30 mm mushroom push button

The Schneider Electric 9001KR4B is a momentary push button with a 35 mm metal mushroom head and black metal bezel. It fits a 30 mm mounting cut-out and is rated NEMA 1, 2, 3, 3R, 4, 6, 12, 13 plus IP66 for dust and water ingress. The operator meets REACH and RoHS requirements and contains no SVHC substances.

Industrial control panels needing a rugged

This operator suits panels that require a large, easy-to-locate button for emergency stop, start or reset functions in harsh environments. Installations needing a maintained latch, illuminated head, integrated contact blocks or a legend plate must select a different operator or add separate components.

Sustained exposure to dust.

The IP66 and broad NEMA ratings mean the metal head and bezel maintain sealing during prolonged wash-downs, outdoor weathering and dusty atmospheres. Momentary action returns instantly when released, so the mechanism endures repeated cycling without latch wear or contact degradation.

Questions about this item

What mounting hole size must my panel have for the 30 mm mushroom head to fit?

Cut a 30 mm hole in the panel; the operator is designed for that exact cut-out.

Will the IP66 and NEMA 4 ratings survive the same wash-down environment as my older NEMA 12 enclosure?

Yes — the push button meets IP66 and NEMA 1, 2, 3, 3R, 4, 6, 12 and 13, so it matches or exceeds NEMA 12 protection.

How can I confirm the momentary action is working once the button is wired?

Press the black mushroom head — the circuit closes only while you hold it and opens the moment you release.
