Manual starter with low voltage release

In an electric switch, the combination comprising:

• an insulating base having a rear wall, a cavity extending forwardly in the rear wall, a plurality of pairs of stationary contacts mounted on a front wall of the base with one of the contacts of each pair connected through a terminal member on the base to a voltage source, a movable contact assembly including a movable contact carrier and a plurality of movable contacts positioned by the carrier so each of the movable contacts bridgedly engages a pair of stationary contacts when the carrier is at an actuated position and is separated from the stationary contacts when the carrier is at a de-activated position, a toggle mechanism including a toggle lever, an operating lever and a trip lever pivotally mounted so the carrier is engaged and moved by the toggle lever to its actuated position when the trip lever is at a RESET position and the operating lever is moved from an OFF position to an ON position and the carrier moves to its deactivated position when the trip lever is at a tripped position, said operating lever and trip lever having inter-engaging portions for causing the trip lever to be moved from the tripped position to the RESSET position as the operating lever is moved to the OFF position, a spring constantly biasing the trip lever toward its tripped position and means for releasably maintaining the trip lever against the bias of the spring at the RESET position when the trip lever is moved by the operating lever to the RESET position, said means for releasably maintaining the trip lever at the RESET position including:
• a rotatable lever having a first portion engaging a portion on the trip lever for maintaining the trip lever at the RESET position when the rotatable lever is at a RESET position, a linearly movable slider having a first end engaging and a second portion on the rotatable lever for moving the rotatable lever to a tripped position whereat the first portion is disengaged from the engaging portion on the trip lever when the slider is moved to a tripped position and portions on the first end of the slider engageable by portions on the operating lever for moving the slider from the tripped position to a RESET position when the operating lever is moved to the OFF position, a pivotal lever having a portion engaging a second end of the slider for moving the slider to the tripped position when the pivotal lever is moved to a tripped position and moved by the slider to a RESET position when the slider is moved to the RESET position, and means including a solenoid, a spring biased lever and a latch member positioned within the cavity for causing the pivotal lever to move to the tripped position in event of power failure of the source.
