Problems solved by technology

However, in the case of a structure in which the excitation coil is connected to a different power supply, there is a possibility of wiring errors.
Furthermore, when a wiring error occurs, an excessive current may flow through the path through which the current flows to the exciting coil, and the switchgear may fail.

Embodiment Construction

[0016] Next, a switchgear according to one embodiment of the present invention and a load control system according to one embodiment of the present invention will be described in detail with reference to the drawings. In addition, in the following description, although the lighting load is illustrated as a load, the kind of load is not limited to a lighting load.

[0017] Such as Figure 6 As shown, the load control system of this embodiment has a switch device 1 and three remote control relays 2 (2A, 2B, 2C). However, in the following description, the symbols "2A", "2B" and "2C" are attached when the three remote control relays are distinguished, and the symbol "2" is indicated when the three remote control relays are not distinguished. Similarly, the symbols "4A", "4B", and "4C" are added when the three lighting loads are distinguished, and the symbol "4" is added when the three lighting loads are not distinguished.

[0018] The remote control relay 2 is conventionally kno...

Abstract

The present invention provides a switching device and a load control system, being able to restrain generation of fault because of false wiring. A polarity switching part (13) is provided with a built-in over current protection circuit (134); when the current output from a first output terminal (132) and a second output terminal (133) is greater than the upper limit value, a stop signal is output to a controller (131) from the over current protection circuit (134); and when the controller (131) receives the stop signal, all the field effect transistors of an H bridge circuit (130) are cut off to stop supply of the output current.

Description

technical field [0001] The present invention relates to a switch device and a load control system, in particular to a switch device for controlling lighting loads and the like and a load control system using the switch device. Background technique [0002] As a conventional example, a switch device described in Document 1 is exemplified (refer to Document 1 [Japanese Laid-Open Patent Publication No. 2012-174513]). This conventional example is configured to switch the supply and disconnection of electric power to a load via a power line, and is installed in a switch box embedded in a wall. [0003] In addition, this conventional example includes a relay unit and a control circuit for controlling the relay unit. The relay unit has electromagnetic relays and semiconductor relays. Electromagnetic relays, which are mechanical relays, consist of contacts and excitation coils. The contacts are configured as one-way make contacts in the power line. The excitation coil is install...
