Patent ID: 7190246

Claim:
An apparatus, comprising: a circuit board having an outer periphery, first and second opposite sides, and an opening within the outer periphery that extends through the circuit board; a magnetic relay device mounted on the first side of the circuit board and having a relay surface aligned with the opening; a stationary contact on the second side of the circuit board; an armature assembly including an armature surface and an armature contact, and being mounted on the second side of the circuit board for movement pivotally into and out of an engaged position in which the armature contact engages the stationary contact and the armature surface engages the relay surface, a relay frame mounted on the first side of the circuit board and configured to secure the magnetic relay device in position on the first side of the circuit board, the relay frame including a fulcrum extension that penetrates through the circuit board and upon which the armature assembly is pivotally mounted on the second side of the circuit board, a spring for biasing the armature assembly pivotally out of the engaged position, and an arc shield mounted on the second side of the circuit board and proximate to the armature contact, the arc shield further comprising a shield extension positioned relative to the armature contact to limit the displacement of the armature contact from the stationary contact when the armature assembly is moved pivotally out of the engaged position under the bias of the spring.
