Description

Detailed Description of the Invention

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a switch device,
More specifically, for example, the present invention relates to a switch device for blinking and dimming a light source such as an electric light in a building.

2. Description of the Related Art Conventionally, in a switch for blinking an electric light in a building, each switch arranged on a wall surface or the like and connected to each electric light is individually turned on or off. Further, when the electric lights arranged above and below the stairs of a building or in a long corridor are blinked, a switch device 30 as shown in FIGS. 5 and 6 has been put into practical use. This switch device 30 is, for example, a stairwell 2
1, the electric light L arranged on the ceiling 22 on the second floor is turned on or off on the first floor and the second floor, respectively.
That is, the switch device 30, as shown in FIG.
First-floor switch 31 connected to AC100V household power supply
And a second-floor switch 32 connected between the first-floor switch 31 and the electric lamp L, which is a so-called three-way switch. According to the switch device 30, the electric lamp L can be turned on or off by operating either the first floor switch 31 or the second floor switch 32.

However, in the case of the switch device 30 described above, normally three wirings are required between the first-floor switch 31 and the second-floor switch 32, which complicates the wiring work and causes the wiring to be color-coded. There is a problem that the wiring work is extremely complicated, such as that the wiring is concentrated on one side of the first floor switch 31 or the second floor switch 32. The complexity of such wiring work is 3 when the number of switches is 2 as described above,
It becomes more remarkable as the number increases to four. Therefore, it is an object of the present invention to provide a switch device capable of facilitating and simplifying the wiring work by improving the elements for blinking and dimming the light source.

A switching device of the present invention is connected between a power source and a light source, and a main switch section for blinking and dimming the light source, and a main switch section connected in parallel with each other for a light source of the main switch section. It has an arbitrary number of auxiliary switch units that indirectly control the blinking and dimming operations.

According to this switch device, the main switch units for blinking and dimming the light source are indirectly controlled by an arbitrary number of auxiliary switch units connected in parallel with each other. Wiring between the two can be performed with a wiring cable having a two-piece structure, which facilitates and simplifies the wiring work.

EXAMPLES Examples of the present invention will be described in detail below. The switch device 1 shown in FIGS. 1 and 2 is a building 2 similar to the conventional example.
0, for example, in the stairwell 21
The electric lamp L arranged in No. 2 is capable of blinking and dimming on the first floor and the second floor, respectively. This switch device 1 has an AC1
Main switch unit 2 which is connected to a 00V household power source and which controls the flashing and dimming of the light L arranged on the ceiling 22 on the second floor, and the first auxiliary arranged on the wall surface on the first floor of the stairwell 21 of the stairwell 21 of the building 20. A switch part 3 and a second auxiliary switch part 4 arranged on the wall surface on the second floor of the staircase 21 are provided, and the first auxiliary switch part 3 and the second auxiliary switch part 4 are connected in parallel, The auxiliary switch sections 3 and 4 are configured to indirectly control the blinking and dimming operations of the main switch section 2 with respect to the electric lamp L. As shown in FIG. 2, the main switch unit 2 includes a main switch 5 connected in series to a household power source of AC100V, and a dimming unit 6 connected between the main switch 5 and the electric lamp L. .. As shown in FIG. 3, the dimming unit 6 includes a pulse motor 7, a contact piece 9 fixed to a rotary shaft 8 of the pulse motor 7 and rotating together with the rotary shaft 8, and sequentially with the rotation of the contact piece 9. A total of four contacts 1 that contact the contact piece 9

b, a voltage controller 11 connected to the contacts 10b and 10c via a resistor Rc, and the voltage controller 1 associated with the contact between the contact piece 9 and the contacts 10a to 10d.
This voltage controller 1 according to the difference of the input resistance to 1
1, the lighting state of the electric lamp L is 4 of bright, medium, dark and extinguished.
It is designed to switch to the type. Each of the first auxiliary switch unit 3 and the second auxiliary switch unit 4 has an operation piece 1 on the surface of the box 12, as shown in FIGS.
3 is rotatably mounted, and the pulse motor 7 is installed inside the box 12 in accordance with the rotational position of the operation piece 13.
Different kinds of pulse signals to the pulse motor 7
The pulse generator 14 is provided to bring the contact piece 9 into contact with any of the contacts 10a to 10d. Further, the first auxiliary switch unit 3 and the second auxiliary switch unit 4 are
The two connection cables 15 are connected in parallel. According to the switch device 1 having the above-described configuration, for example, when the operator operates the operation piece 13 of the first auxiliary switch unit 3 on the first floor to the bright position, the pulse generation unit 14 outputs a pulse corresponding to the bright position. A signal is sent to the pulse motor 7. The pulse motor 7 brings the contact piece 9 into contact with the contact 10a to which no resistor is connected, based on the pulse signal.
As a result, the voltage controller 11 turns on the electric lamp L in a bright state. Further, when the operator operates the operation piece 13 of the first auxiliary switch section 3 on the first floor to the dark position, the pulse generating section 14 sends a pulse signal corresponding to the dark position to the pulse motor 7. The pulse motor 7 connects the contact piece 9 to the contact 10c to which the resistor Rc is connected based on the pulse signal. As a result, the voltage controller 11 turns on the electric lamp L in a dark state. Further, when the operation piece 13 is operated to the off position, the pulse generator 1
The pulse signal corresponding to the position where 4 is off is applied to the pulse motor 7
Send to. The pulse motor 7 brings the contact piece 9 into contact with the contact 10d based on the pulse signal. As a result, the voltage controller 11 turns off the light L. In the second auxiliary switch section 4 on the second floor, the dimming and extinction of the electric lamp L can be performed as in the case described above. Further, since the first and second auxiliary switch portions 3 and 4 are connected in parallel by the two-connection cable 15, the first and second auxiliary switch portions in the wiring work of the switch device 1 are performed. The connection between 3 and 4 is extremely simple, and there is no need to color-code the wiring, and the wiring work can be simplified and facilitated as compared with the conventional example. Also, the connection cable 15
Since only the main switch section 2 is controlled, a thin wire for a weak current can be used, and the wiring can be made inconspicuous. In addition, as the light control unit 6 described above,
