Abstract: An automatic cable tie apparatus tightens and fastens a cable tie around a bundle of cables. A motor imparts rotational movement to a shaft separately in a first direction and a second direction. The first and second directions are one of a clockwise and counter-clockwise direction. A cable tie delivery mechanism is operably joined to the motor such that the cable tie delivery mechanism transfers a cable tie to a cable tie load starting position as the shaft rotates in the first direction. A transporter is also operably joined to the motor such that the transporter transfers the cable tie from the cable tie load starting position to a cable tie tensioning position as the shaft rotates in the second direction.

Abstract: An interlock switch used with an electrical appliance such as a microwave oven. The interlock switch has a housing in which a plurality of switch elements are mounted. The housing also contains movable and stationary barriers which isolate selected switch elements from others so that broken off pieces from some switch elements will not come in contact with other switch elements.

Abstract: In an interlock switch used with an electrical appliance such as a microwave oven. The interlock switch has a housing having an interior front wall, and a plurality of conductive switch elements. A pair of barriers define a pair of gaps with the interior front wall for mounting a buss, comprising a first segment, formed integrally with one of the conductive switch elements, and a second segment, formed integrally with another one of the conductive switch elements.

Abstract: An interlock switch used with an electrical appliance such as a microwave oven. The interlock switch comprises a housing having a plurality of conductive swtich elements operated by an actuator. At least two of the conductive switch elements are biased in opposite directions, thereby reducing the force that would otherwise be needed to operate the actuator.
