ABSTRACT:
The reed contact unit comprises a pair of aligned members of magnetizable and electrically conductive material spaced apart endwise from each other with a fillet of non-magnetic electrically conductive material inserted between the spaced ends of the members. The upper surfaces of the members and the fillet are coplanar. An electrically conductive cantilever carries an electrically conductive and magnetizable armature at its free end overlying the fillet and the adjacent ends of the members. Upon magnetization of the members, a contact surface of the armature contacts the members to complete an electric circuit between the cantilever and the members. The members and the cantilever are mounted within a hermetically sealed enclosure.
