Abstract
An electrical switch assembly includes a first contact supported for movement into and out of electrical connection with a second contact. A cam assembly is configured to deflect a spring into a stressed condition, and to move the first contact into electrical connection with the second contact under a bias of the spring upon return deflection of the spring from the stressed condition. A motor has an output member. A linkage interconnects the output member with the cam assembly to deflect the spring into the stressed condition in response to movement of the output member.
Claims9
An apparatus comprising:
- an electrical switch assembly including a first contact supported for movement into and out of electrical connection with a second contact;
- a spring;
- a cam assembly configured to deflect the spring into a stressed condition, and to move the first contact into electrical connection with the second contact under a bias of the spring upon return deflection of the spring from the stressed condition;
- a motor having an output member;
- a linkage interconnecting the output member with the cam assembly to deflect the spring into the stressed condition in response to movement of the output member;
- and
- a frame having a rectangular periphery defined by a side section, an opposite side section, an end section, an opposite end section, and four corners where the side sections meet the end sections;
- wherein the motor is mounted on the side section of the frame for movement pivotally relative to the frame;
- the cam assembly and the spring are mounted on the opposite side section of the frame for movement pivotally relative to the frame;
- and
- the linkage includes a pivotal link anchored to an end section of the frame between the side sections.
