Abstract: A coil device includes a coil portion and a bobbin. The coil portion includes wires connectable to terminals. The bobbin includes a first terminal block and a second terminal block formed on both sides in a winding axis direction of a cylindrical portion for forming the coil portion around the cylindrical portion. A length of the first terminal block in a width direction perpendicular to the winding axis direction is larger than that of the second terminal block in the width direction.

Abstract: A two-directional switch for a motor cycle and the like having a control knob for a contact holder adapted to slide in a first direction and a second direction intersecting the first direction approximately at right angles therewith, and having the parts so arranged that the sliding movement in the first direction is guided by a guide plate, and the sliding movement in the second direction is guided by a guide member for guiding the guide plate, while engaging members are provided respectively between the guide plate and the contact holder or control knob and between the guide plate and guide member so as to prevent the control knob from unduly moving from a predetermined position in either of the first and second directions for maintaining the expected switch functioning.

Abstract: A signal switching system for actuating winking lights to be used for motor vehicles, for example, two-wheeled vehicles comprises an operational lever resiliently maintained in a substantially upward direction; one movable electrical contact portion for sending out an operational signal for actuating the winking signals, which is to be movable toward right and left with respect to a neutral state thereof for selectively contacting one of fixed contacts in accordance with a corresponding movement of the operational lever with respect to a neutral position while being arranged to be resiliently back to the neutral state thereof; and a cancelling signal switch means to send out a signal for winking signals to be put off when the operational lever is pushed substantially downward at the neutral position thereof.
