Motorized electrical switch mechanism

摘要

A bistable relay may include a pair of contact arms. Each contact arm is configured to have a first end and a second end, such that, when the relay is in the closed position, current flows from the first end to the second ends of each of the contact arms, and when the relay is in an open position, current does not flow from the first ends to the second ends of the contact arms. The relay further includes a motor, a pair of springs, a pair of cams driven by the motor, and a linearly actuating member configured to move the contact arms from the first configuration to the second configuration, the member including a cam follower surface.
