  • Patent number: 5457443
    Abstract: A combination switch for performing various functions comprises a fixed substrate having an output contact assembly which has a common output contact and other output contacts which are electrically insulated from the common output contact. The switch also comprises a movable substrate having a switch contact assembly which has a common contact and other contacts which are electrically connected to the common contact. A switch lever is for moving the movable substrate with respect to the fixed substrate to shift the switch contact assembly relative to the output contact assembly, thereby selectively connecting the common output contact to the output contacts through the switch contact assembly to supply from the output contact assembly a pattern signal indicative of one of different conductive patterns. A processor judges, in response to the pattern signal, to which function the conductive pattern corresponds and producing an operational signal for performing the indicated function.

  • Patent number: 5350893
    Abstract: In a lever switch, a contact actuating part provided in a lever is movable in a first direction by shifting of the lever and the top portion of a movable contact is depressable in a second direction substantially at right angles to the first direction while being pressed by a pressing force caused by the movement of the contact actuating part. The lever switch includes a plate which is provided between the contact actuating part and the top portion of the movable contact to convey the pressing force to the movable contact. The top portion has a sloped face facing the contact actuating part so as to form an angle of friction .theta. 1 with respect to the first direction, the plate has a central part and a side part which is bent toward the contact actuating part so as to form an angle of friction .theta. 2 with respect to the first direction, and the angle of friction .theta. 2 is smaller than the angle of friction .theta. 1.
