摘要:
A switch device (10) includes a circuit board (14) disposed in a tubular holder case (18), a control button (34) disposed for movement along the longitudinal directions of the holder case (18), the control button (34) being actuated by pressing from outside of the switch device (10), and a switch unit mounted on the circuit board (14), the switch unit being actuated in response to rearward movement of the control button (34) by pressing. A coil antenna (194) is disposed rearwardly of the control button (34) and has an outside diameter which is substantially the same as an outside diameter of the control button (34).

A double-contact control unit for electric plants, which is adapted to be anchored to a fixed or movable support element of an electric plant, comprises an insulating support (4) having a longitudinal axis (L) and a predetermined axial length (1), two pairs of fixed contacts (5, 5'; 6, 6') mounted to the support (4) in longitudinally offset positions and adapted to be connected to corresponding electric circuits associated with the plant to cooperate with respective pairs of movable contacts (13, 13'; 14, 14') for opening/closing the electric circuits, each of the fixed contacts (5, 5'; 6, 6') being associated with a respective electrical connection terminal (7, 7'; 8, 8'). The terminals (7, 7'; 8, 8') of each pair of fixed contacts (5, 5'; 6, 6') are located in symmetric positions with respect to the longitudinal axis (L), at distances and inclination angles (α) differing from those of the terminals (7, 7'; 8, 8') of the other pair of fixed contacts (5, 5'; 6, 6') and at least partially transversely aligned therewith to reduce the longitudinal offset of the pairs of fixed contacts (5, 5'; 6, 6') and the axial length (1) of the support (4).

A switch assembly is provided to actuate a pair of switches using a single key cap, e.g. for a camera that utilizes a first switch to activate an image focusing function and a second switch to activate a camera shutter. The switch assembly comprises a first switch and a second switch, wherein the first switch partially or completely surrounds the perimeter of the second switch. The first switch comprises an upper conductive surface and a lower conductive surface that, when in contact, electrically couples two terminals for closing a circuit. The second switch comprises an actuator and a dome switch. When the key cap receives a first downward force, only the first switch becomes activated and a first electric circuit is completed. When the key cap receives a second downward force that is greater than the first force, the dome switch collapses and a second electric circuit is completed.

An endoscope fluid control input device comprises an operating button (3) for effecting the switching of the kind and flow rate of a fluid supplied to a pipeline in an endoscope by push-in capacity, an urging spring (7) for restoring an operating button (3) to its predetermined position, an optical sensor (2) which causes generation of a signal corresponding to the push-in position of the operating button (3), a rubber cover (25) water-tightly covering all structural members, and a click spring (6) and a projection (3a) which cooperate with each other to produce a temporary and sharp change in capacity simultaneously with, or at a predetermined time before or after the occurrence of, a signal generated according to a change in the position of the operating button (3). And the fact that a signal has been generated from the optical sensor (2) is made known to the operator by the change in capacity brought about by the cooperation between the click spring (6) and projection (3a).

Es wird ein Umschalter zum Schalten von zwei Stromkreisen beschrieben, mit einem Gehäuse (12), einem Stößel (14), zwei Kontakten (1, 2) eines ersten Stromkreises, zwei Kontakten (3, 4) eines zweiten Stromkreises und einem Schaltkontakt (16), der im Ausgangszustand eine erste Form aufweist, in welcher der erste Stromkreis geschlossen und der zweite Stromkreis geöffnet ist, und durch Betätigung des Stößels (14) in eine zweite Form gebracht werden kann, in welcher der erste Stromkreis geöffnet und der zweite Stromkreis geschlossen ist. Diese zweipolige Umschaltung kann auch bei Kurzhubtasten und Folientastaturen angewendet werden.
摘要:
A push-button switch provided with a hollow push button (2), a case (3) supporting it, and a switching mechanism (6) having a first contact (41) disposed within the case (3) and a second contact (51) disposed opposite to the first contact (41), with one of its ends being inserted into a hole (2a) of the push button (2). Within a hole (61a) formed in an inserted section (61) of the switching mechanism (6), a slide block (8) is provided slidably in a direction crossing the direction in which the push button (2) is pushed. A slope (8a) capable of engaging with a slope (2b) of the hole (2a) of the push button (2) is formed on the slide block (8). A coil spring (return spring) (12) for energizing a shaft (62) of the switching mechanism (6) so as to abut the push button (2) is provided on the bottom (31) of the case (3). This configuration enables the push button (2) to take up a first OFF state, an ON state and a second OFF state in order of depression.
