Patent

CA 2494641

The panel mounted low profile rotary switch (170, 300) includes a knob (175, 210, 305), a detent subassembly (180, 220), a shaft (255, 365), a bushing (185, 260, 355) and a panel (197). The knob is simply held to the shaft by one or more locking screws (177) and the operation of the detent sub-assembly is not altered by removal of the knob. The entire detent sub-assembly is located on the knob side or user's side of the panel. Only the bushing and the shaft extend through the panel. The shaft is connected to a rotary component such as a rotary switch contact (265, 372) which engages circuitry on a printed circuit board (374). The switch or electrical connection is located on or juxtaposed to the undersurface of the panel

L'invention concerne un commutateur rotatif à profil bas (170, 300) monté sur un panneau comprenant une poignée (175, 210, 305), un sous-ensemble cranté (180, 220), un arbre (255, 365), une bague (185, 260, 355) et un panneau (197). La poignée est simplement maintenue sur l'arbre par une ou plusieurs vis de calage (177) et l'opération du sous-ensemble cranté n'est pas modifiée par le retrait de la poignée. Tout le sous-ensemble cranté est situé sur le côté de la poignée ou le côté de l'utilisateur du panneau. Seule la bague et l'arbre s'étendent à travers le panneau. L'arbre est connecté à un composant rotatif de sorte que le contact du commutateur rotatif (265, 372) couple les circuits à une plaquette de circuit imprimé (374). Le commutateur ou la connexion électrique est situé sur ou à proximité de la sous-surface du panneau.
