Horn button on the ute is sticking, or you're wiring a starter-motor trigger that's going to see rain, mud, and the occasional hose-down. This is the switch that shrugs all of it off. 30mm diameter, plastic housing with a protective rubber cap that seals out water and grit. Cut a 22mm hole, drop it in, screw the terminals tight — you're done. 5A DC rating handles horn circuits and low-voltage starter activation without drama. Momentary action means the circuit only runs while your finger's on it. No accidental full-throttle situations
