30 mm Green Mushroom Push Button

The SIEMENS 52PM9W3 is a 30 mm mushroom head push button with a green plastic operator and chrome-plated zinc die-cast bezel. It is built for low-voltage industrial control panels where a momentary, metal-base operator is required. The 44 mm mushroom head gives a large target for fast actuation in noisy or low-light environments.

NEMA and IP ratings define the practical limits

The operator carries NEMA ratings 1, 3, 3R, 4, 4X, 12 and 13 together with IP ratings IP10, IP11, IP14, IP52, IP54, IP56 and IP66. These ratings cover indoor dust and water ingress up to powerful jets, but they do not extend to continuous submersion or high-pressure steam cleaning. Buyers who need a higher IP rating or a different actuator style should look elsewhere.

Panel-mount installation with standard cut-out

The 30 mm mounting diameter fits common industrial panel cut-outs and the metal base secures with a locking nut behind the panel. No special tools are required beyond a standard wrench for the bezel nut. Misalignment of the cut-out or over-tightening the nut can damage the plastic head or compromise the IP seal.

Questions about this item

Which mushroom head diameter should I choose for this 30 mm operator?

The operator uses a 44 mm mushroom head, fixed to the 30 mm mounting size; no other diameter is offered.

What does the momentary action mean when the button is installed in a panel?

Momentary means the contact closes only while the 44 mm green head is held down and opens immediately on release.

Which NEMA and IP ratings apply, and what do they limit in practice?

Rated NEMA 1, 3, 3R, 4, 4X, 12, 13 and IP10, 11, 14, 52, 54, 56, 66; the highest IP66 allows temporary water jets, while lower codes permit only dust or light splashes.
