Review on 5PCS 16Mm Latching Push Button Switch Angel Eye Ring LED DC 12V/24V Waterproof Metal Pushbutton Switches 1NO1NC SPST ON/Off Toggle Switch Self-Locking Round Switch For Marine Car RV Truck Boat (Red) by Jason Staggs

They work great, I used them to make front high beam headlights 'always on' on my 70's car but I can still turn them off. A glowing indicator shows me the status. The instructions go against common standards, showing the battery as a load device and causing me to miswire the first switch I set up. I had to look closely at the drawing to see what they were doing. The usual standard for wiring drawings is that the battery is the power source and the light bulb is usually the load device. I have no idea what it's about.
