Abstract
A switch for an electrical circuit includes a base, a rotatable cam having a first profile and a second profile, a solenoid, a link, and a member comprising a cam follower configured to follow the second profile. A first cycle of the solenoid includes a first energized state and a first de-energized state and the second cycle of the solenoid includes a second energized state and a second de-energized state. A first portion of the link couples to the solenoid, and a second portion of the link movably couples to the first profile of the cam. When the solenoid is in a first cycle, the member moves from a retracted position to an extended position, and when the solenoid is in a second cycle, the member moves from the extended position to the retracted position.

A switch for an electrical circuit, comprising:
- a base;
- a cam pivotally coupled to the base and having a first cam profile and a second cam profile;
- a solenoid operating in alternating first and second cycles, the first cycle including a first energized state and a first de-energized state and the second cycle including a second energized state and a second de-energized state;
- a link having a first portion coupled to the solenoid, and a second portion having a cam follower to follow the first cam profile;
- and
- a member configured to move with respect to the base between a first position and a second position, said member having a cam follower configured to follow the second cam profile by movement of said cam;
- when the solenoid operates in the first cycle, the cam follower of the link rotates the cam from a first position to a second position and the cam moves the cam follower of the member and moves the member from the second position to the first position, and when the solenoid operates in the second cycle, the cam follower of the member moves the member from the second position to the first position.
A switch for an electrical circuit, comprising:
- a solenoid comprising alternating energized and de-energized states;
- a cam having a first cam profile and a second cam profile;
- a link having a first portion coupled to the solenoid, and a second portion with a cam follower operatively connected to the cam to follow the first cam profile and to move said cam between a first position and a second position;
- and
- a member configured to move between an extended position and a retracted position and having a cam follower configured to follow the second profile;
- wherein the cam is configured such that alternating energized states of the solenoid cause opposite motion of the member.
A switch, comprising:
- a solenoid having a plunger for moving between a first position and a second position, and configured for operating in a first energized state, a first de-energized state, a second energized state and a second de-energized state;
- a cam movable between a first position and a second position, said cam having a first cam profile and a second cam profile;
- a link having a first portion coupled to said plunger and a second portion with a cam follower coupled to said first cam profile of said cam to pivot said cam between said first position and second position;
- a movable member having a cam follower operatively connected to said second cam profile to move said member between a first retracted position and a second extended position by movement of said cam member;
- where the solenoid operates in a first cycle to move said plunger from said first position to said second position, and from said second position to said first position, and where said first cycle moves said cam from said first position to said second position and moves said member from said first position to said second position.
