Extended Green Push Button
This SIEMENS 3SU1051-0BB40-0AA0 operator provides a 22 mm extended metal head for panel mounting. Momentary action returns the contact to its default state when released. The green colour identifies the function at a glance. Rated IP66, IP67, IP69 and IP69K for harsh environments.
Industrial Control Panels
Suits panels that need a durable, illuminated-ready momentary input with high ingress protection. The metal bezel and head resist mechanical abuse in manufacturing or process settings. Not for applications requiring maintained latching action or a different colour code. Buyers needing a key-operated or mushroom-head operator should look elsewhere.
22 mm Mounting Diameter
The cut-out must match the 22 mm specification for correct fit and sealing. NEMA 1, 2, 3, 3R, 4, 4X and 12 ratings confirm the enclosure compatibility. REACH, RoHS and WEEE (2012/19/EU) compliance covers material restrictions. Low-voltage operation aligns with standard control-circuit practice.

Questions about this item
How often will the metal head and bezel of this 22 mm push button need replacement under normal use?
The metal head and bezel are built for industrial durability; no scheduled replacement interval is defined for the operator itself.
What NEMA or IP rating limits continuous operation in a wet or dusty environment?
Rated NEMA 1, 2, 3, 3R, 4, 4X, 12 and IP66, IP67, IP69, IP69K, so the enclosure seal is the first limit under sustained exposure.
Does the momentary action generate noticeable heat or noise when pressed repeatedly all day?
As a low-voltage mechanical operator with no internal electronics, it produces no measurable heat and only a light tactile click.
