Electrical switch construction having armature latch

摘要

An electrical switch construction having a frame carrying a movable switch blade and a latch structure for latching the switch blade in one position when the latch structure is latched and for causing the switch blade to be in another position when the latch structure is unlatched, the latch structure comprising an armature movably carried by the frame and a cam movably carried by the frame and being operatively associated with the switch blade to hold the switch blade in the one position thereof when the cam is latched by the armature being in a latching position thereof and being moved to an unlatching position from the cam when the armature is actuated by an electromagnetic actuator. The armature comprises two members secured together, one of the members being formed of plastic material and having a hook end for latching with the cam and the other of the members being formed of metal to be magnetically attracted by the actuator.
