PUSHBUTTON ELECTRIC SWITCH

摘要

A circuit interrupter characterized by a manually operated fast acting switch and an overload relay for tripping of switch in response to current overload. The switch comprises means for moving electric contacts between open and closed and tripped positions which means includes a releasable arm which is movable between latched and unlatched positions. The switch also comprises a pair of pushbuttons for manually opening and closing the switch which pushbuttons are effective to move a lever which in turn actuates an overcenter toggle mechanism for opening and closing the switch.
