SIEMENS 3SU1000-1CD10-0AA0 Mushroom Head Push Button 22 mm 60 mm Black Plastic Bezel

22 mm Mushroom-Head Push Button

This SIEMENS operator fits a standard 22 mm panel cut-out and provides a 60 mm black plastic mushroom head for emergency-stop or safety-interlock functions. It is built for industrial control panels that require a robust, momentary-action actuator with a low-voltage rating. The all-plastic construction keeps weight low while resisting oils and cleaning agents common in factory environments. Panel builders and maintenance engineers specify it when a visible, easy-to-actuate safety device is needed.

Replaces worn or non-compliant actuators

An upgrade is justified when an existing button shows cracked heads, faded colour or lost IP sealing after repeated wash-downs. The jump is worth it if the current installation lacks NEMA 4X or IP69K protection and the application now involves high-pressure or high-temperature cleaning. It also suits projects migrating to RoHS and WEEE compliant components without changing the panel layout. Operators needing maintained-action or illuminated heads must select a different operator type.

Limits of the 22 mm mounting standard

The 22 mm cut-out fixes the maximum head diameter and limits the contact-block stack height behind the panel. NEMA 1, 2, 3, 3R, 4, 4X and 12 ratings cover indoor and outdoor use but do not guarantee protection against all chemical exposures. IP66, IP67, IP69 and IP69K certify resistance to powerful water jets and steam cleaning, yet the plastic bezel may degrade under prolonged UV or aggressive solvent contact. Buyers who need metal bezels, larger heads or different voltage ratings must choose another series.
