22 mm White Selector Switch for Industrial Panels

The SIEMENS 3SU1150-2BL60-1LA0 is a 22 mm three-position selector switch designed for industrial control panels. It features a maintained action across all three positions with a 2NO/2NC contact configuration. The white lever operator provides clear visual identification in control panel layouts.

Replaces Worn Selector Switches in Existing

This switch serves as a direct replacement for failed or ageing 22 mm selector units in industrial machinery. The upgrade is worth it when contact reliability has degraded or when NEMA 4, 4X, 12 and IP66, IP67, IP69, IP69K sealing is required for harsh environments. The metal bezel and basic material ensure durability in demanding applications.

Rated for 10 A at 600 V AC and 1 A at 600 V DC

The switch carries NEMA A600/R300 contact ratings suitable for standard industrial control circuits. It is not designed for high-power switching beyond these ratings or for applications requiring keyed operation. The plastic operator head and metal construction limit use to environments compatible with these materials.

Questions about this item

What panel cut-out size does the 22 mm selector switch require?

The switch mounts in a standard 22 mm cut-out and is secured with the supplied fixing nut; ensure the panel thickness matches the clamp range.

How is the selector switch wired and what is the common wiring error?

Wire the 2NO/2NC contacts to the screw terminals; the frequent mistake is swapping the normally-open and normally-closed pairs, which reverses the XOXO switching logic.

Which components may need replacement after extended use?

The plastic operator head and internal contact blocks can wear; the switch carries IP20, IP66, IP67, IP69 and IP69K ratings plus NEMA 1, 2, 3, 3R, 4, 4X and 12 for harsh environments.
