A surgical instrument includes a switch base, a power bus coupled to the switch base, an electrical lead coupled to the power bus, an actuator operatively engaged with the power bus, an actuator operatively engaged with the power bus, a membrane, and a housing. The switch base has top, bottom, and side surfaces. The membrane is disposed over the top surface of the switch base and over the power bus to seal the top surface of the switch base. The housing defines proximal and distal ends and a switch base cavity between the proximal and distal ends. The housing includes bulkheads that form a plurality of fluid impermeable seals that are disposed adjacent one of the proximal and distal ends. The fluid impermeable seals are configured to deter fluid from penetrating a proximal portion of the switch base cavity within which the electrical lead is coupled to the power bus.

A push-button switch (1) comprising: a command button (12, 25, 27) and a sliding guide adapted to allow the button to slide in a sliding direction; a first tubular casing (2) having side walls (6-9) adapted to define an inner compartment (3) containing the sliding guide, the first casing (2) being fitted with a counter frame (21) and a coupling collar (3) made in one piece with said casing; a plurality of fast wiring interconnection terminals; a second casing (42) coupled to the first casing (2) and partially engaged inside the coupling collar (33), the second casing (42) housing and supporting said plurality of terminals and being fitted with a plurality of through wiring apertures (41) adapted to be crossed by electric conductors for the wiring of the switch (1); an anti-dust protection device (50) comprising a gasket (5) positioned between the counter-frame (21) and the second casing (42) to isolate the inner compartment (3) from dust infiltration paths defined between the coupling collar and the second casing (42).
摘要:
Die Erfindung betrifft einen elektrischen Schalter mit einem Gehäuse (2), wobei sich im Inneren des Gehäuses (2) ein Kontaktsystem befindet. Am Gehäuse (2) ist ein bewegbares Betätigungsorgan (4), insbesondere in der Art einer Wippe, zum schaltenden Einwirken auf das Kontaktsystem angeordnet. Für das schaltende Einwirken des Betätigungsorgans (4) befindet sich eine Öffnung (5) im Gehäuse (2). Am Gehäuse (2) ist eine elastische Dichtung (6) für die Öffnung (5) befestigt. Das Betätigungsorgan (4) umfaßt ein im Inneren des Gehäuses (2) befindliches, bewegliches Innenteil (7), insbesondere eine verschwenkbare Innenwippe, und ein am Äußeren des Gehäuses (2) befindliches, bewegliches Außenteil (8), insbesondere eine verschwenkbare Außenwippe. Die Dichtung (6) überdeckt die Öffnung (5) vollständig. Das Außenteil (8) bewegt über die elastisch bewegliche Dichtung (6) das Innenteil (7) zur schaltenden Einwirkung auf das Kontaktsystem.
摘要:
A toggle switch has a switch cover (18), a toggle lever (20), and a one piece pre-molded seal (22). The switch cover has an opening, and the toggle lever extends through the opening into the switch cover. A neck (27) of the one piece pre-molded seal surrounds the toggle lever and provides sealing between the toggle lever and the switch cover. The one piece pre-molded seal also may have a planar portion (25) that provides sealing at an interface between the switch case and the switch cover.
摘要:
A switching device (100) includes a switch, a case (1) within which the switch is accommodated, a cylindrical hollow section (7) which is disposed on the upper surface of the case and has upper (7b) and lower (7c) openings to communicate with the inside of the case, an operation knob (6) provided to cover the upper opening of the cylindrical section such that the operation knob can swing, and an operation bar (12) penetrating through the lower opening of the cylindrical section and extending to the inside of the case so as to transmit the motion of the operation knob to the switch. A projection (7d,6e) for preventing water from entering into the case is provided on the outside surface of the cylindrical section opposed to the inside surface of the operation knob, or on the inside surface of the operation knob. A plurality of vertically extending grooves (7h) may be formed in lieu of the above projections.
摘要:
A switch (1) which comprises a box-like body (2) which has a lateral containment portion (3) and an intermediate closure element (4) which has a through opening (5) and forms, with the lateral containment portion (3), an upper or actuation portion (6) and a lower or containment portion (7); the box-like body is associable, at its lower portion (7), with a shoe (8) which supports at least two fixed contacts (10) and at least one connector (11), which is mounted so that it can move between a first stable condition and a second stable condition and is functionally connected to an actuation element (12) provided with a respective spring element (13), which is accommodated within a containment recess (14), and is functionally connected to the connector (11) and has, on the opposite side with respect to the containment recess (14), an abutment body (15) which is accommodated substantially at the through opening (5); means are also provided for forming a seal between the abutment body and the intermediate closure element (4), and the abutment body (15) has a receptacle (17) for a pin (18) supported by a key (19). The sealing means comprise a sealing element (100), which protrudes from the edge of the through opening and is elastically deformable in order to press against the abutment body.
