Thumb-Pushwheel Switch
Description: A thumb-pushwheel switch is a manually operated electromechanical switch that allows users to select numeric values or positions by rotating a wheel with their thumb. Commonly used in older digital devices for setting time, date, channel, or other numeric inputs.
- Type: Rotary Encoder / Mechanical Stepped Switch
- Positions: Typically 0–9 per digit
- Poles: Single or multiple digits (e.g., 4-digit)
- Mounting: Panel mount, PCB mount
- Applications: Test equipment, industrial controls, vintage electronics
- Interface: Direct mechanical encoding (BCD or decimal output)
Note: Unlike rotary encoders, pushwheel switches provide absolute position feedback and do not require power to retain state.
