As this type of switch, for example, a changeover switch called a three-way switch as shown in FIG. 6 is conventionally known. The illustrated switch is formed by connecting a body 10 having an open surface on one side and a cover 20 holding a swinging reversing handle 50 to form a body 1, and the body 10 is provided with a terminal device. The three terminal boards 32, 45, and 46 constituting the terminal are housed. Fixed contacts 41b (one fixed contact is present at a position not visible in the figure) are held by the terminal plates 45 and 46, respectively, and the fixed contacts 41b face each other. An open / close element 40 'is swingably supported on the remaining terminal plate 32, and two open / close elements 40' are inserted between the fixed contacts 41b and can be separated from and connected to the fixed contacts 41b. The movable contact 42a (one movable contact exists at a position that cannot be seen in the figure) is held. The opening / closing element 40 'holds a reversing spring 44 between itself and the reversing handle 50. When the reversing handle 50 swings, the opening / closing element 40' swings, and each movable contact 42a becomes a corresponding fixed contact 41b. Is configured to selectively contact the That is, the state in which the electric path between the terminal plate 32 and the terminal plate 45 is closed with the swing of the reversing handle 50 and the state in which the terminal plate 32

When the electric wire is formed in the body 1 through the electric wire insertion hole 12 when the electric wire is inserted into the body 1 between the main piece 32a, 45a, 46a, the contact piece 33a and the lock piece 33a. The terminal device 30 is sandwiched between the terminal device 30 and the main piece 32a, 45a, 46a.
The wires b, 30c, and 30d are electrically connected to the wires, and are mechanically held so that the leading edges of the locking pieces 33b bite into the wires so that the wires do not fall out of the body 1. In particular, the locking pieces 33b are attached to the main pieces 31b, 45b, 46b in the direction of inserting the electric wire through the electric wire insertion hole 12.
And the locking piece 33b is unlikely to bend against the force of pulling out the wire,
The wire is surely prevented from being pulled out. here,
The electric wire is an insulated wire, and the portion of the wire to be inserted into the housing 1 is stripped of the insulating coating so that the core wire is exposed. Therefore, the fact that the electric wire is clamped between the main pieces 32a, 45a, 46a and the locking spring 33 means that the core wire is actually clamped.

Now, it is assumed that when the right end of the operation handle 60 is located rearward (downward in the figure) of the left end as shown in FIG. 1, the movable contact 42a comes into contact with the fixed contact 41a. At this time, the reversing spring 44 is in a state where the intermediate portion is expanded to the left side from the both ends, and the movable contact 42a is pressed against the fixed contact 41a by the reversing spring 44 to apply a contact pressure. On the other hand, when the left end of the operation handle 60 is pushed backward from this state, the front end of the reversing spring 44 moves to the right, so that the reversing spring 44 is rapidly expanded after being compressed, so that the middle portion is larger than the both ends.

Therefore, when an electric wire whose core wire is a stranded wire is introduced from the electric wire insertion hole 12, even if the electric wire tries to spread apart, the wire gets over the guide protrusion 38 and the lock piece 33 b and the guide protrusion 38 The electric wire is securely held therebetween, and the electric wire is guided so as to pass between the two guide projections 38 as much as possible. In short, even if the electric wire is a stranded wire, it is possible to reduce the possibility that the electric wire spreads apart. Furthermore, the position of the guide projection 38 is the lock piece 33.
b, the electric wire is connected to the guide projection 3
Even when the vehicle rides on 8, the relatively large contact pressure can be applied to the electric wire from the lock piece 33b, and the electric connection of the electric wire can be reliably ensured.
