Abstract:
1. An electromagnetic latching relay comprising: a relay coil assembly, an armature, and a contact system; the contact system including at least one stationary contact assembly comprising at least one stationary contact and at least one moveable contact spring adjacent to the at least one stationary contact, the at least one moveable contact spring having a projecting portion wherein the armature pivotably actuated in response to an electromagnetic force generated by the relay coil, to move the at least one contact spring linearly between a first position and a second position; wherein the at least one stationary contact assembly comprises an overmold portion attached to the at least one stationary contact, the overmold portion comprising a dielectric material and bonded to the at least one stationary contact to maintain a predetermined configuration of the stationary contact relative to the at least one moveable contact spring; and wherein the armature further comprises a first cam portion and a second cam portion, each of the first and second cam portions cooperative with a projecting feature of a corresponding pair of the at least one moveable contact springs to cause the respective contact springs of the projecting feature to switch to one of the first and second state.
