Abstract
Abstract An improved electrical snap switch which includes a housing having a base, a common terminal fixedly provided on the base, a movable piece having a movable contact secured to its one end and an inner plate formed in it to extend from its other end towards the movable contact, with the inner plate being supported, at its forward end, by the common terminal, a plate-like movable spring engaged, at its one end, with the movable piece in the vicinity of the movable contact and at its other end, with a support portion provided adjacent to a base portion of the inner plate, and an operating member engaged with the other end portion of the movable piece.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
171 words
An electrical switch comprising; a housing having a base, a common terminal fixedly mounted on and extending longitudinally of said base within said housing, a movable member having an inner plate and an outer plate, horizontal surfaces extending longitudinally of said housing, and first and second ends, a movable contact carried on said outer plate second end, wherein said inner plate extends from said first end towards said second end, wherein said inner plate is attached to said common terminal at a point which is proximate to said second end of said movable member, actuating spring means engaged at one end thereof with said movable member outer plate second end adjacent to said movable member contact and at the other end thereof to a second engaging point fixed with respect to said housing, and an operating member for reciprocally engaging said first end of said movable member, the point of engagement of said operating member with said movable member being in proximity to said fixed point with respect to said housing.
Claim 2
Dependent Claim
171 words
An electrical switch comprising; a housing having a base, a common terminal fixedly mounted on and extending longitudinally of said base within said housing, a movable member having an inner plate and an outer plate, horizontal surfaces extending longitudinally of said housing, and first and second ends, a movable contact carried on said outer plate second end, wherein said inner plate extends from said first end towards said second end, wherein said inner plate is attached to said common terminal at a point which is proximate to said second end of said movable member, actuating spring means engaged at one end thereof with said movable member outer plate second end adjacent to said movable member contact and at the other end thereof to a second engaging point fixed with respect to said housing, and an operating member for reciprocally engaging said first end of said movable member, the point of engagement of said operating member with said movable member being in proximity to said fixed point with respect to said housing.
Claim 3
Dependent Claim
39 words
An electrical switch as claimed in claim 1 further including a normally open contact and a normally closed contact respectively fixed to corresponding terminals provided on said base, so as to confront said movable contact of said movable piece.
Claim 4
Dependent Claim
37 words
An electrical switch as claimed in claim 1, wherein said operating member is a piezoelectric bimorph element associated, at its forward end, with said the other end portion of said movable piece through a drive transmitting member.
Claim 5
Dependent Claim
199 words
An electrically actuated switch comprising: a housing having a base, a common terminal fixedly mounted on and extending longitudinally of said based within said housing, a movable member having an inner plate and an outer plate, horizontal surfaces extending longitudinally of said housing and first and second ends, a movable contact carried on said outer plate second end, wherein said inner plate extends from said first end towards said second end, wherein said inner plate is attached to said common terminal at a point which is proximate to said second end of said movable member, actuating spring means engaged at one end thereof with said movable member outer plate second end adjacent to said movable member contact and at the other end thereof to a second engaging point fixed with respect to said housing, an operating member arranged orthogonally of said movable member first end for reciprocally engaging said first end of said movable member, the point of engagement of said operating member with said movable member being in proximity to said fixed point with respect to said housing, and electrically-operated actuating means for driving said operating member and arranged in said housing in parallel with said movable member.
Claim 6
Dependent Claim
199 words
An electrically actuated switch comprising: a housing having a base, a common terminal fixedly mounted on and extending longitudinally of said based within said housing, a movable member having an inner plate and an outer plate, horizontal surfaces extending longitudinally of said housing and first and second ends, a movable contact carried on said outer plate second end, wherein said inner plate extends from said first end towards said second end, wherein said inner plate is attached to said common terminal at a point which is proximate to said second end of said movable member, actuating spring means engaged at one end thereof with said movable member outer plate second end adjacent to said movable member contact and at the other end thereof to a second engaging point fixed with respect to said housing, an operating member arranged orthogonally of said movable member first end for reciprocally engaging said first end of said movable member, the point of engagement of said operating member with said movable member being in proximity to said fixed point with respect to said housing, and electrically-operated actuating means for driving said operating member and arranged in said housing in parallel with said movable member.
