ABSTRACT:
A fluid level switch for a machine having a fluid reservoir adapted to contain a fluid at an acceptable level. The fluid level switch includes a mounting plate, a float housing, and a float assembly positioned within the float housing. The mounting plate retains first and second contacts. The float housing is configured to receive fluid from the fluid reservoir and the float assembly is movable in response to the level of fluid in the float housing. The float assembly includes a contact member electrically connecting the first and second contacts when the level of the fluid is below the acceptable level. The contact member is coupled to the float for movement with the float and for movement relative to the float.
