Abstract
An electromagnetic relay includes a relay coil assembly, an armature, and a contact system. The contact system includes a stationary contact assembly stationary contacts and moveable contact springs adjacent to the stationary contacts. The moveable contact springs have a projecting portion. The armature is 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. The stationary contact assembly includes an overmold portion attached to the at least one stationary contact. The overmold portion includes a dielectric material and is 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.
