Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a rotary switch used in a chandelier hanging light or other multi-light lighting equipment equipped with a plurality of electric lights.

[Prior Art] Rotary switches that can perform several stages of switching are often used as switches for multi-light lighting equipment such as chandeliers. A conventional rotary switch of this type is provided with a circular contact mounting surface 1 divided into eight equal parts in the circumferential direction, and with the axis of the contact mounting surface 1 serving as a fulcrum, as shown in FIG. A terminal member 2 is provided which is pivotally supported at the center, and the terminal member 2 is rotated arbitrarily in one direction one section at a time via a ratchet mechanism or the like in a state in which it is elastically opposed to the contact arrangement surface section 1. In addition, the contact arrangement surface part 1 has the following 180 degrees adjacent to the two sections 3a and 3b located 180 degrees opposite each other, which serve as non-contact parts for turning off the light.
Contact points a and 4a and 4b respectively at opposite positions
At the same time, a contact point a' is placed on one of the sections 5a, 5b at the next 180-degree opposing position adjacent to the sections 4a, 4b, and one of the remaining sections 6a, 6b at the remaining 180-degree opposing position adjacent thereto. and c are arranged so that both end pieces of the terminal member 2 can be connected to the contacts a, b or a', c at the same time or one at a time. In the case of a four-lamp lighting fixture as shown in the figure, two contacts a located at opposite positions
and b are connected to two different lights among the four lights, another contact a' is connected to one of the two lights, and the last contact c is connected to the miniature bulb, and the terminal member 2 is connected to one of the two lights. When rotated, 4 lights are lit - 2 lights are lit -
The cycle of turning on and turning off the light bulb is repeated twice.

[Problems to be solved by the invention] However, the rotary switch with the above structure requires that both ends of the terminal member have the same length to achieve the same effect, and that each contact is adapted to this. , especially because of the arrangement of some of the contacts for lighting,
In the case of partial lighting, the same bulbs, for example, the same two out of four bulbs, will always be lit, and some bulbs will wear out faster than others.

This invention was made in view of the above,
To provide a rotary switch capable of lighting several different lights in each cycle in the case of partial lighting.

[Means for Solving the Problems] In order to achieve the above object, the present invention configures a rotary switch for a lighting equipment as follows. That is, a terminal member is provided which resiliently contacts a circular contact arrangement surface made of an insulating material and is pivoted near one end of the intermediate portion with the axis of the contact arrangement surface as a fulcrum, and both end pieces of the terminal member are provided. The terminal is formed into a long terminal piece and a short terminal piece with different lengths from the fulcrum, and the contact mounting surface is divided into eight or more equal parts in the circumferential direction, and a pair of divisions facing each other at 180 degrees are divided into blanks for turning off the light. Two contacts _{a 1} , a 1 ′ and b ₁ , b _{1 ′} that contact both the long and short terminal pieces are arranged in the other pair of compartments located 180 degrees opposite each other, and the other 180 degrees Two contacts a ₂ , a ₂ ′ and b 2 , b _{2 ′} , which do not contact the short terminal piece but contact the long terminal piece, are arranged in a pair of opposing compartments, and the remaining 180
At least one pair of the sections at opposite positions is provided with one contact point _a3 and one contact _b3 , respectively, which do not contact the short terminal piece but contact the long terminal piece.

[Operation] The operation of the present invention will be explained using the case of a four-lamp type lighting fixture as an example. The contacts a ₁ , a ₂ , and a3 are connected to each other and connected to one lamp A ₁ of the four lamps. Contacts a ₁ ′ and a ₂ ′ are connected to each other and to another light A ₂ . Contacts b ₁ , b ₂ , b ₃ are connected to each other,
Connected to one other light _B1 . Contacts b ₁ ′ and b ₂ ′ are connected to each other and to the remaining one lamp B ₂ . One end of the power source is connected to the lamps and the other end of the power source is connected to the terminal member. The switch of this invention is
They are connected and used as described above.

