摘要:
There is adopted a case 2 having a curved outer appearance in an operating lever in which two rotary knobs 3, 4 are provided to be spaced therebetween. Rotation of a first rotary knob 3 is transmitted by an inner diameter-side rotation transmitting member 6 for connecting a first shaft portion 61 and a second shaft portion 63 to be capable of rotating integrally by a flexible shaft 62, and rotation of a second rotary knob 4 is transmitted by an outer diameter-side rotation transmitting member 7 for connecting a tubular part inserted outside of the first shaft portion side and a tubular member inserted outside of the second shaft portion side for rotation transmission by a rotation transmitting mechanism 8. Torsional stress causing an inner periphery of an outer spring Sp1 in the rotation transmitting mechanism 8 to make pressure contact with a tubular wall part 813 of a common holder 81 and a large-diameter tubular part of an inner holder 85 acts on the outer spring Sp1, and torsional stress causing an outer periphery of an inner spring Sp2 to make pressure contact with the tubular wall part 813 of the common holder 81 and the large-diameter tubular part of the inner holder 85 acts on the inner spring Sp2, thus connecting the inner holder 85 and an outer holder 86 to be incapable of rotating relative to each other.

There is provided a switching apparatus (1) for capable of facilitating a disconnecting operation, achieving miniaturization and preventing occurrence of sparks at the time of disconnection and connection. A switching apparatus includes a base (3), a housing (5), a main switch (9a, 9b) for mechanically disconnecting a power supply circuit and an interlock switch (11) for electrically disconnecting the power supply circuit. The switching apparatus also includes a lever (7) which is rotatably supported by one of the base and the housing and also is engaged with an engaging section (49, 51) formed in the other of the base and the housing. The lever causes a wall of the housing to be slid in a depth direction of an annular groove (19) of the base in accordance with a rotation of the lever. The interlock switch is disconnected ahead of the main switch by separating a movable terminal (31a, 31b) of the interlock switch away from a fixed terminal (27) of the interlock switch when the lever is rotated to cause the housing slid in a direction away from the base.
摘要:
Es wird ein elektrisches/elektronisches Installationsgerät vorgeschlagen, welches ein Gehäuse aufweist dessen Sockelteil zur Aufnahme zumindest einer Funktionseinheit und dessen Deckelteil zumindest zur Anordnung und Aufnahme mehrerer Betätigungstasten vorgesehen ist. Zu dem Zweck ein elektrisches/elektronisches Installationsgerät zu schaffen, dessen Lichtleiteranordnung bei Realisierung einer besonders guten Beleuchtungsqualität einen besonders einfachen Aufbau aufweist und welche sich zudem auf besonders einfache Art und Weise herstellen und montieren lässt, besteht die Lichtleiteranordnung aus zumindest einem ersten Lichtleitelement, welches mit seinem Lichteinkoppelbereich zumindest einem auf einer Leiterplatte angeordneten Leuchtmittel zugeordnet ist, und welches durch die Formgebung und Anordnung seiner Reflektionsbereiche und seines Lichtauskoppelbereiches das eingespeiste Licht durch Reflektion gezielt in zumindest ein zweites Lichtleitelement einspeist, welches zum Zwecke der Beleuchtung zumindest einen Lichtaustrittsbereich aufweist.
