Flush Push Button 22 mm Green

This Siemens flush push button operator fits a standard 22 mm panel cut-out and provides momentary action for control circuits. The green plastic head and metal bezel suit industrial panels that require colour-coded operator identification.

1NO/1NC Contact Block Included

The unit ships with a 1NO/1NC contact arrangement rated at 10A at 600V AC and 1A at 600V DC, matching NEMA A600/R300 designations. Screw terminals allow secure field wiring without special tooling.

NEMA and IP Environmental Ratings

The operator carries NEMA type 1, 12, 2, 3, 3R, 4, 4X ratings and IP66, IP67, IP69, IP69K ingress protection, so it withstands wash-down and outdoor exposure. It is not suited for applications requiring illuminated indication or maintained switching action.

Questions about this item

Will the 1NO/1NC contact block need periodic replacement under normal use?

The contacts are rated for 10 A at 600 V AC and 1 A at 600 V DC with an A600/R300 NEMA designation, so replacement depends on actual switching frequency and load rather than a fixed interval.

What limits continuous operation of the 22 mm green flush push button?

The operator carries NEMA 1, 12, 2, 3, 3R, 4, 4X and IP66, IP67, IP69, IP69K ratings; the first limit reached will be the contact electrical rating of 10 A at 600 V AC or the mechanical endurance of the momentary mechanism.

How much heat does the screw-terminal contact block generate when carrying 10 A all day?

At the rated 10 A and 600 V AC the contact block dissipates only the normal resistive loss of the screw terminals; no forced cooling is required and the plastic head with metal bezel remains within its NEMA and IP temperature envelope.
