And a movable contact 3 comprising a lever member 5 actuated so as to be in contact with and separated from the movable contact 3 and pivotally support the movable contact 3 so as to be vertically movable along the vertical axis between the fixed contacts 2a and 2b. It mainly comprises a solenoid mechanism 4 provided.

The casing 1 is made of a pair of substantially parallel and spaced apart upper side plates 6 and 6 made of a suitable electric insulating plate material such as polycarbonate, and is integrally formed with the upper side plates 6 and 6 respectively. Lower side plates 7, 7 which are fixed and connected to each other and have bent portions 8 at their lower ends, and are made of a metal material such as iron or steel and plated with nickel. The fixed contacts 2a and 2b are attached to the portions at a horizontal interval in the figure. In the upper center of the upper side plates 6, 6 of the casing 1, there are provided notches 9, 9, which are elongated in a downward direction, and are formed so that the creepage distance between the fixed contacts 2a, 2b can be increased. ing.

In the figure, the fixed contacts 2a, 2b provided at intervals in the horizontal direction are composed of cylindrical members whose upper surfaces are notched flat, and terminals 10 and 10 for cable attachment are provided on these flat portions. Each is provided. The fixed contacts 2a and 2b are made of a metal material having good conductivity such as brass or copper, and the surface thereof is suitably plated with, for example, nickel, and is fixed by an appropriate fixing member 11 such as a flathead screw. It is fixed to the upper side plate 6 of the casing 1.

The movable contact 3 that comes into contact with the fixed contacts 2a and 2b is composed of a lever member 5 formed by shaping both ends of a cylinder into a spherical shape and forming a semi-cylindrical surface. The solenoid mechanism 4 has a normal configuration including a fixed portion 12 such as a coil and a movable portion 13 such as a core, and is configured such that the movable contact 3 is moved up and down by the solenoid mechanism 4. ing. That is, the lever member 5 constituting the movable contact 3 is pivotally supported by a pin 14 near one end by a pin 14 to a supporting wall member 15 connected to the movable portion 13 of the solenoid mechanism 4, and the fixed contact 2a, 2b The lever member 5 is formed so as to operate from a first operation state (FIG. 5), which will be described later, to a second operation state (FIG. 6) or vice versa. The solenoid mechanism 4 has a normal configuration including a fixed part 12 and a movable part 13. A plunger 16 is provided at the bottom of the movable part 13 that moves up and down with respect to the fixed part 12. At the both ends of the connecting shaft 17, there are provided elongated support members 18 made of an electrically insulating plate material such as polycarbonate. It is fixed by screws 19 made of an insulating material. The plunger 16 is preferably made of an appropriate metal material such as iron or steel, and is preferably subjected to nickel plating, and the connecting shaft 17 is preferably made of a metal material such as brass. Further, the movable portion 13 of the solenoid mechanism 4 is configured such that when it is separated, the movable contact 3 is lowered by gravity, and the movable contact 3 is separated from the fixed contacts 2a, 2b.

In the thus constructed switch device of the present invention, as shown in FIG. 4, the lever member 5 of the movable contact 3 is separated from the fixed contacts 2a and 2b when no power is supplied. For example, the distance S1 between one fixed contact 2a and the movable contact 3 is about 5.5 mm, and the distance S2 between the other fixed contact 2b and the movable contact 3 is about 15 mm. Therefore, the distance between the three-point contacts (S1 + S2) is considerably large at about 20.5 mm, and a separation distance about twice as large as that of a normal contact can be obtained.

As described above, when the solenoid mechanism 4 is operated by being energized from the non-energized state, the movable part 13 of the solenoid mechanism 4 is raised, and the lever member 5 of the movable contact 3 is pivoted. As shown in FIG. 5, when one end of the lever member 5 of the movable contact 3 comes into contact with one of the fixed contacts 2a, the first operating state is reached, and when the movable portion 13 of the solenoid mechanism 4 is further raised, As shown in FIG. 6, the lever member 5 of the movable contact 3 moves like a lever, and the lever member 5 is completely brought into contact with the other fixed contact 2b to be closed. At this time, the suction distance of the solenoid mechanism 4 is almost the same as the normal one.

In order to open the circuit, when the energization of the solenoid mechanism 4 is released, the movable contact 3 is lowered by the gravity of the movable portion 13 of the solenoid mechanism 4, and moves from the fixed contacts 2 a and 2 b to the movable contact. The fixed contacts 2a and 2b and the movable contact 3 are separated from each other at a substantially same solenoid working distance and approximately twice as large as a normal distance.
