It's got a nice soft click and feels very nice when pressed. The LED is running off the motherboard which provides only 5V but is the perfect brightness. I've got it wired such that it just stays on when the computer is on, but can be wired to the HDD activity if preferred. Includes wiring instructions but for a computer power button it's wire a little differently than as they describe, since the LED is controlled by the motherboard, it doesn't need to be wired to switch. You just clip the wires on the old LED and switch from the computer and wire them up to the new switch and LED, it's a one-for-one connection. Just make sure to get the polarity right on the LED. The power button has no polarity. In my case the front panel is 3/4" inch thick, which meant I needed a short counterbore in the back to fit the nut. But the threads are quite long on the switch overall, but are just shy of about 5/8", so to fit in a 3/4" panel, you need a counterbore on the back. I have no complaints about this switch, the stainless steal looks sharp against the dark wood stain and the blue LED is the perfect brightness for this type of application. Not to mention the blue is basically the standard blue color popular on many electronics. So it will match anything else you've got if it's also blue. Can easily recommend! And don't skimp on the diameter, get the 19mm version, it's perfect for a computer power button. Anything smaller would not be as nice! ### ⭐⭐⭐⭐⭐ Finestkind *by D***C on Reviewed in the United States on September 9, 2021* These little beauties were exactly what I needed and they perform great. I also grabbed the connectors that made wiring a breeze. Documentation might have been better. Essentially it was little more than what you see in the pictures above.Will advise on wear in a few months. They are going outside in a salt air environment.Recommended 👍🏽 Helpful 👇🏽 ### ⭐ You take a chance when you buy *by M***. on Reviewed in the United States on September 25, 2017* Got a faulty switch. Led illumninates but switch just doesnt work. Swapped with one of my own switches to check if I had bad wiring, worked with that one. Used these switches in the past from different sellers, get faulty ones about once every three. Very frustrating when you expect an item to work and you have your project planned out only to receive faulty switch forcing you to put off the project. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.gr/products/65749650-ulincos-momentary-pushbutton-switch-u19c3-1no1nc-silver-stainless-steel-shell](https://www.desertcart.gr/products/65749650-ulincos-momentary-pushbutton-switch-u19c3-1no1nc-silver-stainless-steel-shell) --- *Product available on Desertcart Greece* *Store origin: GR* *Last updated: 2026-04-23*
