摘要:
The present disclosure is directed in various embodiments to membrane switches generally. More specifically, a membrane switch is provided that may be exposed to sterilization processes, including vacuum processes without damaging the switch. Thus, the inventive membrane switch comprises a gas permeable, liquid impermeable membrane layer. In various embodiments, the membrane switch may be used in rotational atherectomy systems. However, the membrane switch of the present invention has wide application beyond rotational atherectomy.

Provided is a switch which can form an airtight container easily. The switch is a switch in which a pair of fixed contacts (111 and 112) disposed at a predetermined distance from each other and a movable contact (130) arranged to be able to make/break contact with the pair of fixed contacts are internally mounted in an arc extinguishing container (102), wherein: the arc extinguishing container is formed by bonding a resin container and a metal bucket-shaped body (104) to each other by an adhesive agent, the resin container having a terminal retention plate portion (103c) which retains a pair of external connection terminals (114) as constituents of the pair of fixed contacts by adhesive bonding, and a side plate portion (103d) which extends downward from an outer circumferential portion of the terminal retention plate portion, an opposite side of the resin container to the terminal retention plate portion being formed as an open face, the bucket-shaped body being internally mounted with the pair of fixed contacts inserted into the side plate portion of the resin container and the movable contact, the bucket-shaped body having an open lower side.
摘要:
Ein Einbauschalter, insbesondere ein Türöffnerschalter, zur Montage auf einer Befestigungsfläche (50) hat ein rohrförmiges Gehäuse (14, 60) und einen, aus der Benutzungsrichtung des Türöffnerschalters gesehen, über den Deckel (14, 60) überstehenden Flansch (15) mit einer axial beweglichen Taste (10, 11) zur Betätigung eines mit dem Gehäuse (14, 60) verbundenen Schaltorgans (71). Dabei wird die Taste (10, 11) durch eine Rückstellkraft in ihrer Ruhelage gehalten und ist gegen die Wirkung dieser Rückstellkraft eindrückbar. Es ist ein Befestigungsring (20) vorgesehen, mit dem der Türöffnerschalter auf der Befestigungsfläche (50) fixierbar ist. Der Flansch (15) des Gehäuses (14, 60) überdeckt dabei den Befestigungsring (20) vollständig, und es ist ein Supportring (30) vorgesehen, mit dem der Taster (10) mit dem Befestigungsring (20) verriegelbar ist, so dass die Auslösefläche (11) der Taste (10) die Befestigungselemente (21) an dem Paneel (50) abdeckt, insbesondere also eine grössere Fläche als seine eigene Befestigungsgrundfläche überlagert.
