Accessory device having integrally formed plunger

摘要

An accessory device for a circuit breaker. The device includes a housing having a top wall and a hinge portion. The device also includes a plunger arm that extends from the hinge portion to form a cantilever wherein the plunger arm includes a first surface and a sloped surface. The plunger arm is moveable between an initial position wherein the plunger arm does not activate the first and second switches located in the housing and a deflected position wherein the first and sloped surfaces simultaneously contact the first and second switches, respectively, thereby activating the first and second switches. The plunger arm also includes a plunger portion that is oriented transverse to the plunger arm. A mating surface is formed on the plunger portion that mates with a mating surface of a circuit breaker operating mechanism. Further, the housing, hinge portion, plunger arm, and plunger portion are integrally formed.

1. An accessory device for a circuit breaker, wherein the circuit breaker includes an operating mechanism having a first mating surface, comprising:
a housing having a top wall and a hinge portion wherein the housing holds at least one switch; a plunger arm extending from the hinge portion to form a cantilever wherein the plunger arm is moveable between an initial position wherein the plunger arm does not activate the at least one switch and a deflected position wherein the plunger arm contacts the at least one switch thereby activating the at least one switch, the plunger arm includes a sloped inner surface having a contact area that is downwardly sloped toward an end of the plunger arm, wherein the contact area is positioned such that the contact area contacts a switch button for activating the switch button; and a second mating surface formed on an end of the plunger arm for mating with the first mating surface wherein the housing, hinge portion and plunger arm are integrally formed.
