Claims
- 1. A switching mechanism adapted to energize a motor in response to selective actuation of a plurality of switches to rotate an output shaft of the motor by an angle dependent upon the particular switch which is actuated, said switching mechanism comprising:
- a base body carrying a plurality of brushes arranged symmetrically relative to a reference axis, each brush including a plurality of slide terminals arranged in a comb-like formation,
- a circuit board carrying a plurality of circumferentially extending conductor paths, at least one of which constitutes a common conductor path, and others of which constitute switch conductor paths adapted to be connected to respective ones of the switches,
- said base body and circuit board being superimposed such that said slide terminals slidably contact said conductor paths,
- said base body adapted to be connected to the output shaft of the motor to be rotated thereby relative to said circuit board about said axis, causing said slide terminals and said conductor paths to undergo relative rotation,
- said switch conductor paths including first portions arranged to lie on different circumferences relative to said axis, and end edge portions all arranged to lie substantially on a common circumference relative to said axis and to be circumferentially spaced from one another.
- 2. A switching mechanism according to claim 1 including said switches being arranged for selecting damper-opening/closing positions of a vehicle air conditioner.
- 3. A switching mechanism according to claim 1, wherein said common circumference is defined by a radius which is larger than the radii defined by said mutually different circumferences of a plurality of said conductor path first portions.
- 4. A switching mechanism according to claim 1, wherein said plurality of conductor path first portions are disposed radially inwardly relative to their respective end edge portions.
