Manual reset electrical equipment protector apparatus

A manual reset circuit protector comprising:

• a first housing member defining a switch cavity and having a wall mounting thereon a stationary electrical contact, the wall having a reset housing aperture formed therethrough,
• a second housing member attached to the first housing member, the second housing member mounting thereon a movable contact assembly, the movable contact assembly comprising a snap acting, cantilever mounted thermostatic disc, the disc having a free distal end, a movable electrical contact mounted on the free distal end adapted to move into and out of engagement with the stationary electrical contact,
• respective electrical terminals electrically connected to the stationary and movable electrical contacts,
• a manual reset assembly comprising a third housing member attached to the wall of the first housing member in alignment with the reset housing aperture, the third housing member having an opening formed therethrough in communication with the reset housing aperture, a slide member mounted on the third housing member within the switch cavity for rectilinear movement toward and away from the stationary electrical contact, the slide member having a follower surface extending into the opening in the third housing member, a push button disposed in the opening in the third housing member and movable in a direction in and out of the opening, the push button having a cam surface receivable on the follower surface and spring means for biasing the slide member toward the stationary electrical contact, the slide member being movable between a first retracted position away from the movable stationary contact when the push button is depressed into the opening by means of the cam member co-acting with the follower surface to push the slide member against the bias of the spring and a second protracted position adjacent the stationary electrical contact and in alignment with the movable electrical contact when the snap acting disc can snap to an open contact position allowing the slide to move in response to the bias of the spring, the slide member when in the protracted position limiting movement of the movable electrical contact when the disc attempts to snap back to the contacts engage position.
