Description
NOVA CAM SWITCHES series NCS have been developed to the latest achievements in the field of switching devices through the application of high quality insulation material and contacts made from silver alloys. Their advantages are high making and breaking capacities, electrical and mechanical endurance and small dimensions. The rotary cam switches are intended for multiple switching operations in main circuit as well as in auxiliary circuits.
NOVA NCS series rotary cam switches have five current ratings: 20A, 25A, 32A, 40A and 63A. All ratings has the finger proof terminal (except for 40A and 63A) The series comply with IEC 60947-3, IEC 60947-5-1.
NOVA NCS series mainly applies to 600Vac and below voltage (240Vac/50 Hz) as well as DC circuit. Typical applications are breaking and closing, change-over of circuit, selector switches (for example: Auto-Manual), control switch of switchgear / control gear and control switch of instruments.

Application
The NCS series cam switches can be used for virtually all purposes which classified by utilization as the following:
- Motor switches - these switches are designed for direct-online starting and stopping of single phase and three phase motors, which also come out as star-delta switches, reversing switches, pole-change over motor switches.
- Selector switches and multi-step switches - e.g. Voltmeter selector switches, Ammeter selector switches and etc. for transformers and welding apparatuses.
- Cut-Off switches or ON-OFF switches in auxiliary circuits - these switches are assembled in compliance with the switching programmer according to preference : switches for control, signaling and measuring circuits.
- Control switches with spring return - pull to operate and etc.
- NOVA Cam switches can have up to 15 layers (30 contacts) in maximum. In principle all sizes and designs of cam switches can be arranged with four different angles of rotation. Suitable to the application of stop mechanism with 90°, 60°, 45°, 30° at uniform distribution of a full circle, maximum 4, 6, 8 or 12 switch positions are possible.
- The switches can be used at the ambient temperature from -5°C to +55°C and storage temperature
- from -20°C to +70°C
