Abstract
A float switch construction for monitoring liquid levels, comprising a float housing having a float member which is movable therein between raised and lowered positions. In the housing there is a fixed contact member and an asymmetric, elongate movable contact member, the latter having a laterally offset portion constituting a gravity-responsive mass. The housing has an electrically conductive bearing which mounts the movable contact member for both turning and pivotal movement and for conducting current to or from it. The float member and movable contact member are freely turnable with respect to one another, and have cooperable engaging portions for causing the movable contact member to pivot in response to movement of the float member. The fixed contact member has contact portions disposed annularly for engagement by the movable contact member in response to its pivotal movement irrespective of the angular orientation of the float housing. Engagement of the contact members controls a circuit from the fixed contact member to the bearing.
