and applying the functions of an Emergency Stop Pushbutton to your project/process. As far as the way the E-Stop looks, I think it looks a basic design, nothing fancy and it performs well. I will say that there's an included yellow ring that fits around the E-stop and it is marked with the words "EMERGENCY STOP" in black letters and it appears that the black letters are a bit faded and do not stand out. This is just my opinion, and this does not prevent the E-Stop from functioning, and it of course can still be read, it just doesn't stand-out as much as I would like it to. When it comes to the value, I can say that it's an average product for the price. At this point 2 of these E-Stops are approximately $30 USD which it could be said they are $15 USD each Which is a great Price for an E-Stop Pushbutton. But, after saying that I can also say there is other companies who also sell Emergency Stop Pushbuttons and they are practically all metal design and heavier built, but they also include a very heavy price tag. When it comes to selecting the best E-Stop for your project/process you have to decide what is the type of system it will be utilized in, and voltage and amperage ratings. Where will it be installed indoors/outdoors, in what type of environment. Ther is a large list of things to consider when choosing the right Emergency Stop Pushbutton, however this version is a decent mid-range option.

These are nicely made emergency stop switches for the price. Although plastic, they seem quite sturdy enough for my intended use as an emergency stop for a radio-controlled hillside mower I'm building. I'll use one and keep one as a spare. I'll use the NO pole for a motor grounding shutoff, and the NC as a power supply disconnect.These are modular operators and switches which can be easily disassembled and reassembled. Multiple switches can also be stacked onto one operator, so you can make a 4 pole switch from this set with 2 poles NO and two NC. You could conceivably stack more switch modules if you buy multiple pairs of this product or have another source for switches only. The switches are "snap action" through the use of springs and not dependent upon the speed of manual operation.

"Oh no! The 5.45 train is loaded with passengers and is going to collide with the slow tanker train crossing its track! What do we do now??" No worries, a quick press of the Big Red Button saves the day.As you might have guessed, this emergency button is being employed in my model railway as an "if all else fails, press this" button. It's bigger and offers a more reassuring way of stopping all rail activity than hunting out the little button on the controller that suffers from finger trouble in an emergency. Simple and effective and the benefits quickly outweigh the cost.As shown in the photo, it's a little marvel of engineering displayed inside its transparent box. A red lever switch returns the button to its "ready" condition after it has been pressed. There is a black screw collar to fit the mechanism behind a 7/8" panel hole.My application only runs at 13 V and about 3 A of current, which is well within its specification of up to 600 V at 10 A !

This review is for the "Emergency Stop Button Switch, 2pcs Red, Push Button Operation, 10A 660V, 2 Positions."I seldom trust budget switches, especially advertised for commercial or industrial use. However, this is a really well-made switch with generic interchangeable parts. Its latch strength is super strong, and an easy punch releases it from armed position. Contacts are perfect to power a master relay, which I strongly advise this switch is used to engage.Fit is precicely the same as others of same design- a drop-in replacement. I use these in fiber and CO2 lasers. I like to replace them every so often just to ensure the contacts don't become sticky.Worthy of recommendation imo. Great value and great functionality.
