BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wireless switch that receives an optical wireless signal and transmits the wireless signal to a wireless receiver that controls a load such as a lighting fixture.

0002

2. Description of the Related Art Generally, a load such as a lighting fixture is connected to a switch attached to a wall or the like via an electric wire. Therefore, it is necessary to carry out wiring work such as routing electric wires from the power supply wires on the ceiling through the wall to the switch, and it is necessary to perform wiring work in accordance with the progress of wall construction. Furthermore, since the electric wires are buried in the wall surface, conduit pipes, switch boxes, etc. are required, and construction requires time and skill.

[0003] In contrast, a load control system has been proposed that eliminates the need to run electric wires from the ceiling to a switch and controls loads disposed on the ceiling or the like using wireless signals. As shown in FIG. 8, this load control system includes a wireless receiver X that receives wireless signals and turns on and off switching elements such as relays, and a wireless receiver It is equipped with a wireless switch Y. The wireless receiver Y is disposed on the ceiling or the like, and a switch element such as a relay is inserted between the power supply and the load L, and the wireless switch Y sends out a wireless signal such as infrared rays to turn on and off the switch element. The wireless switch Y is attached to a wall within a range where the wireless receiver X can receive wireless signals, or is kept at hand and used as a so-called remote control device.

[0004] The structure for attaching the wireless switch Y to a wall or the like is to hook the head of a hook, such as a nail or screw, protruding from a construction surface such as a wall through a hook hole provided on the back of the case. is being considered.

[0005]

[Problems to be Solved by the Invention] With the above structure, if the wireless switch Y is attached to a construction surface such as a wall, the head of the hook will be exposed when the case is removed from the construction surface. There is a problem of damaging the Also,
In order to prevent the case from tilting when it is attached to the construction surface, it is necessary to provide multiple hooks, so it is necessary to adjust the position of the hooks such as nails and screws on the case. There is a problem in that it is necessary to precisely match the position of the hole, making construction time-consuming.

[0006] The present invention aims to solve the above-mentioned problems, and the case is installed through a mounting plate having a plurality of hook pieces whose positional relationships with respect to the plurality of hook holes provided in the case are set in advance. By attaching it to a surface, the wireless switch eliminates the need for positioning hooks as required in the past, making installation easier, and also prevents the aesthetic deterioration caused by nails and screws being exposed when the case is removed. This is what we are trying to provide.

[0007]

[Means for Solving the Problems] In order to achieve the above object, the present invention provides a wireless switch that transmits a wireless signal to a wireless receiver that receives an optical wireless signal and controls a load. Constructed using a case that has a switch operation part on the front and a signal transmission window that transmits wireless signals to key points around the periphery, and fixing devices such as screws that are inserted into multiple mounting holes from the front side. A mounting plate is fixed to the surface, and the front surface of the mounting plate is provided with a plurality of hook pieces that protrude forward and the tips thereof protrude upward, and the back surface of the case is provided with a plurality of hook pieces that are engaged with the hook pieces. A hook hole is formed in the mounting plate to removably connect the case.

[0008]

[Operation] According to the above structure, the case is detachably attached to the construction surface via the mounting plate fixed to the construction surface such as a wall, and the front surface of the mounting plate has a wall that protrudes forward. At the same time, a plurality of hook pieces whose tips protrude upward are provided, and a plurality of hook holes are formed on the back of the case to engage with each hook piece and removably connect the case to the mounting plate. Therefore, if the positional relationship of the hooking pieces is managed during the manufacturing of the mounting plate, construction can be carried out at the construction site without considering the positional relationship of the hooking holes of the case, making the construction easier. In addition, since the hook pieces are pre-formed on the mounting plate, a superior appearance can be achieved compared to when nails or screws are used as hooks at the construction site.

That is, a light receiving element PD made of a photodiode or the like that receives a wireless signal in the form of infrared rays is provided, and the output of the light receiving element PD is input to a signal processing circuit 62 through a light receiving circuit 61 that performs amplification and waveform shaping. The signal processing circuit 62 drives a relay Ry, which is a latching relay, via a relay drive circuit 64 in accordance with the control content of the wireless signal, and opens and closes a contact r, which is a switch element. The signal processing circuit 62 has a microprocessor as its main component, and is initialized by a reset signal output from a reset circuit 65 when the power is turned on, and is synchronized with a clock signal output from a clock signal generation circuit 66. It works. Furthermore, power is supplied to each part of the wireless receiver by a power supply circuit 66 that stabilizes the rectified output obtained by rectifying the commercial AC power supply AC by a full-wave rectifier circuit RE. A contact r of the relay Ry is inserted between a terminal T1 to which a commercial alternating current power supply AC is connected and a terminal T2 to which a load L is connected.

With the above configuration, in the wireless receiver, the switches SW1 and SW of the wireless switch

If you change the processing content of the signal processing circuit 62 of the wireless receiver, you can temporarily turn on the load L for a certain period of time after turning on the switches SW1, SW2, and SW3, or turn off the switches SW1, SW2, and SW3. An operation such as a delayed off operation in which the load L is turned off after a certain period of time has passed after the operation is also possible.
