Cam switch – reliable circuit switching

This 2-pole cam switch SK20A, combined with the OB2 housing, is a solid solution for switching electrical circuits. The SPAMEL brand product, catalog number SK20-2.8338\OB2, combines durability, safety and functionality. It is an ideal element for both professional installers and end-users looking for a reliable solution in the field of circuit control.

Construction and application

The SK cam switch is a device used for manual switching of electrical circuits. The 1-0-2 version means the ability to choose between two different circuits, and the "0" position is responsible for disconnection. The design based on the cam ensures reliable and precise switching, minimizing the risk of errors and failures. Therefore, the switch finds application in many areas, such as:

• Controlling electric motors
• Switching lighting circuits
• Powering machines and industrial equipment
• Applications in building automation

Construction features and operating parameters

The SK cam switch has been designed with long-term and trouble-free operation in mind. The materials used and the solid construction guarantee resistance to mechanical damage and environmental conditions. The device is characterized by a high degree of protection IP65 (when used with appropriate cover), which ensures safe use even in harsh industrial conditions. The rated insulation voltage is 690 V, allowing safe operation in installations with different voltages. The rated continuous current (Iu=Ith) is 16 A, enabling operation of circuits with significant power consumption. The rated switching current (Ie) is 10 A (AC-21A/AC-22A), determining the maximum current switched by the switch. The IP65 protection class provides high resistance to dust and water, ideal for harsh working conditions. Various mounting methods are available (P03, P04, P23, P24, P07, P27, P08, P28), providing mounting flexibility. The possibility of connecting wires of different thicknesses is ensured by the appropriate cross-section of the connection wires.

It is worth noting the possibility of selecting the appropriate switch cover (I or III), which affects the method of mounting and additional protection against moisture and dirt. The closed cover (III) provides additional safety in demanding applications.
