Abstract
Abstract An interlock type switch in which mating housing portions define a closed interior chamber and clamp projecting terminals. A contact member within the chamber is adapted to bridge the terminals which perform dually as terminals and contacts. An actuator has a sliding mount in one of the housing portions and is externally accessible to raise and lower the contact member. Integrated stud means hold the housing portions in an assembled relation and fix the terminals therein.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
185 words
A switch, including opposing molded plastic housing portions defining therebetween a closed interior chamber, a pair of terminals confined between said housing portions in a spaced apart relation and having portions projecting into said chamber, an actuator slidable in one of said housing portions, and means reciprocable in said chamber responsive to movements of said actuator to occupy positions in bridging and non-bridging relation to said terminal portions, said terminals and said last named means constituting switch contacts, the other one of said housing portions having an inner face, a portion of said inner face being recessed, said other housing portion having a cavity opening into said recessed portion of said inner face, said one housing portion being applied in said recess in a closing relation to said cavity and defining therewith said interior chamber, said terminals having ends received in said recess on respectively opposite sides of said cavity and confined in said recess by said one housing portiOn, said recess being open along at least portions of the side edge of said other housing to have other ends of said terminals project therefrom.
Claim 2
Dependent Claim
185 words
A switch, including opposing molded plastic housing portions defining therebetween a closed interior chamber, a pair of terminals confined between said housing portions in a spaced apart relation and having portions projecting into said chamber, an actuator slidable in one of said housing portions, and means reciprocable in said chamber responsive to movements of said actuator to occupy positions in bridging and non-bridging relation to said terminal portions, said terminals and said last named means constituting switch contacts, the other one of said housing portions having an inner face, a portion of said inner face being recessed, said other housing portion having a cavity opening into said recessed portion of said inner face, said one housing portion being applied in said recess in a closing relation to said cavity and defining therewith said interior chamber, said terminals having ends received in said recess on respectively opposite sides of said cavity and confined in said recess by said one housing portiOn, said recess being open along at least portions of the side edge of said other housing to have other ends of said terminals project therefrom.
Claim 3
Dependent Claim
48 words
A switch according to claim 1, wherein said one housing portion has a bearing portion aligned with said cavity, said actuator having a sliding mount in said bearing portion with opposite ends projecting respectively into said cavity and outside the switch housing as defined by said housing portions.
Claim 4
Dependent Claim
51 words
A switch according to claim 2, wherein said terminals are blade-like elements adjacent edges of which project laterally to overlap peripheral portions of said cavity, said bearing portion of said one housing portion being presented in supporting relation to said adjacent edges and an inner end of said actuator passing therebetween.
Claim 5
Dependent Claim
46 words
A switch according to claim 3, characterized in that said reciprocable means is a washer-like element mounted to said inner end of said actuator and adapted to seat on said adjacent edges of said terminal, an inward thrusting motion of said actuator unseating said washer-like element.
Claim 6
Dependent Claim
158 words
A switch, including opposing molded plastic housing portions defining therebetween a closed interior chamber, a pair of terminals confined between said housing portions in a spaced apart relation and having portions projecting into said chamber, an actuator slidable in one of said housing portions, and means reciprocable in said chamber responsive to movements of said actuator to occupy positions in bridging and non-bridging relation to said terminal portions, said terminals and said last named means constituting switch contacts, the other one of said housing portions being formed as an inverted cup with laterally extending wing portions in rimming relation to said cup, said wing portions providing a recessed seat for said one housing portion, said one housing portion forming with said cup said interior chamber, and stud means formed integrally with said other housing portion and projecting through apertures in said one housing portion to establish and maintain an assembled relation of said housing portions and said terminals.
Claim 7
Dependent Claim
158 words
A switch, including opposing molded plastic housing portions defining therebetween a closed interior chamber, a pair of terminals confined between said housing portions in a spaced apart relation and having portions projecting into said chamber, an actuator slidable in one of said housing portions, and means reciprocable in said chamber responsive to movements of said actuator to occupy positions in bridging and non-bridging relation to said terminal portions, said terminals and said last named means constituting switch contacts, the other one of said housing portions being formed as an inverted cup with laterally extending wing portions in rimming relation to said cup, said wing portions providing a recessed seat for said one housing portion, said one housing portion forming with said cup said interior chamber, and stud means formed integrally with said other housing portion and projecting through apertures in said one housing portion to establish and maintain an assembled relation of said housing portions and said terminals.
Claim 8
Dependent Claim
37 words
A switch according to claim 5, wherein said terminals are blade-like elements inner ends of which are received between said housing portions, said inner ends of said terminals being fixed by passage of said stud means therethrough.
Claim 9
Dependent Claim
71 words
A switch according to claim 6, wherein the said wing portions on the other one of said housing portions form a plate portion, said inverted cup having an outer wall surface substantially coincident at one point with one edge of said plate portion and including an arcuate segment producing a projection at the opposite edge of said plate, said arcuate segment being formed with notches accommodating projection therethrough of said terminals.
