A steering column switch assembly for motor vehicles comprising a steering column disposed below the hub of the steering wheel, a first switch housed in said steering column and associated with a turn indicator device, an elongated lever extending through said steering column, one end of said lever being adapted to operate said first switch when selectively rotated in the direction parallel to the plane of the steering wheel while the other end thereof being mounted with a handle, a second switch housed in said steering column and associated with a head-light controlling device so as to be operated by a portion of said lever adjacent to said first mentioned end of the lever when the latter is shifted in the direction at right angles to the plane of the steering wheel, a third switch housed in said handle and adapted to be oPerable in the circumferential direction with respect to the lever for operating a windshield wiper motor, said third switch including a casing which constitutes a part of the handle having an enlarged chamber provided with a nail portion, a conductive stop ring having a plurality of detent holes and an arc-shaped clearance for limiting rotation of the handle in cooperation with said nail portion and nonrotatably mounted on the second mentioned end of the lever, a carrier ring including a detent member, a resilient member for collapsibly urging said detent member toward said stop ring and a contact strip and formed on its periphery with a keyway engageable with said nail portion, and an anchor ring including a pair of terminal members adapted to be bridged by said contact strip at one selected position of the carrier ring, whereby said carrier ring can be rotated in response to rotation of the handle to give an electric switching action, and a fourth switch housed in said handle adjacent to said third switch and adapted to be operable in the axial direction with respect to the lever for operating a windshield washer motor.
Claim 3
Dependent Claim
31 words
The steering column switch assembly according to claim 1, wherein said third switch has three switching positions defined by positioning the detent member to any selected one of the detent holes.
Claim 4
Dependent Claim
153 words
The steering column switch assembly according to claim 1, wherein said fourth switch comprises a casing which constitutes a part of the handle having an enlarged chamber provided with a nail portion, a plug adapted to enclose said handle so as to close the chamber, a conductive washer non-rotatably mounted on the lever at a position adjacent to the outer extremity of the lever, a conductive member seated against the inner surface of said plug, a compression spring interposed between said washer and conductive member, a fixed contact member, and an insulating pad having an axially extending hole in which said contact member is accommodated, said casing and plug being normally urged in one direction away from said contact member, whereby, when the handle is moved in the axial direction with respect to the lever, said fourth switch can be closed by means of engagement between the contact member and the conductive member.
Claim 5
Dependent Claim
183 words
The steering column switch assembly according to claim 1, wherein one of said terminal members is connected with a shunt winding of a windshield wiper motor, which is in turn connected with the power source, through a second relay switch of a relay assembly having a first relay switch, a relay coil and a resistor interposed between said first and second relay switches, and the other terminal member is connected in series with the power source through the relay coil whereby, when the handle is rotated to one position wherein the both terminal members are connected to the ground, a line connecting between the motor to the ground and a line connecting between the shunt winding to the ground are respectively established to short-circuit the resistor so that the motor can be driven at low speed and, when the handle is further rotated to another position wherein only one of said terminal members connected with the relay coil is connected with the ground, said two lines are respectively established without short-circuiting the resistor so that the motor can be driven at high speed.
Claim 6
Dependent Claim
206 words
The steering column switch assembly according to claim 1, wherein one of said terminal members is connected with the power source through a first relay coil while the other terminal member is connected with the power source through a second relay coil of a relay assembly having a pair of first and second relay switches, one of which being associated with the first relay coil and the other of which being associated with the second relay coil whereby, when the handle is rotated to one position in which the terminal member connected with the power source through the first relay coil is connected with the ground so as to cause the first relay switch to Connect one terminal of the wiper motor to the ground through the second relay switch while a second terminal of said motor is connected with the power source, the motor can be driven at low speed and, when the handle is further rotated to another position in which the both terminal members are connected with the ground so as to cause the first and second relay switches to connect a third terminal of the motor to the ground through said both relay switches, the motor can be driven at high speed.
