ABSTRACT:
A stop motion switch adapted to be in threaded engagement with an elongated filament and responsive to a break in the filament to cause the switch to go from a "first" to a "second" position (off to an on position) composed of a dielectric body and a rocker arm, the rocker arm being composed of two terminal portions, joined together by a median portion and a filament guide on at least one of the terminal portions, the longitudinal axis of the terminal portions being essentially perpendicular to the longitudinal axis of the median portion. The dielectric block contains an aperture, in which the median portion is rotatably received, a first terminal means in electrical communication with the median portion, a second terminal adapted to be connected to ground and an elongated electrical current carrying member disposed along side the dielectric body in such a fashion that upon rotation of the rocker arm the elongated electric current carrying member is adapted to come in sliding electrical and mechanical contact with one of the terminal portions of the rocker arm (on position) to complete a circuit that de-energizes a knitting machine and filament feeding machine, the sliding motion being such that the final electrical and mechanical contact of the elongated electrical current carrying with the terminal portion of the rocker arm is different from its initial contact.
