Abstract

1298230 Latching and unlatching switches TELEMECCANICA ELETTRICA OFFICINE MECCANICHE RIUNITE SpA 19 Dec 1969 [21 Dec 1968] 61997/69 Addition to 1262391 Heading H1N In an electric switch pushbutton assembly as claimed in claim 1 of the main Patent the pushbutton 2 is in two parts 21, 22 which can carry out a relative rotation but not. a relative axial sliding, part 21 being a true slider and part 22 being a key block (rotated by key 30), which, together with a flange 23 for transmitting the inward movement to a contact element, forms two transverse slits 10 for engagement by locking means 11, Figs. 2, 3, 4 (not shown), and for subsequent disengagement by rotation of key block 22, the spring tending to restore the pushbutton 2, to its original angular position being constituted by two springs 27, 28, spring 27 being a retractive spring and spring 28 rotating block 22 to its original position.
