PURPOSE:To improve the external appearance of a transmitter and to make it possible to handle the transmitter with one hand by forming plural recessed parts having circular arc-like cross sections on the outer surface of the transmitter body and arranging a part of the operation part of a push-button switch in each recessed part. CONSTITUTION:Three circular recessed parts 16 having circular arc-like cross sections are formed on the outer surface of the body 15 of the transmitter 10 and dimmer control push-button switches 12, 13 and a full lighting push-button switch 14 are arranged on the recessed parts 16 so that parts of operation parts 12a to 14a are positioned in respective recessed parts 16. The other parts of the operation parts 12a to 14a of the switches 12 to 14 are inserted into grooves 17 formed adjacently to respective recessed parts 16 so as to be vertically moved. On the other hand, the operation part 11a of an ON/OFF switch 11 is embedded in a circular hole formed on the outer surface of the body 15 so as to be vertically moved. In this constitution, the whole transmitter can be thinned, so that the external appearance of the transmitter can be improved and single hand operation can be attained. |
