Abstract

Simplicity and reliability in a trip mechanism for an overload relay is achieved in a construction including a housing containing a bistable armature mounted on a pivot for movement between two stable positions. Fixed contacts are located within the housing and moveable contacts are carried by the armature for movement to a closed position with the fixed contacts for one of the two stable positions and for movement to an open position relative to the fixed contacts for the other of the two stable positions. A latch arm is carried by the armature and has a latch surface thereon. A torsion spring is mounted on the housing and has a latch finger for engaging the latch surface and retaining the armature in one of the two positions. A push button is provided for disabling the latch finger.
