Selector switches are manual control devices used in various industrial and electrical applications to select different modes of operation, control circuits, or change the state of a system. They are commonly found in control panels, machinery, and automation systems. Here’s a summary of their key features and uses:
1. Manual Operation:
Selector switches are operated by hand, typically through a rotary knob, lever, or key.
2. Multiple Positions:
They often have two or more positions (e.g., ON/OFF, AUTO/MANUAL, START/STOP) to allow users to choose between different operational modes.
3. Contact Configuration:
They come with various contact configurations (e.g., NO/NC, SPDT, DPDT) to suit different circuit requirements.
4. Durability:
Designed for heavy-duty use, they are built to withstand harsh industrial environments, including exposure to dust, moisture, and vibrations.
5. Mounting Options:
Available in panel-mounted, DIN rail-mounted, or handheld versions for flexibility in installation.
6. Indicators:
Some switches include visual indicators (e.g., LEDs) to show the selected position or status.
Common Applications:
- Motor Control:
Used to start, stop, or change the direction of motors.
- Mode Selection:
Allow operators to switch between automatic and manual control modes in machinery.
- Circuit Switching:
Enable the selection of different circuits or power sources in electrical systems.
- Safety Systems:
Used in emergency stop or safety override systems.
- Process Control:
Facilitate changes in operational parameters in industrial processes.
