22 mm Three-Position Illuminated Selector Switch

This SIEMENS 3SU1150-2BM60-1LA0 is a 22 mm panel-mount selector switch with three momentary positions and integrated illumination. It carries a 10A rating at 600V AC and 1A at 600V DC, suited for industrial control panels that require clear visual status indication. The operator head uses white plastic with a silver metal bezel, while the base material is metal for durability. NEMA ratings 1, 12, 2, 3, 3R, 4, 4X and IP ratings IP20, IP66, IP67, IP69, IP69K confirm broad environmental protection.

Panel Cut-Out and Contact Configuration

The switch fits a standard 22 mm mounting hole and provides a 2NO/2NC contact form without a cam included. Its momentary action at every position means the lever returns to centre when released, which suits jog or inch control schemes. The A600/R300 NEMA contact designation indicates suitability for heavy-duty pilot-duty circuits. No key removal is featured, so the lever remains permanently attached. Wiring terminates at the contact block behind the panel, leaving the front face uncluttered.

Environmental Sealing and Electrical Load

Rated IP66, IP67, IP69 and IP69K, the operator withstands high-pressure wash-down and temporary immersion, making it appropriate for food-processing or outdoor equipment. The 10A AC and 1A DC ratings define the maximum resistive load the contacts can switch reliably. Silver bezel metal and plastic operator head resist corrosion and mechanical wear in normal industrial atmospheres. Power draw is limited to the control-circuit coil current of the connected contactor or relay.

Questions about this item

How much current can the 10 A AC contacts handle continuously before heat becomes a limiting factor?

The selector switch is rated for 10 A at 600 V AC under the A600 designation, which defines its continuous thermal limit for the contact block.

Does the IP69K-rated operator generate noticeable heat or noise during all-day operation?

The device has no moving parts that produce sound, and the contact block dissipates minimal heat at rated load, so it runs silently and stays cool in continuous use.

What contact-block series must I already own to mount this 22 mm illuminated operator?

The 22 mm operator fits SIEMENS 3SU1 contact blocks with the standard 2NO/2NC configuration used in the 3SU1150 series.
