To enable reduction of the number of components and weight, improvement of workability, and reduction of the costs, a switch contact structure is disclosed, which comprises a substrate, a movable blockdisposed so as to be movable along the substrate, a fixed contactmounted on the substrate, and a movable contact mounted on the movable block, wherein the movable contact is brought into and out of contact with the fixed contactby the movement of the movable blockalong the substrate, characterized in that the fixed contactis formed of conductive wire material, and in that both endsof the fixed contactare fixed on the substrate

Switch contact structure

A switch device is provided, which has a function of preventing reverse flow of current and reducing the number of switch terminals or harnesses. The switch device has a plurality of fixed contacts and a plurality of movable contacts to contact the fixed contacts. The movable contacts have an electronic element provided between contact members.

Switch structure with electrical device

A combination switch for a vehicle which employs only one connector for electrical connections. A body is formed with a first recess and second recess formed on the left and right sides of the body, respectively. A first switch is mounted to the first recess, and a second switch is mounted to the second recess. A terminal block is mounted to the body between the first and second switches. The terminal block electrically connects the first switch and the second switch. An electrical connector is provided on either the first switch or the second switch for connecting to an external connector.

Construction of combination switch for vehicle

A lever switch for a vehicle including a boot having a good appearance. A manipulation lever 1 passes through a lever insertion hole 10a formed in a column cover 10 and is mounted pivotably in a switch case 5 by insertion. The boot 9 blocks a space between the switch case 5 and the lever insertion hole 10a, and a filling-up member 20 is engaged with a cut-off portion 9d of an opening portion 9c thereof, which is opened approximately in a trumpet shape. Engaging grooves 9f, with which guide rails 20a of the filling-up member 20 are engaged, are formed in inner surface portions opposite to each other of the cut-off portion 9d in the boot 9. Engaging grooves 2f are formed in the boot 9 in the inner surface portions opposite to each other of the cut-off portion, with which nails 20c or elastic nails 20d are engaged. In the filling-up member 20 there is formed a holding groove 20b, which holds a cord 21 wired on the manipulation lever 1 and hung therefrom together with a side wall 5h of the switch case 5 by putting the cord 21 between the holding groove 20b and the side wall 5h.

Lever switch for a vehicle

A lever switch apparatus has a lever operable in a plurality of directions, which, when operating the lever in a certain direction, prevents against erroneous operation of a movable board by rendering the movable board immovable in an irrelevant direction of lever operation. The lever switch apparatus has a lever 2 and a movable board 3A. The lever 2 is swingable in a first direction and a second direction about a first axis 21 and a second axis 22, and has an engager 23 on a tip side thereof. The movable board 3A is swingable in a third direction about a third axis 31A, and has an elongate hole 32A extending in the second direction and a contact piece 33A. The engager 23 is engaged with a wall surface 34A of the elongate hole 32A. The elongate hole 32A is formed in a curved form corresponding to a swing path of the engager 23 to prevent erroneous operation of the movable board 3A during movement of the lever 2 in certain directions.

Lever switch apparatus

A slide switch 1 includes a movable contact 2 that has projections 11 formed thereon for preventing dislocation. The movable contact 2 is inserted together with a spring 8 into a holder 3. The holder 3 has regulating recesses 12, within which the projections 11 of the movable contact 2 can move only vertically. The holder 3 also has claws 9. The movable contact 2 has holes 10 that engage with the claws 9. A pole plate 4 has fixed contacts 5 fixed thereon, on which the movable contact 2 can slide with the holder 3 in compressive contact with the fixed contacts to switch the contact positions. At least one of the fixed contacts 5 is formed with a chamfer 15. Resin guide members 18 are fitted in the centers of slits 17 in the pole plate 4 for preventing the movable contact from falling into the slits. This structure prevents the movable contact of the slide switch from being dislocated when the contact positions of the slide switch are switched, and increases the durability of the slide switch.
