[0002]

2. Description of the Related Art In recent years, the number of electric devices mounted on vehicles has been steadily increasing, and an increase in wire harnesses has become a problem. For example, in the case of doors, there are electric devices such as power windows, electromagnetic door locks, electric mirrors, etc., and dozens of harnesses penetrate the door panel, making it difficult to secure wiring openings and secure door panel strength. It is becoming.
Of these, the power window, etc., must be operable by the remote control from the driver's seat and also by the hand switch provided on the door near the front passenger seat or the rear seat, and the signal line to the electromagnetic relay that drives the door window opening / closing motor Increases,
The above problem is exacerbated. Therefore, there has been proposed a relay device which incorporates switch contacts of a manual switch, eliminates external wiring from the hand switch to the electromagnetic relay, and aims at solving the above-mentioned problems. An example is shown in FIG.

In FIG. 1, a board 5 'is disposed in a horizontal position in a casing 1, and a relay drive circuit is formed on the board 5' by printed wiring. Terminals of a pair of electromagnetic relays 4A (only one is shown) housed in the same casing 1 and a connector housing 10
Each of the connector terminals 101 extends in the direction of the board 5 ', is inserted into a through hole which is connected to a printed wiring on the board 5', and is connected and fixed by soldering. Circuit elements such as a resistor and a diode constituting the relay drive circuit are also soldered and connected in predetermined through holes. The operation switch includes fixed contacts 102 on the substrate 5 'and movable contacts 103 opposed thereto.
The movable contact 103 is joined to a space top surface of a rubber elastic body 104 provided so as to cover the fixed contact 102. The rubber elastic body 104 has a portion where each movable contact 103 is joined protrudes upward, and the protruding end thereof has a bar-shaped slider 10 slidable up and down.
5 is in contact from above. An operation lever 2 is provided on the casing 1 so as to be exposed. The operation lever 2 is formed in a container shape which is opened downward, and the handle 22 is gripped by a support shaft 25 provided in the center of the lower side thereof to perform a swing operation. (Arrows in the figure) Yes. The operation piece 26 protruding downward from the center of the top wall of the operation lever 2 has two protruding portions 261 at the tip and abuts on the upper end of the slider 105.

With this structure, when the operation lever 2 is operated to swing forward and backward, the left and right sliders 105 are selectively pushed down, and the projection of the rubber elastic body 104 is deformed downward and fixed. The contact 102 and the movable contact 103 are brought into contact conduction. Then, these contacts 102 and 103
The electromagnetic relay 4A is actuated by conduction between the terminals or an external signal input from the connector terminal 101.
