Siemens Selector switch, illuminable, screw, 3-position, 1NO, 22mm Part number 3SU1100-2BM60-1NA0

Product Overview

The Siemens 3SU1100-2BM60-1NA0 is a SIRIUS ACT selector switch — a 22 mm, round, plastic, illuminable selector switch with a short actuator. It features three switch positions (I > O < II) with momentary-contact operation (return on release), suitable for control panels and user-interfaces in industrial control and automation systems.

Key Features

• 22 mm round selector switch, plastic housing, short actuator
• Illuminable design (supports optional light source)
• Three switch positions: I > O < II (momentary contact, return-on-release)
• Single command point (one actuator per unit)
• Standard screw-terminal contact module(s)
• Suitable for installation in control panels, operator consoles or machine-control stations
• SIRIUS ACT modular system: compatible with associated holders and contact modules
