SIEMENS 22 mm Extended Push Button
The SIEMENS 3SU1050-0BB20-0AA0 is a red extended push button designed for 22 mm panel mounting. It suits operators who need a momentary, non-illuminated actuator in industrial control panels or machinery interfaces. The metal head, bezel and basic material withstand repeated use in demanding environments. Buyers who need an illuminated or maintained-contact operator should look elsewhere.
Sealed to IP66, IP67, IP69 and IP69K
The actuator meets NEMA 1, 2, 3, 3R, 4, 4X and 12 ratings alongside the IP66, IP67, IP69 and IP69K ingress protection levels. This sealing resists dust, water jets, high-pressure washdown and temporary immersion during sustained operation. The low-voltage design remains compliant with REACH, RoHS and WEEE 2012/19/EU directives throughout its service life. Installations that require higher voltage ratings or different environmental certifications cannot use this unit.
Fits standard 22 mm cut-outs with metal construction
Installation uses the common 22 mm mounting diameter, and the all-metal construction provides mechanical rigidity without additional reinforcement. The momentary action returns automatically when released, reducing wiring complexity for simple control circuits. Panels thicker than the unspecified maximum clamp range or cut-outs outside the 22 mm standard will prevent correct fitting.

Questions about this item
How much heat or noise does the 22 mm extended push button generate when pressed continuously all day?
The push button is a passive mechanical component with no internal power source, so it produces no heat and no audible noise during continuous operation.
What mounting hardware or panel cut-out must I already have to install this 22 mm operator?
A standard 22 mm panel cut-out is required; the metal bezel and threaded body mount directly into that opening without additional adapters.
Will this IP69K-rated red button fit alongside older 22 mm metal operators already on my panel?
Yes, it uses the industry-standard 22 mm mounting diameter and metal bezel, so it aligns with existing cut-outs and matches the form factor of legacy metal operators.
