30 mm Red Mushroom Push Button

This SIEMENS 52PM9V2 is a 30 mm mushroom head push button operator designed for industrial control panels. It features a momentary action with a 63 mm red plastic head mounted on a chrome-plated zinc die-cast bezel. The metal construction suits low-voltage industrial applications requiring a durable manual input device.

Suited for NEMA 4X and IP66 panels

This operator fits panels needing NEMA 1, 3, 3R, 4, 4X, 12 or 13 ratings and IP protection up to IP66. It is not suited for applications requiring a maintained latch action, illuminated head, or a different head diameter. Buyers needing a key-operated or twist-to-release mechanism should look at other operator types.

30 mm mounting diameter decides fit

The single specification that determines compatibility is the 30 mm mounting size. Verify the panel cut-out matches this dimension exactly before purchase. The NEMA and IP ratings confirm suitability for the intended enclosure environment.

Questions about this item

Which mushroom head diameter should I select for a 30 mm panel cut-out?

The 63 mm mushroom head is built for the 30 mm mounting hole, so it fits directly without adapters.

What does the momentary action mean when the button is wired into a control circuit?

Pressing the red mushroom head closes the circuit only while held; it opens automatically when released.

How do the NEMA and IP ratings limit where this operator can be installed?

Ratings NEMA 1, 3, 3R, 4, 4X, 12, 13 and IP10, IP11, IP14, IP52, IP54, IP56, IP66 allow indoor and outdoor use with protection against dust, water jets and temporary submersion.
