APIELE 19mm Momentary Push Button Switch On Off Stainless Steel with 12V LED Angel Eye Head for 19mm 3/4 Mounting Hole with Wire Socket Plug Self-Reset (Blue)

This switch works perfectly for a project to create a garage door switch with an indicator that the door was open. The switch and LED are independent. Some documentation things to note. The LED is rated for 12V AC/DC on the package. The instructions note DC. 12V is bright so I run it with 6.5VDC. The instructions have various wiring options but all have the switch wired in with the LED. Regardless, the LED and switch are independent. The LED does have a built in resistor (that’s why the 12v rating). Light looks good when lit. Switch is smooth momentary contact. Noiseless or almost noiseless. There’s a connector that comes with and plugs into the switch that makes wiring convenient and, I suppose, eases future wall plate removal (like to service the other switches in my application). Good quality.

This is a very well made switch and the LED ring was perfect for our outdoor application. We're using this to allow the public to turn on an audio system. The one thing I didn't like is that there was no way to prevent the switch from being turned by a vandal. However, the face sits quite close to a mounting plate so they'd need tools but they could twist and twist it and eventually rip out the wiring. The back of the face plate could have an optional key to prevent rotation. That said, I am very happy with the switch and it works well in a salt air environment.

Amazing switch! The 19mm size is definitely the way to go. We are building a van, and this will be our main switch. A couple of points. The click feel is excellent. The LED is INDEPENDENTLY wired. Which is beautiful because it becomes an indicator light that can be controlled separately. IE, a home assistant automation that can trigger illumination even if the button is not pushed. The LED draws about 6mA at 12v for those that need to calculate resistors. It WILL illuminate at 3.3v logic voltage, though not as bright as in 12v. I am using this with an ESP32 to create a smart automation. A simple 2N2222 transistor (and I used a 5k ohm resistor on the base - trigger signal from ESP32 3.3v GPIO) will illuminate the LED beautifully 12v. This will be our go-to switch. BTW, the yellow wire is useless (the NC). I can't imagine a switch when you click to disrupt, but it's there. The socket to attach the rear pins is very solid. Bottom line, the cool thing is that the LED is independent. I hope this helps to those that are curious.

Functions great and looks even better. I used this as a button on my motorcycle to open the gate at the end of the driveway. It even lights up at night so I can easily see it. I’m very happy with this purchase.

Works great for my "starter button" wired into my Ford Focus. LED light is very bright may be a bit of an overkill for night time use (there may be a way to dim the light). Plug socket is very secure, to much for my application in a tight space. I ended up soldering the wires on directly and adding some heat shrink tubing.

It works well as a replacement for the switch in my older but still nice computer case... the power switch was OK, but the actuator button broke. The hole happened to be exactly ¾", so it fit without mod. The lights match perfectly, but for it to fit I had to solder the wires rather than use the included connector. Don't forget the heat-shrink tubing, and I cut off the NC terminal. It was hitting the metal shell of the case and since the connector on the motherboard isn't polarized, I just happened to have it so the common terminal on the switch was high and the NO terminal ground. When I closed the front panel, the NC terminal was contacting the metal of the frame and it was like the button was stuck. The LED terminal is meant for 12V, but they must be using an active current limiter or something. I was worried that it wouldn't work with the 5V power LED terminal, but there is not too much difference between 5 and 12V. It's a really nice, soft blue glow that compares nicely to the HD Activity light. If you really want 12V, tap into a fan connector, but I didn't find it necessary. The switch itself has a nice snap to it, enough tactile feedback to tell when it actuates, and when I was testing the LED on my bench at work, I checked the contact resistance and it was within the noise floor on my bench. Highly recommended for this particular application.

These switches look really good and function good. They have a power and ground for the led ring, and a common, normally open, and normally closed for the switch simulair to a relay. I used these to control some air ride equipment on a truck. Best part about how these wire up is i put my valve on the common and keyed power to the normally open. That way when the botton is pushed it allows the ignition power to go to the valve. Then I ran the normally closed wires to another relay that the car alarm controls so that he can air out the truck through these switches from the alarm. Only thing that would make these switches better is if they could handle more amperage. They are only rated for 5 amps. So normally I'll use them just to control a relay. If you try to draw too much power through the switch it will fail.

I use this to reset the high idle to avoid stopping and restarting the engine on my 2022 F350 diesel.

Great action, with wiring instructions included, I've been using mine daily for 5 years and it still works.

It is well-designed with good quality. It is pricy for its class. The light inside might not be an LED, by reversing the applied power it still lights up (LED is polarity dependant). In some cases, it matters whether it is an LED or a bulb. UPDATES: It is an LED. Two LEDs in reverse/parallel directions so it turns on with any polarity (apparently with both DC & AC). As an electronic technologist, I rely on datasheets. If you are familiar with basic electronics, I would suggest putting a resistor (experiment with 150 to 330 ohms/ 1/2 watt) in series with the LED. direct 12v voltage put stress on LED (any LED) and might shorten its life, I haven't used it long enough to talk with certainty. I like it and recommend it as a good quality product.

Solid functioning switch. Fits well with the other switches on my dashboard. Easy install. Wired to open/close exhaust cutouts on my street rod.

good

Used for a line lock button
