Abstract

Abstract A dual switching device is provided with a pair of switches individually actuatable by a tripedal actuating level rockable about either one of a pair of plungers by the other, each switch being actuated mutually exclusive of the other by a respective plunger, neither switch being actuated by both plungers operating in mutual conjunction.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 155 words
A dual switching device comprising a support member, a first actuating plunger mounted on said support member, a second actuating plunger mounted on said support member spaced apart from said first actuating plunger, said plungers being capable of the same maximum travel upon separate or collective actuation, a first transferable switch member mounted on said support member adjacent and associated with said first actuating plunger, a second transferable switch member mounted on said support member adjacent and associated with said second actuating plunger, and control means operatively coupling said first and said second actuating plungers, said control means being separately responsive to the actuating movement of either said first or said second actuating plungers to effectively and separately transfer their said associated transferable switch members and being also collectively responsive to the actuating movement of both of said actuating plungers throughout their entire travel to prevent the transfer of either of said transferable switch members.
Claim 2
Dependent Claim 155 words
A dual switching device comprising a support member, a first actuating plunger mounted on said support member, a second actuating plunger mounted on said support member spaced apart from said first actuating plunger, said plungers being capable of the same maximum travel upon separate or collective actuation, a first transferable switch member mounted on said support member adjacent and associated with said first actuating plunger, a second transferable switch member mounted on said support member adjacent and associated with said second actuating plunger, and control means operatively coupling said first and said second actuating plungers, said control means being separately responsive to the actuating movement of either said first or said second actuating plungers to effectively and separately transfer their said associated transferable switch members and being also collectively responsive to the actuating movement of both of said actuating plungers throughout their entire travel to prevent the transfer of either of said transferable switch members.
Claim 3
Dependent Claim 82 words
The dual switching device as defined by claim 1 wherein said control means comprises an actuating member of tripedal configuration and resilient means effectively biasing said actuating member into contact with said first and said second actuating plungers. The dual switching device defined in claim 2 wherein said resilient means comprises a spring connected to a central point along the linear dimension of said actuating member and to said support member at a point intermediate said first and said second actuating plungers.
Claim 4
Dependent Claim 55 words
The dual switching device as defined by claim 3 wherein said actuating member comprises a first and a second arm effectively contacting said first and said second actuating plungers and a third arm extending perpendicularly to said first and said second arms and in interposed relationship between said first and said second transferable switch members.
Claim 5
Dependent Claim 28 words
The dual switching device as defined by claim 4 wherein said actuating member is linearly translatable in response to the collective actuation of both of said actuating plungers.
Claim 6
Dependent Claim 32 words
The dual switching device as defined by claim 5 wherein said actuating member is rockably translatable in response to the separate actuation of either of said first or said second actuating plungers.
Claim 7
Dependent Claim 41 words
The dual switching device as defined by claim 6 wherein said third arm of said actuating member selectively actuates one of said transferable switch members upon said rockable translation of said actuating member by a respective one of said actuating plungers.
Claim 8
Dependent Claim 84 words
The dual switching device as defined by claim 7 and additionally comprising a first collet disposed approximate one end of said first actuating plunger and a second collet disposed approximate one end of said second actuating plunger, said first collet in cooperation with said resilient means effectively coupling said first arm of said actuating member with said first actuating plunger and said second collet in cooperation with said resilient means effectively coupling said second arm of said actuating member with said second actuating plunger.