When the long terminal piece and the short terminal piece of the terminal member are located in the section of the non-contact part of the contact arrangement surface part, the light is off.

When this long terminal piece is located in the section where it is connected to contacts a ₁ , a ₁ ′ or b ₁ , b ₁ ′, the short terminal piece is
Since the terminal members are located in sections 180 degrees opposite to each other, the terminal members are in a connected state with contacts a ₁ , a ₁ ′, b ₁ , b ₁ ′, and 4
All lights turn on.

When the long terminal piece is located in the section where it is connected to contacts a ₂ , a ² ′ or b ₂ , b ₂ ′, the short terminal piece is
They are located in sections 180 degrees opposite each other, so they do not come into contact with the terminals. Therefore, only two lights are lit and the other two lights are not lit. Moreover, the long terminal piece is the contact a ₂ ,
The light that is lit is different when the contact is connected to a ₂ ′ and when the contact is connected to b ₂ and b ₂ ′.

When the long terminal piece is located in the section where it is connected to contacts a ₃ or b ₃ , the short terminal piece does not come into contact with the terminal. Therefore, only one light is lit and the other three lights are not lit. Furthermore, the lights that are lit are different when the long terminal piece is connected to contact a ₃ and when it is connected to contact b ₃ .

Therefore, by rotating the terminal member, it is possible to switch between four lights on, two lights on, one light on, and off. Moreover, in the case of partially lighting two lights or one light, different lights are lit depending on the rotational position of the terminal member.

[Example] Next, an example of the present invention will be described based on the drawings. In the embodiment shown in FIGS. 1 to 3, 10
is a circular contact placement surface made of insulating material such as synthetic resin, and is divided into eight equal radial sections in the circumferential direction.
Usually, it is integrally molded with the casing 11. Reference numeral 20 denotes a terminal member pivotally supported starting from a shaft 12 inserted into the axis of the contact mounting surface 10, and extending from a position 180 degrees opposite to the circular central portion 21. Both end pieces are formed as a long terminal piece 22 and a short terminal piece 23 having different lengths from the fulcrum. This terminal member 20 is pressed toward the contact arrangement surface 10 by a spring 24, and the long terminal piece 22 and the short terminal piece 23 are provided so as to elastically come into contact with the contact arrangement surface 10. In case, long terminal piece 22
The short terminal pieces 23 are bent toward the contact arrangement surface 10 to ensure the above-mentioned contact. Further, the terminal member 20 can be sequentially rotated in one direction in units of sections of the contact mounting surface 10 via a ratchet mechanism or the like by rotating the operation plate 25 coaxially with the terminal member 25 at a predetermined angle. It is provided. The operation plate 25 is rotated by a switch string 26 connected thereto against the elastic force of the spring 24 serving as a return means. Of course, the terminal member 20 can also be rotated by means other than the above.

In the contact arrangement surface section 10, two sections 13a and 13b, which form a pair of 180-degree opposite positions among the 10 equally divided sections in the circumferential direction, are used as non-contact sections for turning off the light, and these two sections 13a , 13b adjacent to the next pair of sections 14a, 14 at 180 degrees opposite positions.
b has two contacts a ₁ , a ₁ ′ and b ₁ , respectively.
b ₁ ' is arranged so that it can contact the long terminal piece 22 and the short terminal piece 23 of the terminal member 20 at the same time. Also, the next pair of sections 15a and 15b adjacent to the sections 14a and 14b and located 180 degrees opposite each other
have two contacts a ₂ , a ₂ ′ and b ₂ , b ₂ ′, respectively,
It is arranged so that it can come into contact only with the long terminal piece 22. The next pair of sections 16a and 16b at 180 degrees opposite positions adjacent to these two sections 15a and 15b
, the contacts a3 and b3 are connected to the long terminal piece 2, respectively.
It is arranged so that it can only come into contact with 2. moreover,
Contacts c and c' that can contact only the long terminal pieces 22 are also arranged in the remaining pairs of sections 17a and 17b adjacent to the sections 16a and 16b and located 180 degrees opposite each other.

