Abstract

The invention relates to a lighting control switch. The lighting control switch comprises a control unit used to control a lighting load, an illuminance setting unit of a manual operation component used to change operation amount in a preset range responding to manual operation of users, and a lower limit illuminance setting unit used to determine lower limit illuminance of the lighting load responding to manual input of users. The control unit is used to choose the illuminance according to operation amount and provide electricity corresponding to chosen illuminance for the lighting load. The control unit is used to choose the illuminance which is defined to be equal or higher than the lower limit illuminance as a regulated illuminance under the condition that the operation amount is lowest.

Description

technical field [0001] The present invention relates to a lighting control switch and in particular, to a lighting control switch for controlling power supplied to a lighting load. Background technique [0002] In the past, there has been proposed a lighting control switch installed in a corridor or a staircase and used to turn on and off a lighting load such as a corridor light or a stair light. Furthermore, there has been proposed a lighting control switch that turns on and off a lighting load installed in a bathroom and enables timer control of other loads such as a ventilation fan. This lighting control switch is disclosed in, for example, Document 1 (JP2008-4520A). [0003] The lighting control switch disclosed in Document 1 is provided on the front of the main body with a push operation unit for performing on / off operation of the lighting load, and a dimming time for setting a dimming time period for dimming the lighting load in a day segment setting unit.
