  • Great for electromagnetic starter, relay, Horn Button Switch, PC Power Switch or any circuit controls
  • Metal shell,100% brand new and high quality,mechanical life for 500,000 cycles


What You Get:
1 * pushbutton switch
1 * resistor (680Ω)
1 * wiring instruction
What's the Pushbutton Switch:
This is a perfect choice if you are in need of a rugged push button! These metal push buttons are a very tough, small, panel-mount momentary switch with an illuminated blue LED ring. It is a SPST with 19mm threading and 1mm pitch. These momentary buttons are rated up to 3A and 250VAC while the LED is rated for 1.8-2.8V.
What's the Momentary Switch:
Momentary switch, normally open, remain in ON state as long as being pressed.
What's the Momentary Switch Used for:
Most often momentary switches are used for circuits control in electromagnetic starter, stuff like relay, Horn Button Switch, PC Power Switch or any circuit controls.
What's Note:
-These switches come with a rubber O-ring which makes them splash resistant but they can NOT be submerged in the water.
-The switch is rated up to 3A/250VAC, but the LED is rated for 1.8-2.8V, if you want the switch and LED to work under 12V, you need to add the resistor.

This is a really nice illuminated push button (momenary). I'm happy with it.Of note:* As others have mentioned, the wiring can be a little tricky depending on the effect you want. Just play around with it, that's the fun part. It comes with a wiring diagram.* The mounting depth is surprisingly deep, take that into account. It didn't sit flush with the first case I mounted it in. Fortunately I had a slightly larger one available.* Button is rugged and has a high quality, robust feel to it and a great tactile response.* People asked about Voltage ratings. Vendor claims 240v. I ran a 120v circuit with it with absolutely no issues or concerns. Currently it is handling a 12v circuit and I feel it is suitably overrated for that purpose.Inexpensive, fast arrival, and good quality. I plan on buying a couple more once the blue version becomes available again.

it's what it says it is. works great, easy to wire because of the diagrams in the images of the product page. i hope the resupply again soon, as i bought the last one without international shipping. good stuff, and quality hardware.

Fantastic switch. When it arrived I could tell the solid metal feel meant quality. What was even better is the customer service of the seller. When I was asked my opinion I mentioned that I accidentally burned out the LED in the switch because I did not put a transistor in my circuit (Completely my fault). Without delay I had a brand new switch in my mailbox.THANK YOU SO MUCH! This was such a great show of generosity to send me a new switch. I will order again from you 10/10.

The switch arrived very quickly and installed very easily. It works great and looks good in my dash too! I love the light up feature so I can easily see it at night when I need to use the air horn it is controlling.

This button worked perfectly as a toggle for my front gate. I (temporarily) wired it to the motor's 24V source, with the positive connected to a 2.2k resistor, and the left/right terminals wired to the motor's button inputs. I'll be getting two stainless ones that should look pretty slick on a plain white wall plate, and this one will be saved for some future project down the line.While it does look great, mine did come with some scuff marks that I wasn't able to get off, but unless you're looking at it closely, you would never notice.

Used this to create a new dome light in a an old Pontiac Fiero. These look amazing! This upgrade make my little project look absolutely cool. Also they are really functional because I have it light up red when the car is running so you can see them even when its dark. These are great. Very happy with these.

One mine didn't come with so called resistor and two the pins on the back side where not made big enough to do anything with so I give it a zero if I could
