Industrial push-button head for control panels

The SIEMENS mushroom head is a 30 mm operator designed for push/pull push-button stations in industrial electrical and automation systems. It mounts on compatible enclosures using a screw-on connection. The metal construction meets NEMA 1, 3, 4 and 12 ratings plus IP66 for dust and water ingress protection.

Green identifier with environmental compliance

The green colour provides clear visual status indication on machinery or process panels. The head is non-illuminated and carries REACH, RoHS and WEEE (2012/19/EU) declarations. No legend plate is included or specified for this variant.

The operator fits panels cut for a 30 mm screw-on fitting and is not compatible with other mounting patterns or illuminated modules. Buyers needing a different diameter, colour, illumination or legend must select an alternative part.

Questions about this item

How is the 30 mm mushroom head installed on a push/pull button?

The operator screws onto the button base using its screw-on connection; the step often missed is ensuring the threads are fully seated before tightening to meet the IP66 seal.

What maintenance or replacement will the metal head need later?

Inspect the screw threads and sealing surfaces periodically; replace the head if corrosion or thread wear compromises the NEMA 1, 3, 4, 12 or IP66 rating.

Which environmental limit appears first during sustained outdoor exposure?

The IP66 rating protects against dust and powerful water jets, but prolonged UV or chemical exposure beyond the REACH, RoHS and WEEE 2012/19/EU compliance scope may degrade the green finish first.
