Review on ✨ 13FL Electromagnetic Aluminum Indicator - Mxuteuk, 1 Inch by Jeffrey Gallagher

Purchased. Received in very good condition. I like the LED that lights up when the coil is on. Did a quick test to see if the speed switches from one 120v power supply to another. My computer can survive without rebooting during the switch. My computer's power supply does not conform to the EPS1U standard, which requires a minimum delay time of 17 milliseconds (I don't know how long the delay actually is). I don't know how fast this rendition can play, but luckily it's fast enough to complete the Switch transfer before my computer's performance lag stops. I made some switching attempts. Everything so far without problems. Happy with it for now. Decided to buy another pair to complement my failed 3-dpdt relay auto switch. Update: I've finished my automatic switch that can switch between two power supplies, with a switch to control both power supplies to be used as preferred when both have power. We've been using it for a few months now with no problems. The built-in 10A fuse holder (no fuse) has only blown once, but the relay is fine. (I probably shouldn't be using the built in plastic fuse holder to hold a 10A fuse on a 120V supply. I switched to using just a 5A fuse and kept the current between 2A and 3A limited Looks good I bought another pair to build two simple signalers for my TV and other electronics Looks good.
