Patent

CA 2537687

To provide a dimmer switch capable of switching between on and off states and between low beam and high beam of a light by a same operation, and free from an erroneous operation. A dimmer switch takes the form of a rotary switch including a stationary portion fixed to a vehicle and an operable rotary portion, and is constructed such that switching between a high beam position and a low beam position is made by a rotational operation in opposite directions at a same position in an axial direction of the rotary portion. In addition, the rotary portion is slidable in the axial direction, and a rotational operation to switch from the low beam position to the off position can not be made without the sliding movement of the rotary portion. Hence, switching from one of the high beam, low beam, and off positions to another can be made by a same rotational operation, while an erroneous operation to switch to the off state when a switching from high beam to low beam is to be made is prevented. Further, when biasing means to act against the sliding movement is provided and/or when the sliding movement is enabled even from the high beam position, user-friendliness is enhanced.
