Abstract

PURPOSE:To easily allow a user to added or release remote control function and automatic control function as required by providing 1st and 2nd connection terminals respectively to both ends of a series circuit comprising a local switch in series with a load main body and providing a 3rd connection terminal to the other end of the mode changeover switch whose one terminal is connected to one of the connection terminal. CONSTITUTION:The 1st and 2nd connection terminals 3a, 3b are provided respectively to both ends of the series circuit being the series connection of the load main body 1a and the local switch 2. Then the 3rd connection terminal 3c is provided to the other end of the mode changeover switch 4 whose one end is connected to the one connection terminal 3b. Then the control adaptor incorporating the control circuit 5 applying remote control or automatic control to the load device is mounted attachably detachably to/from the load device 1. In case of operating the load device by the local control mode, the control adaptor 6 is not loaded. On the other hand, in case of operating the load device in the remote control mode or the automatic control mode, while the local switch 2 is turned on, the control adaptor 6 has only to be mounted to the end face of the load device 1.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a load device with a control mode switching function that can be operated in remote control or automatic control mode as appropriate.

[Conventional technology] Conventionally, loads such as lighting equipment that are turned on and off by hand switches can be remotely controlled from a central control panel, or automatically controlled by EE switches, heat sensors, heat sensors, etc.
．． t. Cut the wiring of the power supply circuit of the load device and insert the output contact of the control circuit in series with the load body, or change the power supply wiring connected to the power terminal and connect the output contact of the control circuit to the load body. It was necessary to insert them in series.

[Problems to be Solved by the Invention] However, in the above-mentioned conventional example, it was necessary to change the wiring of the power supply circuit section of the load device in order to add and cancel the remote control function and automatic control function. Therefore, in addition to the local AM function, there is a problem in that the user cannot easily provide a remote control function or automatic control function or cancel additional functions as needed.

The present invention has been made in view of the above points, and its purpose is to enable the user to remotely control W as needed.
! One object of the present invention is to provide a load device with a control mode switching function that can easily add and cancel an automatic control function.

[Means for Solving the Problems] The light load device with a control mode switching function of the present invention has a first switch connected at both ends of a series circuit in which a hand switch is connected in series to the load main body. A second connection terminal is provided, and a third connection terminal is provided at the other end of a mode changeover switch whose one end is connected to one connection terminal.

[Function] The present invention is configured as described above, in which a mode changeover switch is further connected in series to a series circuit in which a hand switch is connected in series to the load body, and a mode changeover switch is connected to both ends of the series circuit and to the series circuit. A connection terminal is provided at each end of the switch, and a 711 source is connected to both ends of the series circuit of the load body, the hand switch, and the mode changeover switch, and the control mode can be changed by turning the mode changeover switch on and off. It can be switched to control mode or external control mode, allowing the user to easily add or cancel remote control or automatic control functions as needed without changing the wiring of the power supply circuit. .

[Embodiment 1] Figures 1 to 3 show an embodiment of the present invention, in which a first . Second connection terminals 3 a and 3 b are provided, and a third connection terminal 3 c is provided at the other end of the mode changeover switch 4 whose one end is connected to one connection terminal 3 ( ). If so, a control adapter 6 incorporating a control circuit 5 for remotely or automatically controlling the load device 1 can be attached to the load device 1, and the load device r!11 can be operated in a remote control or automatic control mode as appropriate. A normally closed mode changeover switch 4 that is turned off when the control swallower 6 is installed is provided in the load device 1, and the output contact 5a of the control circuit 5 and the power terminal are connected to the connection terminals 3a to 3a.
Connection pins 7a to 7c, which are respectively connected to the control adapter 3c, are provided in a protruding manner on the control adapter 6. Here, when the control adapter 6 is attached to the load device 1, the mode changeover switch 4 is turned off and the output contacts 5a are connected to both ends of the mode changeover switch 4. In the embodiment, the mode changeover switch 4 is formed of a normally closed contact consisting of a movable contact plate 10 and a fixed contact plate 11, and has a pressing piece 8 protruding from the case end face of the control adapter 6. is insertion hole 1
4, and when the movable contact plate 10 is pressed by the suppressing piece 8, the movable contact 10a is separated from the fixed contact 11a and turned off.

The operation of the embodiment will be described below. If the load device 1 is to be operated in the hand control mode, the control adapter 6 may not be attached; in this case, since the normally closed mode selector switch 4 is turned on, the connection terminal 3 a , 3c is applied to the load main body IIL via the hand switch 2, and the load device 1 is manually turned on and off by the hand switch 2, allowing operation in the hand control mode. On the other hand, when operating the load device 1 in remote control mode or automatic control mode, the control adapter 6 may be attached to the end face of the load device 1 with the hand switch 2 turned on. When the mode changeover switch 4 is turned off, the output contact 5a of the control circuit 5 is connected to both ends of the mode changeover switch 4, and the load device 1 is connected to the output contact 5a of the control circuit 5.
It can be turned on and off by remote control or automatic control mode. Note that if a failure occurs in the control circuit 5 and the load device 1 cannot be controlled in remote control or automatic control mode, the control adapter 6 can be removed and the load device 1 can be controlled in the local control mode. It is possible to prevent problems from occurring even if repairs take time.

As described above, in this embodiment, the mode changeover switch 4 is turned off and the output contact 5a of the control circuit 5 of the control adapter 6 is connected to the connection terminals 3b at both ends of the mode changeover switch 4,
3c, the control mode of the load device 1 can be switched from the local control mode to the external control mode (remote control or automatic control) without changing the wiring of the power supply circuit section. That is, the user can easily add or remove the remote control function and automatic control function as needed without changing the wiring of the power supply circuit section.

FIG. 4 and FIG.
58 to turn off the mode switching switch 4. Lock pieces 15 are provided above and below the mounting surface of the control adapter 6 to prevent it from falling off. The control adapter 6 is reliably attached to the end surface of the load device 1 by engaging the end portion of the control adapter 6 in a concave and convex manner. Note that the connecting pins 7a to 7C may be formed in the shape of blades, and the blade holders of the connection terminals 3a to 3C may be formed of metal fittings.
