ABSTRACT:
An improved housing for a mercury float switch as disclosed in U.S. Pat. No. 4,223,190. The improved housing includes an exterior bracket connected to a side wall of the housing structured to releasably yet securely retain lead electrical wires extending from the mounting shaft of the float switch whereby the exposed lead electrical wires may be arcuately configured, then wedgedly locked between the bracket and side wall. By this arrangement, free pivotal movement of the float switch within the housing is maintained while holding the exposed lead electrical wires above the bilge water level, as in a boat bilge.
