Overview

The CS series rotary cam switches are engineered for versatile switching tasks in main and auxiliary electrical circuits, primarily targeting motor control applications such as direct-online starting/stopping, star-delta switching, reversing, and pole-change operations. They also support auxiliary functions including control, signaling, measurement circuits, resistor and heater group switching, and automatic return control switches.

Key Advantages

• High making and breaking capacities for reliable load switching.
• Robust electrical and mechanical endurance ensuring long service life.
• Compact design for easy integration into control panels.

Standards Compliance

The switches meet international and national standards: IEC/EN 60947-3, VDE 0660, TS EN 60947-3, and BS 5419, guaranteeing safety and interoperability.

Designation and Coding

Product codes follow the format: CS XX(Ith[A]) YY(diagram) Z_(design), where XX denotes thermal current rating, YY the switching diagram, and Z the design variant.

Switch Types and Configurations

• ON-OFF Switches: Basic 60° switching angle, available in 1 to 4 poles, current ratings from 10A to 100A.
• Multistep Switches: Multiple switching positions with 60° steps.
• Voltmeter and Ammeter Switches: 1 to 3 poles, some with transformer integration for measurement circuits.
• Changeover Switches: 1 to 3 poles, enabling switching between two circuits.
• Start and Run Switches: For single-phase motor control with 0-start-1 sequence.
• Star-Delta Switches: For motor starting using star and delta configurations.
• Motor Reversing Switches: 1-0-2 and L-0-P sequences for reversing motor direction.
• Emergency ON-OFF Switches (LK version): Padlockable in 'off' position, red handles with yellow background for safety compliance.
