Abstract
A switch ( ) for controlling operation of vehicle lamps (e.g., ) comprises a base ( ) and a manually engageable assembly ( ) rotatable about an axis ( ) relative to the base for controlling operation of the lamps. The assembly ( ) comprises a magnetic member ( ) that rotates with the assembly about the axis ( ). The base ( ) comprises at least one magnetic sensor (e.g., ) and control circuitry connecting the sensor with the vehicle lamps (e.g., ). The magnetic member ( ) is rotatable about the axis ( ) into a plurality of different rotational positions relative to the sensor (e.g., ) to provide an output signal at the control circuitry ( ) that is indicative of the relative rotational position of the assembly ( ). The magnetic member ( ) is spaced apart from the base ( ) to provide contactless operation of the switch ( ).
