EJ12 — 12 mm Economy Short-Body Metal Push Button Switch

EJ12 is the economy short-body option in the 12 mm metal range: a domed SUS304/316 stainless head on a shallow body, with one normally open (1NO) contact. It comes in two terminal styles so the same switch fits either a circuit board or point-to-point wiring — PCB solder pins (EJ12-231P) or screw terminals (EJ12-231A). Both are sealed to IP65.
