Abstract
Abstract Each of the illustrated electrical switches comprises a contactor plate which is rotatable with a carriage in a casing. The contactor plate is biased by resilient means toward a plurality of contact points mounted in one end of the casing opposite the contactor plate. One of the contact points is engageable with a plurality of recesses or undulations in the contactor plate to provide a detaining action whereby the contactor plate is detained in a plurality of angularly spaced positions. Such contact point is in electrical contact with the contactor plate in each of such positions. The contactor plate also has contact segments which are engageable with other contact points as the contactor is rotated. In one embodiment, a pull pin or other stop member is removably mounted in the casing to hold the contactor plate away from one or more contact points in at least one position of the switch. The contactor may have recessed members or undulations which are opposite such contact points. The removal of the stop member releases the contactor plate for movement by the resilient means so as to bring the recessed members into engagement with the contact points. The removable pull pin or stop member may be employed as as a safety feature on a snowmobile or other vehicle whereby the pull pin may be connected by means of a cord or the like to the body or clothing of the rider so that the pull pin will be pulled out of the switch if the rider falls off the vehicle. The resulting closure of the switch may be employed to stop the engine of the vehicle.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
197 words
An electrical switch, comprising a casing, a carriage rotatably mounted in said casing, a contactor plate mounted on one end of said carriage and rotatable therewith, a plurality of contact points mounted in one end of said casing opposite said contactor plate for engagement by said plate, and resilient means biasing said contactor plate toward said contact points, said plate having a first portion conductively engaging a first one of said contact points throughout the range of movement of said contactor plate, said first portion having a plurality of angularly spaced recesses for receiving said one contact point with a detent action whereby said contactor and said carriage are detained in positions corresponding to the locations of said recesses, said one contact point and said recesses being smoothly rounded and being of corresponding size such that said one contact point is snugly receivable in each of said recesses with a precise positioning action, said contactor plate having a contact segment for engaging a second of said contact points in at least one of said positions, said contactor plate forming a closed electrical circuit between said first and second contact points in at least one of said positions.
Claim 2
Dependent Claim
197 words
