Abstract (en)
The appts. is for a pushbutton (12) movable in the axial direction which consists of a sleeve (12A) and a threaded rod (12B) which is urged out of it by the spring (44) bearing upon the hood of the mechanism (11). The cap (15) of the pushbutton is mounted movably on a plate (14) at least partially surrounding the support (13) to which the mechanism is fixed. The sleeve is immobilised against rotation and has an internal bore into which the rod is screwed. The threads are of large pitch equal to about 2.5 times the diameter of the rod, and have an isosceles trapezoidal profile with edges at an angle of about 100 degrees to each other.
Abstract (fr)
Il s'agit d'un appareil électrique comportant un mécanisme (11) auquel il est associé, pour sa commande, un poussoir (12) globalement monté mobile axialement et formé de deux pièces en relation de vissage l'une avec l'autre, à savoir un manchon (12A) et une tige filetée (12B). Suivant l'invention, la tige filetée (12B) est soumise à des moyens élastiques de rappel (44) tendant en permanence à l'extraire du manchon (12A), et les filets (43) qu'elle comporte sont des filets à grand pas. Application, notamment, aux interrupteurs électroniques. <IMAGE>
