Rotary Heater Control Knob - 2-Position Switch
Compact and high-quality rotary control knob with an integrated 2-position switch, designed for manual control of heater blowers and ventilation systems in vehicles.
The control features two positions, OFF/ON, making it easy to switch the fan on and off.

A chrome-finished logo in the centre gives the control a classic and stylish appearance.
The switch is designed for fans and blower motors equipped with an integrated resistor pack. Its compact design makes it suitable for installation in dashboards and control panels.
