Abstract

1,262,391. Latching and unlatching switches. TELEMECCANICA ELETTRICA OFFICINE MECCANICHE RIUNITE S.p.A. 22 May, 1969 [14 June, 1968], No. 26058/69. Heading H1N. An electric switch push-button is latched in against the action of a retractive spring automatically at the end of the inward non-rotary movement and is unlatched by partial rotation of the push-button against the action of a spring tending to restore the push-button to its original angular position. As shown, pushbutton 5 is joined to slider 2 by screw 6 and has two recesses 10, which, when push-button 5 is pushed in against the action of retractive spring 4, are engaged automatically by the two arms of a U-shaped spring 11 held in place by hexagonal plate 13 which is force-fitted into the bore of housing 1. The bottoms of the recesses 10 are curved so that when push-button 5, knurled at 7, is partially rotated the curved bottoms of recesses 10 cam the arms of spring 11 open to release slider 2. Spring 4 is fast with slider 2 at one end and fast with housing 1 at the other end so that when push-button 5 is rotated to release the latch, spring 4 is twisted to return pushbutton 5 to its original angular position upon release. Slider 2 has projections 8 which slide in channels in housing 1 to limit angular movement. The end of slider 2 has two recesses 20 which are engaged by split plate 14 to retain slider 2 in housing 1 and to operate the contacts (not shown or described). Housing 1 is fastened to panel 18 and sealing washers 3, 19 are provided.
