PURPOSE:To provide a switch ready to hand in a bed constituted so as to be equipped with a lamp for night illumination. CONSTITUTION:A lamp 6 is attached to the top part of a casing 5 equipped with operation switches Sw1, Sw2 for raising and lowering the back, switches Sw3, Sw4 for raising and lowering a knee and operation switches Sw5, Sw6 for raising and lowering the whole of a bed part 2 and a lighting operation switch SwL for the lamp 6 is installed. The lighting operation switch SwL is turned ON to supply a lighting operation signal (current signal) to the transistor 7 of a lighting circuit 7 and the collector and emitter of the transistor 8 are brought to a continuity state to allow the lamp 6 to light. Since the lamp of a switch ready to hand can be allowed to approach a bed head stand or can illuminate the lower part of a bed by this constitution, a small articles can be easily taken out and action looking for something can be easily performed. |
