30 mm Mushroom Push Button

The SIEMENS 52PM9W2J is a 30 mm mushroom-head push button designed for industrial control panels. Its momentary action and single normally closed contact suit emergency-stop or safety-interlock circuits. The red plastic head provides clear visual identification in machinery environments.

The operator features a chrome-plated zinc die-cast bezel and a 44 mm plastic mushroom head rated for NEMA 1, 3, 3R, 4, 4X, 12 and 13 enclosures. Pressure-plate terminals accept wiring without specialised tools. The unit carries IP ratings from IP10 through IP66 for dust and water ingress protection.

Electrical Ratings in Use

Questions about this item

What does the A600/P600 contact rating mean for the 600V AC switching capacity?

The A600/P600 NEMA designation confirms the contact block is rated for 10A at 600V AC, suitable for heavy-duty industrial control circuits.

What panel cut-out and mounting depth does the 30 mm operator with 44 mm mushroom head require?

It fits a standard 30 mm panel cut-out; the chrome-plated zinc die-cast bezel and plastic head mount from the front with a pressure-plate terminal block on the rear.

How is the single 1NC contact block wired, and which step is most often missed?

Insert stripped wires into the pressure-plate terminals and tighten the screws; the step most often missed is verifying the terminal screws are fully secured to prevent loose connections.
