Abstract
Abstract An improved multicontact switch is disclosed which has a molded plastic body supporting a molded plastic rotor. Metallic contacts are resiliently mounted on the rotor in position to engage and bridge a second set of contacts provided in the form of a printed circuit formed on an inner surface of the switch cover. A versatile multicontact switch pattern is obtained by an appropriate layout of the printed circuit contacts in combination with a particular mounting arrangement of the contacts on the switch rotor.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
182 words
A switch comprising the combination of a hollow switch body, a contact plate attached to said hollow switch body, a movable contact mounting member including a shaft movably mounted on said hollow switch body, a printed circuit formed on a surface of said contact plate having a plurality of fixed contacts, said movable contact mounting member having a plurality of apertures for movable contacts therein, a movable contact mounted in each of said apertures and positioned for being moved by said contact mounting member into bridging relationship with pairs of fixed contacts of said printed circuit, said movable contacts comprising metal members each having a pair of spaced projections and being slidably positioned in said apertures between said spaced projections, springs positioned around said movable contacts between said contact mounting member and one of said projections for urging said movable contacts against said fixed contacts, said hollow switch body having a plurality of integral detents, and the contact mounting member having an integral detent engaging arm positioned for engaging said detents for positioning said movable contacts with respect to said fixed contacts.
Claim 2
Dependent Claim
182 words
A switch comprising the combination of a hollow switch body, a contact plate attached to said hollow switch body, a movable contact mounting member including a shaft movably mounted on said hollow switch body, a printed circuit formed on a surface of said contact plate having a plurality of fixed contacts, said movable contact mounting member having a plurality of apertures for movable contacts therein, a movable contact mounted in each of said apertures and positioned for being moved by said contact mounting member into bridging relationship with pairs of fixed contacts of said printed circuit, said movable contacts comprising metal members each having a pair of spaced projections and being slidably positioned in said apertures between said spaced projections, springs positioned around said movable contacts between said contact mounting member and one of said projections for urging said movable contacts against said fixed contacts, said hollow switch body having a plurality of integral detents, and the contact mounting member having an integral detent engaging arm positioned for engaging said detents for positioning said movable contacts with respect to said fixed contacts.
