40A reversing switch, direction of rotation changeover switch L-0-P, long black knob SK40-3.8368\P09

Cam switch – reliable load switching

This 40A rated cam switch is a robust solution for frequent switching of electrical circuits. It finds application in both industrial installations and more demanding home applications. This model is primarily distinguished by its versatility – thanks to the L-0-P construction, it allows changing the direction of rotation of electric motors, which is particularly useful in devices requiring precise motion control. The long, black knob provides convenient and secure operation even in difficult conditions.

Construction and application

The SK40 cam switch is a component designed for safe and efficient switching of electrical circuits. Its cam-based design ensures high reliability and durability, even with intensive use. The L-0-P direction of rotation switch allows controlling electric motors by reversing their direction of operation. This is an ideal solution in applications such as garage doors, fan drives or industrial machines. Made of high-quality materials, the switch is resistant to mechanical damage and ensures long-term, trouble-free operation.

Key features and parameters

This switch is characterized by a rated current of 40A, allowing connection of devices with significant power consumption. It ensures safety thanks to the rated insulation voltage of 690V. The maximum current it can safely switch is 80A (rated switching current). The switching angle in the range of 45°-90° guarantees smooth and precise circuit switching. The IP65 protection degree (with respect to the panel) protects against access of solid objects and water jets, enabling use in harsh environmental conditions. Mechanical durability of 3.0 million switching cycles ensures long-lasting and reliable operation of the device. It allows connection of cables of different thickness and type – rigid with a cross-section of 16…35 mm² and flexible with a cross-section of 16…25 mm². It can operate in a wide range of ambient temperatures from -40 to +70°C.

This switch is also characterized by high resistance to vibrations and mechanical shocks, making it an ideal choice for industrial applications and in places exposed to intensive use. Solid construction and high quality workmanship ensure long-lasting and trouble-free operation of the device for many years.
