ELECTRICAL SWITCH SYSTEM AND ELECTRICAL SWITCH ASSEMBLY

摘要

An electrical switch assembly (100) includes first and second stationary contacts (126) that are spaced apart from each other, and a switch mechanism (128). The switch mechanism comprises first and second movable contacts (134), an operational cam (404), and first and second contact frames (406, 408). The operational cam is coupled between the ends of a main shaft (402), is adapted to receive an input force in one of a first direction or a second direction, and is configured, in response thereto, to rotate the main shaft in one of a first rotational direction or a second rotational direction, respectively. The first and second contact frames are responsive to rotation of the main shaft in the first rotational direction or the second rotational direction to translate in a first translational direction or a second translational direction, respectively, to thereby move the first and second movable contacts toward or away from the first and second stationary contacts.
