Siemens SIRIUS ACT 22mm comutador rotativo azul 3SU1032-2BC, 2 posições, 1NO 3SU10322BC500AA0

The Siemens 3SU1032-2BC is a 22mm selector switch from the SIRIUS ACT series, distinguished by its short blue actuator and robust plastic construction. Unlike conventional toggle switches, this latching selector switch provides a clear visual indication of its two positions (O-I) and is engineered for high mechanical durability, making it suitable for frequent manual operations in industrial control panels.

Highlights

• 22mm round mounting diameter for standard panel cut-outs
• Latching 2-position selector switch (O-I) with 90° actuating angle
• 1 normally open (NO) contact with screw terminals
• Blue actuator and black front ring, both made of plastic
• High mechanical durability: 10,000,000 switching cycles

In daily use

This selector switch is ideal for control circuits requiring a maintained two-position input, such as mode selection or manual override. The short actuator profile reduces accidental operation while remaining easy to grip. Its screw terminals accept standard conductors, and the switch fits panels with a 22mm diameter hole, a common industrial standard.
