Siemens P30S3MRB5 Selector Switch 3 Position Round Knob

Siemens 22 mm round selector switch with a three-position I, O, II configuration and a compact yellow plastic knob, built for panel mounting in control cabinets and machinery. This illuminable, short-actuating selector switch provides a left-side momentary contact and a right-side latching contact, activated through a 2×45° sweep with defined actuation at 10:30, 12:00 and 13:30 hours. Laser labeling delivers clear, uppercase field markings, and the unit ships with a holder for secure installation in standard 22 mm cutouts. Ideal for operator interfaces requiring a compact, three-position control—such as start/stop, mode selection, or direction changes on industrial equipment—the P30S3MRB5-style family offers reliable tactile feedback and straightforward wiring in a 22 mm panel footprint.
