Abstract

960,389. Switches held set and freed mechanically; retractive switches; key-operated switches. HOOVER Ltd. Oct. 10, 1960 [Oct. 13, 1959], No. 34737/59. Heading H2B. A selector switch for an automatic washing machine comprises a number of pairs of contacts 66 of which selected pairs are to be actuated by an elongated operating member 63 capable of longitudinal insertion and withdrawal from the slot 61 of the switch. The operating member has a longitudinally extending row of projections 69 arranged to actuate tappets 65 and maintain the selected contacts open. Contacts 72 may be temporarily closed by inward pres. sure on member 63 causing it to move beyond the position shown, to which it is retracted by a spring-urged plunger 71, co-operating with a notch 70, when the pressure is removed. The member 63 may have projections on both edges to provide two possible programmes (Fig. 5, not shown) or the tappets may be arranged half on each side of the switch to provide a shorter construction (Figs. 3 and 4, not shown). In another embodiment (Figs. 6 and 7, not shown) the operating member is hexagonal in section and the six sides of its head each indicate the programme selected by insertion of the member with the respective side uppermost. Specification 946,666 is referred to.
