摘要： A switch for a washing lid or the like has a collapsing operator. Over travel in the adjustment of the switch with the first lid closure is prevented by the incorporation of a deformable dampening element fitting within the collapsible portion of the operator.

摘要： A clog resistant pump for washwater employs two water flow circuits. The first powered by a conventional motor-driven pump uses filtered washwater and drives a jet-pump discharging unfiltered washwater from the washing machine. The intake or discharged water from the jet-pump is used to operate a self-cleaning filter providing water for the first circuit of the motor-driven pump. The position of the filter in the stream of wastewater and adjustment of the filter apertures in size and area reduce clogging yet allow sufficiently filtered water to permit a conventional high efficiency motor-driven pump to be used in the first stage.
