When the cylindrical member is rotated in accordance with the rotation of the rotating member, the second magnet is connected to the energizing terminal of the lamp board to which the battery power is connected. It is proposed a waterproof switch structure to be made. However, this structure has a problem in that the structure is very complicated, so productivity and assembly are bad, and the battery is not easily replaced since the cable is welded to the positive electrode of the battery.

On the other hand, Utility Model Registration No. 361721 proposes an underwater light using a high-pressure discharge lamp. The underwater light is rotatably provided with a rotary switch incorporating a small magnet on the outside of the light main body, and inside the rotary light switch. Disclosed is a waterproof switch structure having a plurality of Hall sensors for magnetically detecting a rotational position and selecting a main light source, an auxiliary light source, and an off position according to the position of a rotary switch.

The O-rings 1, 2, and 3 make the inside of the case completely waterproof when the body 11 and the upper cap 12 and the lower cap 13 are screwed together and compressed.

Hereinafter, a waterproof switch structure according to the present invention will be described.

In the waterproof switch of the present invention, the lower cap 13 has a cylindrical portion 13f having a front end portion 13d screwed to the rear end portion 11b of the body 11 and a circular diaphragm at an intermediate portion of the cylindrical portion 13f. 13a is integrally formed, and a pair of first and second protrusions 13b and 13c extending inward and outward from the central portion of the diaphragm 13a, respectively, serve as a hinge axis, and the cylindrical portion 13f is formed. The rear end 13e of) is extended longer than the second projection 13c so as to protect the drive knob (to be described later) installed in the second projection 13c.

It is also possible to have a structure in which a metal piece made of metal, a cable connected to the metal piece at both ends, and the like are built up to this position. However, in terms of waterproof performance, a case made of a nonmagnetic metal such as Al exhibits excellent waterproofing performance compared to a case made of a plastic material.

Since the suction knob 31 continues to act as a suction force between the first and second magnets, the free end of the movable power supply terminal 35 has a lower cap while the movable knob 32 is kept in the ON position. The state of contact with the wall surface of (13) is maintained. In this case, preferably, when the leading end of the movable knob 32 is positioned in the OFF position and the ON position, the inner circumferential portion of the lower cap 13 protrudes by a predetermined thickness so that the position is fixed by snap engagement. It is recommended to design as possible.

Thereafter, when the power supply of the lantern is to be stopped, the tip of the movable knob 32 is turned to the OFF position, and the driven knob 31 also faces the OFF position along the movable knob 32. The free end of the movable power supply terminal 35 is separated from the wall surface of the lower cap 13 by the restoring force, and the power supply of the battery 14a-14c is cut off, so that the LED 21 is turned off. .

Therefore, in the present invention, the power supply control for the LED 21 from the battery BAT can be made in a state of maintaining a completely waterproof, the entire lantern by implementing a part that is most vulnerable to waterproof in the lantern to be completely waterproof Waterproof can be achieved.

In the above-described embodiment, a case of using a cylindrical battery as a power source is illustrated, but it is applicable to a power supply control switch when a rectangular battery is used in addition to the cylindrical battery. In addition, although the use of a high-brightness LED as the light emitting means is illustrated, it is also possible to use a variety of well-known tubular lamp.

The coupling hole 320a which is integrally formed by insert molding and coupled to the second protrusion 13c is formed at the other end, and the second magnet 321 is more predetermined than the knob body 322 as shown in FIG. 3C. It protrudes by a height to serve as a handle during the pivoting movement of the drive knob (320).

Since the driven knob 310 and the movable knob 320 of the first modified example are provided with the first and second magnets 311 and 321, respectively, they are turned on in the same manner as the embodiment shown in FIGS. 1 and 2. When the movable knob 320 is turned to the position and the OFF position, the driven knob 310 is rotated accordingly, so that the power supply of the batteries 14a to 14c can be controlled.
