The Elmark EL- Emergency Button (EL1-B174/1NC/IP44/Red) is a mushroom-head emergency stop switch designed for machine safety circuits. The large Ø40 red head is easy to strike in an emergency, and the latching action holds the switch in the actuated state until intentionally released by turning the head.

The 1NC (normally closed) contact opens the safety circuit when pressed, providing fail-safe stop signalling to contactors, PLC safety inputs and motor controls. The IP44-rated enclosure resists splashes and dust in industrial environments, and the body fits standard 6.8 x 6.8 x 5cm panel cutouts.
