Product description

The Siemens 3SU1052-2BN40-0AA0 is a 22mm round, metal illuminable selector switch with a shiny green bezel. It features 3 switch positions: I-O<II. The left position (I) is latching, the center (O) is neutral, and the right position (II) is momentary. This actuator has an actuating angle of 2x45 degrees, operating at 10:30h/12h/13:30h.

This green hybrid selector switch is designed for applications where specific color coding is important for function identification, such as 'Start' (latching green) and 'Stop' (momentary red or other). It combines maintained and temporary control actions, useful in industrial automation, machine building, and safety systems.