The contacts a ₁ , a ₂ , and a ₃ are connected to each other and have four lights.
One light among A ₁ , A ₂ , B ₁ , and B ₂ is connected to A1. Contacts a ₁ ′ and a ₂ ′ are connected to each other and connected to one other light.
Connected to A ₂ . Contacts b1, _b2 , _b3 are connected to each other and to one other light _B1 . Contact b ₁ ′,
b ₂ ′ are connected to each other and to the remaining one lamp B ₂ . Furthermore, contacts c and c' are connected to each other,
It is connected to one light bulb C. Instead of the contacts c and c', a contact capable of contacting both the long terminal piece 22 and the short terminal piece 23 may be arranged in one of the pair of sections 17a and 17b. Although not shown in the figure as a matter of course, the lights A ₁ , A ₂ , B ₁ , B ₂ and the miniature light C are connected via sockets. One end of the power source 30 is connected to those lights, and the other end is connected to the terminal member 20.

To explain the switch switching operation when the contacts are arranged and connected as described above, the terminal member 20 is rotated in one direction (counterclockwise in the drawing) by operating the switch string 26 etc. from the unlit state shown in the figure. When the sections are sequentially operated, in the first stage, the long terminal piece 22 and the short terminal piece 23 are connected to the two contacts a ₁ , a ₁ ′ and b ₁ , b ₁ ′, respectively.
All four lights A ₁ , A ₂ , B ₁ , and B ₂ are lit. In the second stage, only the long terminal piece 22 connects one of the two contacts a ₂ ,
A ₂ ' is connected, and the two lights A ₁ and A ₂ connected to these contacts light up. In the third stage, only the long terminal piece 22 is connected to the contact _a3 , and only one lamp _A1 connected to this contact lights up. Further, in the fourth stage, only the small bulb lamp C is lit, and in the fifth stage, it is turned off and one cycle is completed.

Then, in the next first stage, the long terminal piece 22 and the short terminal piece 23 are connected to the two contacts b ₁ , b ₁ ′ and a ₁ , a ₁ ′, respectively, and the four lights A ₁ , A ₂ , _B1 ,
B ₂ All lights up. In the second stage, long terminal piece 2
Only 2 is connected to the two contacts b ₂ and b ₂ ′,
Two lights B ₁ and B ₂ , different from those in the previous case, are lit. Also,
In the third stage, only the long terminal piece 22 has one contact b ₃
and one light connected to this contact.
Only B ₁ lights up. Further, in the fourth stage, only the miniature lamp C is turned on, and in the fifth stage, it is turned off and the next cycle is completed.

Therefore, with one rotation of the terminal member 20, 5-stage switching of 4 lights on - 2 lights on - 1 light on - miniature bulb on - lights off is one cycle, and two cycles are repeated, and moreover, two cycles are repeated, and moreover, two lights or a part of one light can be switched. In the case of lighting, different lights will be lit in the first cycle and the second cycle.

In addition, in the above embodiment, by changing the number of lights connected to each contact point, it can be used for switching multiple lights other than four lights in multiple stages. Also,
The number of sections of the contact arrangement surface section 10 may be set to an even number of 8 or more depending on the number of switching stages. For example, if there is no miniature lamp, the corresponding sections and contacts are not necessary.

[Effects of the invention] As described above, the present invention is capable of producing a multi-lamp type by using the difference in length between the long terminal piece and the short terminal piece of the terminal member, which is a switch piece, and the corresponding arrangement of the contacts. In lighting equipment, in addition to the conventional switching between 4 lights on, 2 lights on, miniature bulbs on, and lights out, it is possible to switch between 1 light on and 1 light on, and in addition, in the case of 2 lights on, or 1 light on, but only partially, It is possible to turn on different lights alternately in each cycle. Therefore, by using the switch of the present invention, the consumption of each light is approximately averaged, and the bulbs of each light can be replaced at about the same time, and there is no difference in the brightness of each light.

Therefore, the present invention is highly effective when used as a rotary switch for multi-lamp lighting equipment.
