Abstract
A sump pump switch for controlling the application of power from a power source to a sump pump motor in response to the rise and fall of a liquid collecting in a sump includes a housing, a pair of electrically conductive terminal members fixedly disposed within the housing and a pair of electrically conductive contact members fixedly disposed within the housing. A pair of electrically conductive movable contacts are mounted onto a contact bridge. The contact bridge is pivotally disposed within the housing and is actuated by an over-center mechanism. The movable contacts are pivotally coupled to the terminal members and selectively contact the contact members to effectively close the switch. A pair of electrically conductive wiper contacts connect the terminal members with the contact members and provide a non-articulating current path between the terminal members and the contact members.
