Patent ID: 7405645

Claim:
A thermally activated circuit interrupter comprising a housing having a trip indicator receiving aperture, a stationary electrical contact mounted in the housing, a current carrying thermostatic disc mounted in the housing having a free end defined by an edge and having a movable electrical contact mounted on the free end adapted for movement between a contacts engaged position and a contacts disengaged position, a combination latch, trip indicator and reset assembly having a pivot member with first and second arms and a pivot, a latch movable with the pivot member between a first latch position adjacent to and engageable with the edge of the free end of the thermostatic disc and a second latch position under the free end of the disc when the disc is in the tripped condition, a spring member placing a force on the pivot member urging the pivot member to move the latch toward the second latch position and a trip indicator member movable between an exposed position extending through the trip indicator aperture of the housing and a recessed position, a spring urging the trip indicator member toward the recessed position, the first arm of the pivot member having a force transfer surface to transfer force between the first arm and the trip indicator to move the trip indicator member to the exposed position upon movement of the disc to the contacts open position and the trip indicator member, upon being depressed, transferring motion to the first arm of the pivot member causing the latch to move from the second latch position to the first latch position.
