Abstract

The pushbutton switch consists of a box shaped housing divided into two chambers. The elements of the switch are mounted in the two chambers. The support for the cover contains part of a diaphragm. The switch is used for the water supply in domestic appliances such as the drain in washing machines. The pressure in the appliance acts on the diaphragm which will actuate the switch for performing the various functions of the programme. Each switch element (15) has a support (29) attached to the cover (24) of the housing. The top of the housing (11) is circular and the partitioning wall (12) divides the two chambers (13, 14) vertically. The switching elements (15) are spring loaded and are adjustable by means of a screw (18). There is a dish shaped plate (20) attached to the semi-circular section (21) of the diaphragm (22).
