Abstract
Double-pass pushbutton, able to act successively on one or both independent microswitches (M1), (M2), where the body-shell and the pushbutton have a leaktight and flexible cap mounted between them, which hermetically seals the joint without interfering with the guided axial movement of the pushbutton, with respect to the body to be activated, or stopping the operator's action; it has two contact stops at different heights, for their successive contact with the relative microswitches when moved linearly; and there are means between the body-shell and the pushbutton for the successive positioning of the pushbutton. For application in control pushbutton panels.
Claims5
- Double-pass pushbutton, able to act successively on one or both independent microswitches (M1), (M2), characterised because:
- a) the body-shell (1) and the pushbutton (2) have a leaktight and flexible cap (3) mounted between them, which hermetically seals the joint without interfering with the axial guided movement of the pushbutton (2) with respect to the body (1) on being activated, or stopping the operator's action;
- b) it has two contact stops (T1), (T2) at different heights, for their successive contact with the relative microswitches (M1), (M2) on moving linearly;
- c) there are means (5) between the body-shell (1) and the pushbutton (2) for the successive positioning of the pushbutton (2).
- Double-pass pushbutton, according to previous claim, characterised because the assembly of the cap (3) in the body-shell (1) and in the pushbutton button (2) takes place by elastic deformation of the former, which clamps or is housed in combined formations of the latter.
- Double-pass pushbutton, according to previous claims, characterised because the aforementioned operating means (45) are comprised of:
- a) some diametrically formed generatricial ramps (51) in the body-shell (1);
- b) a diametrical box (52) in the pushbutton (2) where several balls (53) are housed, which are maintained in counterposition by an internal spring (54), which, housed in the box (52) is aimed at maintaining the balls (53) housed in some generatricial ramps (51).
- Double-pass pushbutton, according to previous claims, characterised because the pushbutton (2) is aimed at being maintained in an extreme standby position due to the action of one or several pressure springs (4) mounted coaxially to one or both contact stops (T1), (T2).
- Double-pass pushbutton, according to previous claims, characterised because the aforementioned generatricial raps (51) are formed in an independent bushing (13) mounted on the body-shell, respect to which it stands out on the inside defining a tuck, which some perimeter projections (22) come up against, defined together in the pushbutton button (2), to prevent involuntary disassembly.
