Abstract: A knob is attached to a distal end of a lever and has an approximately cylindrical knob body, a cap attached to a distal end of the knob body, and a metal-plated operating member attached to a side face of the knob body. The knob body has a pair of guiding protrusions that define a slit extending in an axial direction of the lever. The operating member includes a rib formed integrally therewith and a flange coupled to the rib approximately perpendicularly thereto. The flange is wider in width than the slit and engages the guiding protrusions due to insertion of the rib into the slit according to insertion of the operating member into the knob body in the axial direction.

Abstract: A contact structure of a combination switch, includes a contact board, a fixed contact piece, a fixed contact and a plurality of moving contacts. The fixed contact piece for being supplied with a large current is provided on the contact board. The fixed contact for being supplied with a small current, is provided as part of a wiring formed on the contact board. The plurality of moving contacts slide over the contact board such that the fixed contact piece and the fixed contact are respectively brought into contact with the moving contacts.

Abstract: A connector structure of a motor vehicle door is provided, by which a space for mounting electric components can be secured in a vehicle body and the cost of the electric component can be reduced by making the connector have multifunction. The connector structure includes a first female terminal forming a break contact provided in one connector selected between a first connector at a vehicle body-side and a second connector at a door-side; and an insulating member provided in the other connector, so that the insulating member is inserted into the first female terminal when the first and second connectors engage with each other, thereby an electric circuit can be cut. A second female terminal forming a make contact is provided next to the first female terminal and a male terminal forming a break terminal coming in contact with the second female terminal is provided next to the insulating member.

Abstract: A combination switch is provided with a movable knob and a contact assembly. The movable knob is rotatable with respect to a lever base and has a movable contact. The contact assembly includes a holder, a volume plate and a rivet. The holder has a bottom portion opposite to the movable contact, a cylinder portion projecting from the bottom portion and fixed to the lever base, and a terminal plate fixed within the bottom portion. The volume plate is disposed on the bottom portion of the holder, and has a fixed contact slidably in contact with the movable contact. The rivet fixes the volume plate on the bottom portion, and electrically connects the fixed contact with the terminal plate. As mentioned above, a reliability and an assembling characteristic are improved by assembling between the volume plate and the holder, and between the volume plate and the rivet.

Abstract: A circuit board connector for improving the reliability in the electrical connection of a joint section between a circuit board and a terminal, includes a housing and a pair of flexible arms extending downwards in the housing and adapted to lock a connection terminal with the housing, a slit-like gap being provided between the two flexible arms, semi-ellipsoidal engagement protrusions being provided on the arms at positions where they are opposed to each other. The connection terminal has a substantially rhombic engagement hole which is to be engaged with the engagement protrusions. When the flexible arms in the housing undergo thermal expansion as a result of a rise in temperature, the engagement protrusions move downwards while remaining in abutment with oblique inner edges of the engagement hole, thereby absorbing dimensional changes of the housing.
