Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
115 words
In a precision snap switch having a movable contact blade mounted and stressed for self movement to a normal stable position from which it is actuatable with snap action to another position, in combination, a molded insulating base having opposite sides and ends, a one piece snap blade support and terminal member secured to and straddling the opposite sides of said base at one end thereof, said member overlying a portion of said contact blade at one side of said base and providing a snap pivot fulcrum for another portion of such blade, and a one piece combination stationary contact and terminal member straddling said opposite sides of said base at the other end thereof.
Claim 2
Dependent Claim
115 words
In a precision snap switch having a movable contact blade mounted and stressed for self movement to a normal stable position from which it is actuatable with snap action to another position, in combination, a molded insulating base having opposite sides and ends, a one piece snap blade support and terminal member secured to and straddling the opposite sides of said base at one end thereof, said member overlying a portion of said contact blade at one side of said base and providing a snap pivot fulcrum for another portion of such blade, and a one piece combination stationary contact and terminal member straddling said opposite sides of said base at the other end thereof.
Claim 3
Dependent Claim
63 words
The combination according to claim 1 wherein each of said one piece members have integral bight portions overlying the respective ends of said base that connect their portions that straddle said opposite sides of said base, and wherein wire securing terminal screws are threadingly mounted in each of said one piece members on corresponding sides of said base opposite said one side thereof.
Claim 4
Dependent Claim
41 words
The combination according to claim 1 wherein said stationary contact support and terminal member has a contact supporting portion which is spaced apart from said one side of said base with which said contact blade engages when in its normal position.
Claim 5
Dependent Claim
48 words
The combination according to claim 1 together with a stop member secured to said base in spaced relations to a contact mounted on said stationary contact support and terminal member and serving to limit the movement of said contact blade when actuated out of its normal stable position.
Claim 6
Dependent Claim
82 words
The combination according to claim 1 together with a cover formed of an insulating material which has a snap-on fit with said base which it encloses on all sides except the other of said opposite sides, and an axially rotatable actuator plunger extending through openings in said cover, and said portions of said contact blade and said overlying blade support and terminal member and engaging at a flat end surface with a convex hemispherical dimple formed on said portion of said blade.
