Abstract
Abstract A switch, as for a windshield wiper, has a housing, a carriage rotatable in the housing in opposite directions from a first position to respective second and third positions, one or more electrical contacts mounted on and moving with the carriage, a conductive contact surface fixed in the housing for engagement by the contacts moving with the carriage, a primary actuation member which is manually actuatable from a first to a second position and may control a windshield washer, a drive member carried by the primary actuation member along a path, a resilient reaction member affixed to the carriage and extending into the path of the drive member for engagement therewith and displacement thereby, and wherein the carriage is displaced from the first to the second position by the displacement of the reaction member. The reaction member is the cantilevered arm of a torsion spring. When the carriage is manually actuated through its first position toward its third position, the cantilevered arm of the torsion spring engages a stop member, such as the drive member of the primary actuating member, and yields to allow displacement to the third position but provides a return bias to the first position when the manual actuating force is released.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
108 words
An electrical switch comprising: a housing; a carriage movable in said housing between first and second positions; electrical contact means mounted on and moving with said carriage; a conductive contact surface fixed in said housing for engagement by said contact means; first actuating means, said actuating means being manually actuatable from a first to a second position; drive means carried by said first actuating means along a path; resilient reaction means affixed to said carriage and extending into said path for engagement with and displacement by said drive means; and said carriage being displaced from said first to said second position by said displacement of said reaction means.
Claim 2
Dependent Claim
108 words
An electrical switch comprising: a housing; a carriage movable in said housing between first and second positions; electrical contact means mounted on and moving with said carriage; a conductive contact surface fixed in said housing for engagement by said contact means; first actuating means, said actuating means being manually actuatable from a first to a second position; drive means carried by said first actuating means along a path; resilient reaction means affixed to said carriage and extending into said path for engagement with and displacement by said drive means; and said carriage being displaced from said first to said second position by said displacement of said reaction means.
Claim 3
Dependent Claim
17 words
The switch of claim 1 wherein said reaction means is the centilevered arm of a torsion spring.
Claim 4
Dependent Claim
20 words
The switch of claim 2 wherein said carriage is rotatably mounted for rotation between said first and said second positions.
Claim 5
Dependent Claim
18 words
The switch of claim 1 wherein said drive means is a rigid appendage of said first actuating means.
Claim 6
Dependent Claim
16 words
The switch of claim 4 wherein said first actuating means is biased to said first position.
Claim 7
Dependent Claim
103 words
The switch of claim 1 wherein said carriage is further movable between said first and a third position, said first position being intermediate said second and said third positions, and including handle means connected to said carriage for manually actuating said carriage from said first at least to said third position, stop means, said stop means being positioned to engage said reaction means as said carriage is manually moved from said first toward said third position, and said reaction means resiliently yielding thereby to bias said carriage to return to said first position from said third position when said handle means is released.
Claim 8
Dependent Claim
14 words
The switch of claim 6 wherein said drive means is also said stop means.
Claim 9
Dependent Claim
38 words
The switch of claim 7 wherein said first actuating means is biased to its said first position and includes a rigid appendage forming said drive means, and said reaction means comprises the cantilevered arm of a torsion spring.
Claim 10
Dependent Claim
29 words
The switch of claim 8 including detenting means cooperatively associated with said carriage and said housing for yieldably maintaining said carriage at the respective said first and second positions.
Claim 11
Dependent Claim
25 words
The switch of claim 8 wherein said carriage is rotatably mounted for rotation in opposite directions between said first, said second and said third positions.
Claim 12
Dependent Claim
22 words
The switch of claim 10 wherein said first actuating means is linearly reciprocable between its respective said first and said second positions.
Claim 13
Dependent Claim
68 words
The switch of claim 11, said switch being adapted to control energization of a wiper motor between "off" and "on" conditions, said contact surface and said contact means being operative in said carriage first position to place a said wiper motor in the "off" condition and in both of said second and said third positions of said carriage to place a said wiper motor in the "on" condition.
Claim 14
Dependent Claim
99 words
The switch of claim 12, said switch being adapted to also control energization of a washer motor between "off" and "on" conditions, said first actuating means including other contact means mounted thereon and moving therewith, said contact surface also being positioned and structured for engagement by said other contact means, said contact surface and said other contact means being operative in said first position of said first actuating means to place a said washer motor in the "off" condition and in said second position of said first actuating means to place a said washer motor in the "on" condition.
Claim 15
Dependent Claim
146 words
The switch of claim 5, said switch being adapted to control energization of both a wiper motor and a washer motor between respective "off" and "on" conditions, said contact surface and said contact means being operative in said carriage first position to place a said wiper motor in the "off" condition and said second position of said carriage to place a said wiper motor in the "on" condition, and said first actuating means including other contact means mounted thereon and moving therewith, said contact surface also being positioned and structured for engagement by said other contact means, said contact surface and said other contact means being operative in said first position of said first actuating means to place a said washer motor in the "off" condition and in said second position of said first actuating means to place a said washer motor in the "on" condition.
