Abstract
A pump assembly having a hermetically sealed switch cavity for retaining a magnetically actuated mechanical switch. The assembly includes a housing having a motor cavity and an integral guide for cooperating with an external float assembly. A housing cover includes electrically conductive pins extending therethrough and is connected to the housing to substantially seal the motor cavity. A switch cover cooperatively engages a portion of the housing cover to form the hermetically sealed switch cavity. The switch cavity also encloses at least one conductive pin in the housing cover.
