ON-OFF Switches
ON-OFF switches are used for simple power control in electrical systems. Available from 10A to 600A, they support multiple pole configurations and mounting options including door mount, DIN rail, and base mount.
Typical applications:
- Machine power isolation
- Control panels
- HVAC systems
Changeover Switches
Changeover switches allow switching between two power sources or loads. Common configurations include 1-0-2 (three position) and 1-2 (two position), making them ideal for manual or automatic control systems.
Typical applications:
- Manual / automatic selection
- Remote / local control
- Power source transfer
Reversing Switches
Reversing switches are designed to change the direction of rotation in three phase motors. These switches are commonly used in motor control applications where forward and reverse operation is required.
Typical applications:
- Conveyor systems
- Hoists and lifts
- Industrial machinery
Star Delta Switches
Star delta switches are used to reduce starting current in three phase motors by initially applying lower voltage during startup, then switching to full voltage operation.
Typical applications:
- Motor starting systems
- Pumps and compressors
- Industrial equipment
