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.
Claims21
A switch for an electrical circuit, comprising:
- a base;
- a cam rotatably coupled to the base and defining a first profile and a second profile, the first profile including a first position, a second position, a third position, and a fourth position;
- a solenoid comprising 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 including a first portion and a second portion, the first portion coupled to the solenoid, the second portion movably coupled to the first profile of the cam;
- and
- a member configured to move in a linear direction between an extended position and a retracted position and comprising a cam follower configured to follow the second profile;
- wherein when the solenoid is in the first cycle, the member moves from the retracted position to the extended position, and wherein when the solenoid is in the second cycle, the member moves from the extend position to the retracted position.
A switch for an electrical circuit, comprising:
- a solenoid comprising alternating energized and de-energized states;
- a cam defining a first profile and a second profile;
- a link including a first portion and a second portion, the first portion coupled to the solenoid, the second portion movably coupled to the cam to follow the first profile;
- and
- a member configured to move in a linear direction between an extended position and a retracted position and comprising a cam follower configured to follow the second profile;
- wherein the cam is configured such that alternating energized states of the solenoid cause opposite linear motion of the member.
A latching system, comprising:
- a solenoid comprising a first energized state, a first de-energized state, a second energized state and a second de-energized state;
- a member configured to translate in a linear direction between an extended position and a retracted position;
- and
- a mechanical linkage operatively coupling the solenoid to the member, the mechanical linkage having a first orientation and a second orientation;
- wherein the mechanical linkage is configured such that when the solenoid is in the first energized state, the member moves from the retracted position to the extended position and the mechanical linkage moves from the first orientation to the second orientation, and wherein the mechanical linkage is configured such that when the solenoid is in the second energized state, the member moves from the extended position to the retracted position and the mechanical linkage moves from the second orientation to the first orientation.
A switch comprising:
- an operating rod configured to translate in a linear direction between a first position and a second position;
- and
- a solenoid actuator and a link for moving the operating rod from the first position to the second position and from the second position to the first position, wherein the solenoid actuator includes only one solenoid for causing travel in each direction between the first position and the second position and does not require electronic controls to maintain current at the first position and the second position.
