Abstract
Abstract A switch for use with an automatic transmission drive selector lever of a road vehicle in which the contacts of the switch are arranged with sufficient clearance therebetween to avoid arcing between the contacts and permit physical mounting of the contacts while allowing the switch to be operated by a small angular movement. Thus, the switch may be mounted in the very small space available since the moving contact moves through a larger angular distance than the input member or shaft thereby enabling the fixed contacts to be easily accommodated.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
114 words
An electrical switch including a body, a shaft mounted in the body for rotation about a first axis relative to the body, a movable substantially ring-like member disposed about said first axis and mounted for rotation relative to the body about a second axis parallel to, but spaced from, said first axis, contacts carried by said movable member, means coupling said shaft to said movable member so that said member is rotated relative to the body when said shaft is rotated, the angular direction of rotation of said member being the same as that of said shaft, and fixed contacts carried by said body and engagable by the contacts carried by said movable member.
Claim 2
Dependent Claim
114 words
An electrical switch including a body, a shaft mounted in the body for rotation about a first axis relative to the body, a movable substantially ring-like member disposed about said first axis and mounted for rotation relative to the body about a second axis parallel to, but spaced from, said first axis, contacts carried by said movable member, means coupling said shaft to said movable member so that said member is rotated relative to the body when said shaft is rotated, the angular direction of rotation of said member being the same as that of said shaft, and fixed contacts carried by said body and engagable by the contacts carried by said movable member.
Claim 3
Dependent Claim
39 words
The switch as claimed in claim 1 wherein the means coupling said shaft to said movable member includes a rotor movable with said shaft, said rotor including a post which engages a radially extending slot in said movable member.
Claim 4
Dependent Claim
24 words
The switch as claimed in claim 1 wherein said movable member is a printed circuit board having a plurality of exposed conductive areas thereon.
Claim 5
Dependent Claim
87 words
The switch as claimed in claim 1 wherein said shaft is adapted to comprise a selector shaft of an automatic transmission of a road vehicle and said fixed contacts carried by said body are adapted to be connected in a reversing light circuit and a starter motor circuit of the vehicle respectively, with said reversing light circuit being completed when said selector shaft is in the reverse drive position, and said starter motor circuit being completed when said selector shaft is in the park and neutral positions.
