Description

[Detailed Description of the Invention] The present invention relates to a toggle switch, in which a plate having a generally V-shaped cross section and both left and right end portions thereof are bent outward to form an end portion for connecting an electrode terminal, and the plate having a generally V-shaped cross section is bent outwardly to form an end portion for connecting an electrode terminal. A drive plate in which the protrusions provided at both the left and right front and rear ends are bent outward to form electrode terminal connection ends, with the central bending part as a border, and the electrode terminal connection ends of the drive plate. The drive plate is disposed between the upper part of the electrode terminal and the lower part of the operating member, and the operating member is configured to operate the operating member. By configuring the electrode terminal connection end of the drive plate to come into contact with two different electrode terminals when operated, the toggle switch can be made smaller, has fewer parts, is easier to manufacture, and is easier to manufacture. An object of the present invention is to provide a low-cost toggle switch that is excellent in stabilizing a drive plate during switching.

Conventionally, for example, as a three-pole toggle switch for ON, ON, OFF, three flat fixed contact pieces are fixed side by side facing each other through the bottom wall of an insulating box, and two of the two adjacent sides are fixed in parallel. As a result, a high upright insulating column is formed integrally with the insulating box, and the movable contact piece bent in a dogleg shape and its central bent part are placed on top of it so that it is located between the two contact pieces. However, a changeover switch has been proposed (Japanese Utility Model Publication No. 36-29932) in which a slider is mounted on a movable contact piece and is pressed by a spring to slide from side to side.

However, the movable contact piece (drive plate) in this proposed changeover switch (toggle switch) has a disadvantage that the stability of the movable contact piece is not very good when switching the switch.

The present invention eliminates the above-mentioned drawbacks, and examples thereof will be described below.

Fig. 1 is a sectional view of one embodiment of a toggle switch according to the present invention, Fig. 2 is a sectional view taken along line A-A in Fig. 1, and Fig. 3 is a perspective view of a drive plate used in the toggle switch. , 4 and 5 are explanatory views of the operation of the drive plate of this toggle switch.

In the figure, 10 is a cylindrical contact lever, and this operating lever 10 is attached to a housing 11 so as to be movable in the direction of the arrow around a fulcrum 10'. A coiled spring 12 is arranged inside the cylindrical shape of the operating lever 10, and the other end of a shaft 14 having a substantially triangular stud 13 attached to one end is inserted. It is designed to constantly receive repulsive force from the spring. 15, 16, 17 and 18 are 1 on the bottom of the housing.
These are electrode terminals arranged in rows, 19 and 20.
is a convex portion formed on the housing between the electrode terminals 15 and 16 and the electrode terminals 17 and 19. Reference numeral 21 denotes a drive plate having a substantially M-shaped cross section for electrically connecting electrode terminals, and this drive plate 21 has electrode terminals 16 and 17 on both sides of a center portion 22 of the substantially rectangular plate, respectively. In addition, the metal plate with the protrusions 23 and 24, which are formed in a positional relationship in contact with the inner sides of the protrusions 19 and 20 of the casing, is moved approximately 90 degrees outward with the protrusions 23 and 24.
It is made by bending the metal plate at an obtuse angle inward at the central portion 22, and then bending the metal plate outward at an obtuse angle near both end portions 25 of the metal plate. Such a driving plate 21 is disposed above the electrode terminal portion and below the stud, and by moving the operating lever, for example, as shown in FIG. 4, the electrode terminals 15 and 16 are connected. Then, by moving the operating lever as shown in FIG. 5, the electrode terminals 17 and 18 are connected. and,
If all electrode terminals are connected externally,
It is now possible to switch the switch in three consecutive stages, such as ON→ON→ON, and if the rightmost or leftmost electrode terminal is not connected to the outside, the switch can be switched ON→ON→ON. A switch such as OFF or OFF→ON→ON can be performed.

In addition to the drive plate shown in FIG. 3, the drive plate described above may be one in which the tip of the drive plate shown in FIG. 3 is bent slightly inward, as shown in FIG. 6, for example.

The toggle switch of the present invention, which corresponds to the conventional two-pole three-stage toggle switch, has four electrode terminals 40 and 41 arranged in two rows, as shown in a partially cross-sectional view in FIG. A drive plate 42, 43 similar to that described above is arranged for each row, a stud 44 is arranged for these drive plates, and a shaft 4 is connected to the stud 44 to an operating lever.
5 to move the drive plate and connect the electrode terminals.

The toggle switch of the above embodiment, that is, the toggle switch shown in FIG. The toggle switch shown in FIG. 7 only requires two rows of electrode terminals, and the toggle switch can be made smaller accordingly.
Further, unlike conventional toggle switches, there is no need to connect electrode terminals in different rows with external lead wires, making the toggle switch that much easier to manufacture. or,
The number of drive plates is also reduced, which not only reduces the number of parts, but also reduces material costs.
It requires less assembly time and can be done at a lower cost. Furthermore, when the drive plate is moved by the operating lever, the stability of its operation is significantly better than when the drive plate simply has a V-shaped cross section.

As mentioned above, the toggle switch according to the present invention is
The approximately V-shaped cross-section plate and both left and right end portions are bent outward to form ends for connecting electrode terminals, and the left and right front and rear ends of the approximately V-shaped cross-sectional plate are bent at the center bending portion of the plate. A drive plate having a convex portion bent outward to form an electrode terminal connection end, an electrode terminal provided corresponding to the electrode terminal connection end of the drive plate, and the drive plate. the drive plate is arranged between an upper part of the electrode terminal and a lower part of the operation member, and the end of the drive plate for connecting the electrode terminal changes depending on the operation of the operation member. Since the drive plate is configured to come into contact with the two electrode terminals, that is, the drive plate that is operated by the operation of the operating member is provided with an end for connecting the electrode terminals.
When switching the switch, the amount of movement displacement of the drive plate is small, and since the amount of movement displacement of the drive plate is small, the movement of the drive plate can be performed stably and smoothly, and therefore the switch can be changed stably and smoothly. In addition, since the drive plate is provided with an end, there is no need to provide a special support member for the drive plate, and there is only a wall for regulating the position of the drive plate in the front and back direction of the drive plate. Since the drive plate operates stably and therefore does not require any extra parts, the structure of the toggle switch can be simplified accordingly, and it has the advantage of being small and low cost.
