An illumination type keytop is disclosed, in which a transmitted light restricting member is disposed opposite to a display portion formed in a part of a light intercepting layer and a colored and transparent filter member is disposed on the rear side thereof so that the display portion can be illuminated with light having a high directivity, which has passed through the transmitted light restricting member, at the illumination in the night, etc.

Illumination type keytop

A connection device for spaced electric components comprises a guide member made of a flat resilient tubular member having a plurality of windows and bridge portions alternating on the major surfaces of the tubular member, or alternatively, a guide member made up of a plurality of guide elements having bridge portions on opposite surfaces between the longitudinal edge portions. A slide member made of a resilient material is introduced through the guide member. Projections are formed on the inner surfaces of said bridge portions of the guide member and escape portions are formed between end portions of said projections to allow the slide member to be moved easily within the guide member.

Connection device for spaced electric components

A remote operation device for operating a plurality of remotely positioned electric parts simultaneously by an actuation of a single operation member. The device has the operation member, interconnection members each having a flexible sleeve and a metallic belt slidably received by the sleeve, and operated members connected to the operating portions of the electric parts. The metallic belts of the interconnection members are superposed at their one ends to one another and are secured commonly to a movable connection member slidably mounted in the operating member, while the other ends of the metallic belts are connected to movable connection members slidably received by respective operated members. As the signal movable connection member of the operation member is moved in one direction, the movement is transmitted through respective metallic belts to respective operated members, so that the electric parts are operated simultaneously.

Remote operation device

A remote operation device for interconnecting moving portions of spaced electric components by means of a resilient interconnection member which enables remote operation of one the electric components by actuation of the other. The device includes blocks connected removably to respective ends of the interconnection member and each adapted to be connected removably to respective ones of the spaced electric components.

A miniature change-over switch is disclosed which comprises a grounding spring member attached to a metal frame and having two arms engaging a camming projection formed on a slider. The camming projection is adapted to move one of the arms by a camming action so as to disconnect it from one of the stationary terminals while at the same time the projection is released from the other of the arms so as to connect the arm to the other of the stationary terminals when the slider is moved to cause a movable contact element to connect a common terminal to the one stationary terminal and to disconnect it from the other stationary terminal.
