SIEMENS 52PM9W2A 30 mm Red Mushroom Push Button 1NO/1NC 10A 600V

30 mm Red Mushroom Push Button for Industrial Panels

This 30 mm mushroom-head push button fits standard industrial control panels and machine consoles. It provides momentary action with one normally open and one normally closed contact rated at 10 A and 600 V AC. The red plastic head and chrome-plated zinc die-cast bezel suit emergency-stop or start functions in manufacturing and process environments.

Check Panel Cut-Out and Wiring Before Ordering

Verify that your panel has a 30 mm mounting hole and enough depth for the pressure-plate terminal block. The operator carries NEMA ratings 1, 3, 3R, 4, 4X, 12 and 13 plus IP ratings up to IP66, so confirm the enclosure rating matches your installation. Ensure the control circuit does not exceed the A600/P600 contact designation and that the wiring method suits pressure-plate connections.

Low Heat and Silent Operation in Normal Use

As a mechanical contact device the button generates negligible heat and draws no power of its own; the 10 A rating simply defines the maximum switched load. Operation is silent apart from the tactile click of the momentary mechanism. The plastic head and metal bezel resist corrosion in damp or wash-down areas, so thermal and acoustic impact on the surrounding cabinet is minimal.
