Abstract
Abstract A pushbutton switch in which the pushbutton, when pushed, will alternate between an outer position and an inner position, the structure for effecting this movement exerting a minimal frictional force on the pushbutton of the switch as it moves from one operative position to the other and being so arranged as not to take up any more space than the switch proper. A heart-shaped channel is formed on an inner wall of the pushbutton body, a driving member is carried by the push rod and has a part received in that channel so as to operatively coact therewith, and a spring is mounted on an end of the switch body so as to engage and slide over the driving member as the pushbutton moves while at the same time urging the driving member against the push rod. Preferably the push rod is provided with a channel within which the driving member is received, thereby to further minimize the space taken up by the operating parts.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
168 words
A pushbutton switch comprising a body with a surface, a generally heart-shaped channel in said surface, a push rod located opposite and movable along said surface between first and second operative positions, a driving member carried by said push rod and having a part received in said channel, said biasing means active on said push rod to urge it to said first operative position, said heart-shaped channel having the point of the heart pointing generally in the direction from said second to said first operatve position, in which said driving member is mounted on said push rod so as to be movable relative to said push rod in a direction substantially perpendicular to the direction of movement of said push rod while being movable with said push rod in the direction of movement of the latter, and in which said push rod is provided with a recess facing said body surface, said driving member being received in and said part of said driving member extending beyond said recess.
Claim 2
Dependent Claim
168 words
A pushbutton switch comprising a body with a surface, a generally heart-shaped channel in said surface, a push rod located opposite and movable along said surface between first and second operative positions, a driving member carried by said push rod and having a part received in said channel, said biasing means active on said push rod to urge it to said first operative position, said heart-shaped channel having the point of the heart pointing generally in the direction from said second to said first operatve position, in which said driving member is mounted on said push rod so as to be movable relative to said push rod in a direction substantially perpendicular to the direction of movement of said push rod while being movable with said push rod in the direction of movement of the latter, and in which said push rod is provided with a recess facing said body surface, said driving member being received in and said part of said driving member extending beyond said recess.
Claim 3
Dependent Claim
53 words

Claim 8
Dependent Claim
201 words
A pushbutton switch comprising a body with a surface, a generally heart-shaped channel in said surface, a push rod located opposite and movable along said surface between first and second operative positions, a driving member carried by said push rod and having a part received in said channel, and biasing means active on said push rod to urge it to said first operative position, said heart-shaped channel having the point of the heart pointing generally in the direction from said second to said first operative position, in which said driving member is mounted on said push rod so as to be movable relative to said push rod in a direction substantially perpendicular to the direction of movement of said push rod while being movable with said push rod in the direction of movement of the latter, and in which said driving member comprises a body extending along said push rod, said part extending up from said body, and a second part extending down from said body, said push rod having an opening into which said second part of said driving member is pivotally received, and second biasing means active on said driving member to urge it away from said body surface.
Claim 9
Dependent Claim
201 words
A pushbutton switch comprising a body with a surface, a generally heart-shaped channel in said surface, a push rod located opposite and movable along said surface between first and second operative positions, a driving member carried by said push rod and having a part received in said channel, and biasing means active on said push rod to urge it to said first operative position, said heart-shaped channel having the point of the heart pointing generally in the direction from said second to said first operative position, in which said driving member is mounted on said push rod so as to be movable relative to said push rod in a direction substantially perpendicular to the direction of movement of said push rod while being movable with said push rod in the direction of movement of the latter, and in which said driving member comprises a body extending along said push rod, said part extending up from said body, and a second part extending down from said body, said push rod having an opening into which said second part of said driving member is pivotally received, and second biasing means active on said driving member to urge it away from said body surface.
