Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a switch device used in various electrical devices.

[Prior Art] Conventionally, switch devices for electrical equipment such as ventilation fans and air conditioners have widely used operating members with drawstrings or knobs, as shown in, for example, Japanese Utility Model Application No. 59-32228. It has been adopted. As shown in FIGS. 3 and 4, this type of switch device has the same main body 12, although the operating member is a pull string 10 or a knob 11. That is, if the drawstring 10 is connected to the operation member attachment portion of the main body 12, it will become a drawstring type, and if the knob 11 is connected, it will be a knob type.

[Problems to be solved by the invention] The above-mentioned conventional switch device can be either a pull string type or a knob type, but once either type has been determined and it is attached to an electrical device, changing the operating member is troublesome. Therefore, it has not been possible for users of the electrical equipment to easily change the operating members as necessary.

This idea was made to solve these conventional problems, and even when it is attached to an electrical device, the operating member can be easily changed to a pull string or a knob as needed. The purpose is to obtain a switch device that can

[Means for Solving the Problems] The switch device according to the present invention has the functional parts installed outside the main body in which the functional parts related to circuit switching are incorporated, so that the circuits can be switched by pulling and the resulting return. An operating member mounting portion is provided which is internally connected to the operating member mounting portion, and the operating member mounting portion includes:
A rod-shaped knob serving as an operating member that is guided by a fixing holding member and can freely move up and down within the holding member is connected at its upper end, and the knob has an insertion member with a wide opening area at the upper end. A slit with a retaining part on the lower side is formed from the lower end to the middle part.

[Function] In this invention, a drawstring as an operating member provided with a knot can be freely attached to the knob using the slit without the need to replace parts.

[Embodiment] Fig. 1 and Fig. 2 both show a switch device as an embodiment of the present invention applied to a ventilation fan. That is, the switch device of this example has a main body 1 in which functional parts related to circuit switching are incorporated.
An operating member mounting portion 2 is provided on the outside of the device, and the circuit is switched by pulling and the resulting return.A rod-shaped knob 3 as an operating member that can move in the vertical direction is attached to the operating member mounting portion 2. It is connected and fixed at its upper end. The knob 3 has an insertion part 4 with a wide opening area at the upper end, and a slit 6 having a retaining part 5 at the lower part, extending from the lower end to the middle part. The knob 3 is guided by a holding member 7 fixed to a mounting portion such as the structure of a ventilation fan, and can move in the vertical direction within the holding member 7. Although the holding member 7 is a cylindrical sleeve in the illustrated example,
It may also be configured as an Ω-shaped metal fitting. In the free state of the slit 6 of the knob 3, the insertion portion 4 at the upper end thereof is hidden within the holding member 7, and is exposed to the outside when the knob 3 is moved downward by pulling.

In its original form, this switch device is of a knob type that is operated by pulling the knob 3; When worn, it becomes a pull string type that is activated by pulling the draw string 9. The drawstring 9 can be attached by inserting the knot 8 into the insertion part 4 of the slit 6 with the insertion part 4 exposed, and then pulling it downward. As a result, the knot 8 of the drawstring 9 is stopped by the stopper portion 5, so that it will not come off by pulling. The drawstring 9 can be easily removed by reversing the above procedure.

[Effects of the invention] As is clear from the above explanations based on the embodiments, the switch device of the present invention has a circuit that is connected to the outside of the main body in which functional parts related to circuit switching are incorporated by pulling and the resulting return. In order to switch, an operating member mounting portion internally connected to the functional component is exposed, and the operating member mounting portion is guided by a fixing holding member and can freely move up and down within the holding member. A rod-shaped knob serving as an operating member that can be operated is connected at its upper end side, and the knob has an insertion portion with a wide opening area at the upper end,
Since a slit with a retaining part on the lower side is formed from the lower end to the middle part, the slit can be used to attach the drawstring as an operating member with a knot freely to the knob without the need to replace parts. Even when attached to an electrical device, the operating member can be easily changed to a pull string or a knob as needed.
