1SFA619552R1071

The ABB 1SFA619552R1071 CE4K1-10R-11 Compact Emergency Stop Push Button is a reliable industrial safety control device designed for emergency-stop applications in electrical control panels, industrial machinery, and automation systems. It features a 40 mm red mushroom-head actuator, key-release mechanism, and one normally open plus one normally closed (1NO + 1NC) contact for emergency-stop control and auxiliary status signalling.

When pressed, the emergency-stop actuator remains latched in the activated position until manually released using the appropriate key. Unlike twist-release or pull-release versions, this model requires key-operated resetting, helping prevent unauthorized release. Its non-illuminated design, black plastic housing, and integrated contact elements support convenient installation in standard 22 mm panel openings.
