Abstract
Abstract An electric switch in which the movable contact-carrier is in the form of a rockable lever, the ends of which are engaged by the ends of an arcuated leaf spring depressed by a U-shaped member. This rockable lever is operated by a rockable operating member which is provided with two parallel depending projections, embracing the U-shaped member and the movable contact-carrier.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
197 words
An electric switch comprising a stationary portion; fulcrum means fixed relative to said stationary portion; and arm pivotable on said fulcrum means between two positions relative to said stationary portion and having opposite surfaces; at least one pair of contacts, respectively mounted on said stationary portion and said arm, said contacts becoming closed in one of said positions of said arm; deformable spring means extending in a direction longitudinal of said arm and spaced from one surface thereof for snapping said arm from one position to the other position in response to forces applied to said spring means which deform and urge a bearing portion of said spring means in a direction transversely of said fulcrum means; an operating rocker member mounted on said stationary portion, said rocker member having at least one extension which has an end portion projecting beyond the other surface of said arm, said end portion being movable to either side of said fulcrum means during rocking of said rocker member; and engaging means engaging said extension and said spring means for deforming and urging said bearing portion of said spring means in said transverse direction in order to effect the snapping action.
Claim 2
Dependent Claim
197 words
An electric switch comprising a stationary portion; fulcrum means fixed relative to said stationary portion; and arm pivotable on said fulcrum means between two positions relative to said stationary portion and having opposite surfaces; at least one pair of contacts, respectively mounted on said stationary portion and said arm, said contacts becoming closed in one of said positions of said arm; deformable spring means extending in a direction longitudinal of said arm and spaced from one surface thereof for snapping said arm from one position to the other position in response to forces applied to said spring means which deform and urge a bearing portion of said spring means in a direction transversely of said fulcrum means; an operating rocker member mounted on said stationary portion, said rocker member having at least one extension which has an end portion projecting beyond the other surface of said arm, said end portion being movable to either side of said fulcrum means during rocking of said rocker member; and engaging means engaging said extension and said spring means for deforming and urging said bearing portion of said spring means in said transverse direction in order to effect the snapping action.
Claim 3
Dependent Claim
70 words
An electric switch as defined in claim 1, wherein said arm has two ends, each end being positioned at another side of said fulcrum means, and wherein said switch comprises two pairs of contacts, each pair being located at another end of said arm and respectively mounted on said stationary portion and said arm, whereby one pair of contacts becomes closed in each of said two positions of said arm.
Claim 4
Dependent Claim
39 words
An electric switch as defined in claim 1, wherein said arm has a pivoting portion adapted to pivot said arm on said fulcrum means, said spring means comprising a saddle-shaped spring secured at opposite ends of said pivoting portion.
Claim 5
Dependent Claim
15 words
An electric switch as defined in claim 3, wherein said spring is a leaf spring.
Claim 6
Dependent Claim
32 words
An electric switch as defined in claim 1, wherein said rocker member has a rocking axis, said extension end portion and said rocking axis being located on opposite sides of said arm.
Claim 7
Dependent Claim
47 words
An electric switch as defined in claim 1, wherein said extension end portion has a recess and wherein said engaging means comprises a rigid member having a pair of portions one of which engages said bearing portion and the other of which is located in said recess.
Claim 8
Dependent Claim
23 words
An electric switch as defined in claim 6, wherein said rigid member is movable in said recess during rocking of said rocking member.
Claim 9
Dependent Claim
83 words
An electric switch as defined in claim 6, wherein said operating rocker member has two extensions, one on each side of said spring means, said rigid member being U-shaped, forming said engaging means and consisting of a transverse portion and two legs attached to the latter, each leg having fixed thereon end portions which extend in directions substantially parallel to said transverse portion, said transverse portion being in contact with said bearing portion and said end portions respectively being engaged with said extensions.
Claim 10
Dependent Claim
28 words
An electric switch as defined in claim 1, wherein the rocking axis of said rocker member is located intermediate of said bearing portion and said extension end portion.
Claim 11
Dependent Claim
82 words
An electric switch as defined in claim 1, wherein the rocking axis of said rocking member and the fulcrum point of said fulcrum means define a plane, said bearing portion being movable to one side of the plane in response to movement of said extension end portion to said one side of the plane, said engaging means maintaining said end portion and said bearing portion in substantially fixed spaced relation to each other in opposition to the action of said spring means.
