Are arranged facing each other, and a light-transmitting cover 7 is covered on the front opening. A large operation handle 5 formed to a size that covers substantially the entire mounting frame on one side of the two mounting frames 3 is swingably mounted on a switch portion formed on the right side of the front surface of the case 1. When the operation switch 5 is pressed against the resilient force of the return spring 6, the microswitches SWa and SWb are pressed via the operation piece 4, and either of them is turned off. I have.

Here, as shown in FIG. 4, the operation piece 4 is a pair of micro switches SW mounted on the printed circuit board 2b.
a, SWb are provided at both ends of the micro-switch SW.
a, while being brought into contact with SWb, the return spring 6 made of a coil spring is elastically urged toward the front side of the case 1. Further, on the front side of the operation piece 4, a fitting recess 4 b is provided which is concavely and convexly fitted with a fitting projection 5 a protruding from the back side of the operation handle 5. The operation handle 5 is attached to the operation piece 4 by concave and convex fitting with the place 4b. That is, if the operation handle 5 is pressed against the elastic force of the return spring 6, the operation piece 4 is pressed, and as a result, the protrusion 4a protruding from the operation piece 4 presses the micro switches SWa and SWb. Will be. In this case, even if the pressing operation of the operation handle 5 is not appropriate (even if the operation handle 5 is pressed in an inclined state), no excessive stress is applied to the switch mechanism, and
Since one of the micro switches SWa and SWb is turned off, the operability is improved and the load control can be reliably performed.

The operation display light emitting diodes LDa and LDb (red → on, green → off) are exposed at the center of the switch section.
Operation display is performed via a slit 5a of the operation handle 5 provided at a position facing the LDb. In the figure, reference numeral 9 denotes a quick connection terminal to which a power supply line or a load line is connected.

Therefore, even when a plurality of optical wireless receivers are arranged in the same room, load control can be separately performed. Since the operation portion of the address setting switch SWc is covered by the operation handle 5 except when the unique address is set, it is possible to prevent the unique address from being changed carelessly. Further, the light emitting diodes LDa and LDb for operation display are turned on and off by the auxiliary relay contact rb which is turned on and off in conjunction with the main relay contact ra, so that the operation state of the load RL can be easily visually recognized. . Further, a pair of microswitches S
Wa, SWb, and a hand-operated switch for forcibly inverting the latching relay RY is provided.
By pressing the operation handle 5 without using the optical wireless transmitter, the load RL can be controlled, and the usability can be improved. In addition, since the optical wireless receiver is a two-unit module and the light receiving module PDM and the hand-operated switch unit are arranged side by side, it can be easily arranged using two embedded boxes, and the usability is improved.
