  • Patent number: 5053907
    Abstract: A hybrid relay comprising a mechanical relay provided with mechanical contact unit adapted to be actuated by an electromagnet, an electronic relay consisting of a semiconductor device, and a drive switch for supplying a drive current to the electromagnet, wherein the mechanical contact unit comprises: a first contact mechanism for controlling a load current of the hybrid relay; and a second contact mechanism for controlling a control current for a control gate of the semiconductor device; a contact point gap of the first contact mechanism being larger than that of the second contact mechanism. Thus, it is ensured that the first contact mechanism is engaged after the second contact mechanism and is disengaged before the second contact mechanism. Preferably, the mechanical contact unit further comprises a third contact mechanism, for controlling the leak current of the semiconductor device, which may be provided with a delay mechanism for delaying the returning action thereof.

  • Patent number: 4561045
    Abstract: An illuminated display assembly comprising a light emitting member, a socket base member, a cap member housing the light emitting member therewithin and including at least one engaging leg to be engaged with the socket base member, and connection means carried by the socket base member for disengageably contacting a connection terminal of the light emitting member, the light emitting member being removably supported within the case member.

  • Patent number: 4551592
    Abstract: An improved push-button switch which is so arranged that generation of heat at a journalled portion of a movable piece is eliminated by forming contacts of the movable piece into double-break contacts so that no current flows through the journalled portion, while a sufficient contact gap is available even when the push-button switch is made into a compact size.
