The PSA040KD134S is a mechanical cam switch from the PS series, designed without its own power consumption. It operates as a changeover switch in 1-0-2 configuration — two source positions and an off centre position — making it suitable as a main switch or group switch for controlling single-phase drives, signalling circuits, and measuring circuits in AC systems rated 220–400V.

The switch features an IP54 enclosure, AgNi contact material, a 60° spin angle, and a compact 64×64 mm frame. Mechanical life is rated at 100,000 operations and electrical life at 50,000 operations.
