20A rotary switch, direction of rotation changeover switch L-0-P, panel mounting front grey knob black SK20-3.8368\P23

Rotary cam switch for changing the direction of rotation

This three-pole rotary cam switch SK20, designed for panel mounting, is a reliable solution for controlling electrical circuits. Designed to operate at voltages up to 690V, it allows you to change the direction of rotation of motors and switch circuits on and off. Made of durable plastic, it provides durability and resistance to mechanical damage.

Construction and application

The SK20 switch with a black knob and gray housing finds application in a wide range of electrical installations – from industrial to commercial. Its segmented construction allows configuration to individual needs, and the possibility of indirect mounting provides flexibility during installation. The L-0-P switch allows you to choose between directions of rotation, switch off the power (position 0) and standard switching on. The IP65 protection class guarantees safe use even in harsh environmental conditions.

Key features and benefits

• Durability and reliability: Made of high-quality plastic, resistant to mechanical damage and external factors.
