Review on 💻 KNACRO 16mm Chassis Switch Metal Button Switch with 100CM Extension Cable - Blue LED for DIY Computer Switch & Restart Button by Josue Porter

I haven't used this to send "12V pulses" so the lack of functionality is probably my fault. The button I received wasn't sensitive enough and the connection wasn't good until it was pressed firmly. I was able to easily press the button above the hump without a trigger. Not comfortable enough for me because I can't expect everyone to press the button correctly. Maybe it's just my case, I disable Alarm IN on hikvision dvr for my doorbell and alerts, but it doesn't work perfectly. Can work well by passing 12V through it. Looks good, LED is bright enough at 5V.
