Abstract
Abstract A combination windscreen washer and wiper timing control switch, characterized in that it comprises a control lever adapted to control, by rotation the windscreen wiper motor and, by tilting, the windscreen washer motor. Fixed case having tiltably mounted therein a body or box lever which forms a rod adapted to rotate about its axis in said box. Also provided is a pair of sliding contacts electrically interconnected and co-acting with contact studs or segments corresponding to the different rated speeds of the windscreen wiper motor. One of the segments comprises a resistive track engaged by one of the sliding contacts to form therewith a rheostat for adjusting the switch timing.

Claim 1
Independent Claim
189 words
A control switch for a windscreen washer, electrically connected to a washer motor, and a windscreen wiper, electrically connected to a wiper motor and operative at different rated speeds, comprising: a. a fixed casing; b. a box, mounted within the casing, wHich may be tilted with respect to the casing, said box having a contact stud and first and second conductive segments, in which said first segment comprises a resistive track; c. means for closing a circuit for the electric washer; and d. a control lever, connected within the box and rotatable about its axis, said control lever including a rod, having first and second sliding contacts, said rod being rotated to one position to connect, respectively, said first and second sliding contacts with said first and second conductive segments, said first sliding contact and said first segment forming a rheostat for electrically adjusting switch timing for the timed operation of the electric wiper, and being rotated to a second position to connect one of said sliding contacts with said contact stud for coninuous operation of the electric wiper, and said rod being tilted to operate the electric washer.
Claim 2
Dependent Claim
189 words
A control switch for a windscreen washer, electrically connected to a washer motor, and a windscreen wiper, electrically connected to a wiper motor and operative at different rated speeds, comprising: a. a fixed casing; b. a box, mounted within the casing, wHich may be tilted with respect to the casing, said box having a contact stud and first and second conductive segments, in which said first segment comprises a resistive track; c. means for closing a circuit for the electric washer; and d. a control lever, connected within the box and rotatable about its axis, said control lever including a rod, having first and second sliding contacts, said rod being rotated to one position to connect, respectively, said first and second sliding contacts with said first and second conductive segments, said first sliding contact and said first segment forming a rheostat for electrically adjusting switch timing for the timed operation of the electric wiper, and being rotated to a second position to connect one of said sliding contacts with said contact stud for coninuous operation of the electric wiper, and said rod being tilted to operate the electric washer.
Claim 3
Dependent Claim
67 words
The control switch of claim 1 wherein said means for closing comprises: a. a first contact fixedly mounted on said casing; b. a second contact mounted on said box; and c. a spring connected between said box and said casing wherein said box may be tilted against the resistance of the spring to connect said first and second contacts so as to operate the electric washer motor.
