ABSTRACT:
The electrical switch which may be of a type having a toggle mechanism or a buckling mechanism for achieving abrupt motion of its movable piece. The switch is additionally provided with a mechanism for forcibly disengaging a movable contact formed on the movable piece away from a fixed contact even when the movable contact and the fixed contact are welded together due to heat generated from the contacts. This mechanism may conveniently include a pair of rack gears and a pinion gear so that the force applied to the switch is also transmitted to the disengagement mechanism for, in addition to normal switching action, pulling the movable contact away from the fixed contact. The disengagement mechanism may also be formed of other structure, but a favorable result will be obtained if the disengagement mechanism acts upon a middle portion of the movable piece as far away as possible from the contacts because the heat from the contacts may deform the working end of the disengagement mechanisms which is typically made of synthetic resin.
