Description

DETAILED DESCRIPTION OF THE INVENTION (A>Field of Industrial Application)
This invention relates to an improvement of a sliding type power switch, which is used to turn off the power, and is turned on and off by sliding the knob.

(B) Prior Art A conventional power switch, which is turned on and off by sliding a knob, is as shown in the sectional view of FIG.

That is, the spring insertion hole 3 is inserted into the slide portion 2 of the knob 6 located inside the body 1 of the power switch.
, insert the spring 4 into the insertion hole 3, fix the ball 5 to the lower end of the spring 4 with grease, slide the ball 5 by sliding the knob 6, and the ball 5 will come into contact with it. The movable piece 7 is moved to switch the contact 8.

This type of sliding power switch also succeeded in reducing the overall height compared to previous power switches that used push rods.

However, this type of sliding power switch has problems such as the need to change the shape of the knob when using a bipolar switch, even if it is a single-pole switch. It ended up being a power switch with a lot of noise.

(C) Problems to be solved by the present invention Therefore, the present invention uses a leaf spring 10 on the lower surface of the slide portion 2 of a sliding type power switch instead of the conventional ball or push rod. To provide a slide type power switch which can suppress the overall height without changing the shape of the knob 6 even if there is a switch 6, and which is easy to assemble.

(D) Means for Solving the Problems In order to solve the above-mentioned problems, the present invention provides a mechanism that corresponds to the number of switching movable pieces 7 on the lower surface of the slide portion 2 which is connected to the knob 6 and slides inside the body 1. A sliding type characterized in that a fitting groove 9 is bored, and a plate spring 10 bent downward in a convex manner so as to partially abut the movable piece 7 is fitted into the fitting groove 9. It is intended to provide a power switch.

(E) Examples The following will explain the embodiments shown in the drawings.

FIG. 1 is a sectional view showing the ON state of a power switch according to the present invention, and FIG. 2 is a sectional view showing the same OFF state.

In the figure, 1 is a body, and the body 1 is provided with a contact 8 connected to a terminal 12 and a movable piece 7 connected to a terminal 13. When the movable piece 7 and the contact 8 come into contact with each other, the switch is turned on, and when they separate, the switch is turned off.

In this respect, there is no difference from a conventional sliding power switch.

The upper part of the body 1 has a slide part 2 which is connected to a knob 6 and which slides inside the body 1, which is a feature of the present invention. Fitting grooves 9 corresponding to the number of switching movable pieces 7 are bored in the lower surface of the slide portion 2 .

In the illustrated embodiment, the fitting groove 9 is a long groove cut in the same direction as the movable piece 7.

As shown in FIGS. 1 and 2, a plate spring 10 is fitted into the fitting groove 9, with a portion of the plate spring 10 bent downward in a convex manner so as to come into contact with the movable piece 7.

Note that 11 in Figure 2 is a cover, and by covering with the cover 11, there is no difference in appearance from a conventional sliding type power switch.

(F) Effects of the present invention Since the present invention is constructed as described above, it exhibits the following effects.

Firstly, unlike the case of using a push rod or the ball 5 shown in FIG. 3, the present invention does not require a vertical space for attaching a member that restricts the movement of the movable piece 7.

Since the leaf spring 10, which performs the same function as a push rod or the like, is held in the horizontal space, if there is a space smaller than the slide part 2, it is possible to manufacture a switch of a desired pole with a low height. can.

Second, since the leaf spring 10 that presses the movable piece 7 is held by its own pressing force against the fitting groove 9, it is only necessary to fit it into the fitting groove 9, and the conventional slide type power supply using the ball 5 is sufficient. It is extremely easy to assemble compared to a switch.

[Brief explanation of the drawing]

FIG. 1 is a sectional view showing the ON state of the power switch according to the present invention, FIG. 2 is a sectional view showing the same OFF state, and FIG. 3 is a sectional view showing a conventional power switch.

Claims (1)

[Claims] Fitting grooves 9 corresponding to the number of switching movable pieces 7 are bored in the lower surface of the slide part 2 that is connected to the knob 6 and slides inside the body 1, and a part of the movable pieces 7 are inserted into the fitting grooves 9. A slide type power switch characterized in that a plate spring 10 is fitted with a plate spring 10 bent downward in a convex shape so as to come into contact with each other.
