SIEMENS Push Button Operator 30mm Maintained Mushroom Red

30 mm maintained mushroom operator

The Siemens push-button operator mounts in a standard 30 mm panel cut-out and uses a 45 mm red mushroom head that stays in the actuated position until pulled back. Its plastic head and bezel sit on a chrome-plated zinc die-cast bezel, and the assembly carries NEMA 1, 3, 3R, 4, 4X, 12 and 13 ratings plus CSA and UL listings.

Industrial panels needing a maintained emergency

This operator suits control stations that require a push-to-lock, pull-to-reset action with a highly visible red head. It is not intended for momentary circuits, illuminated applications or installations that demand a smaller head diameter or a different colour code.

Single 30 mm cut-out with broad environmental

The unit fits one 30 mm opening and the NEMA 4X and 13 ratings mean it withstands hose-directed water, oil and non-corrosive coolants. Headroom ends where a momentary return, keyed reset or a different voltage-rated contact block is required, since the operator itself provides only the mechanical latch.
