Abstract

PURPOSE:To prevent the switch of electronic device from being on carelessly in a bag, by making the switching position of a specific switch lower than other switches. CONSTITUTION:The stopper member 7 is projected from the main body case 1 so that is surrounds the on-switch 4, and the upper surface is recessed in circular arc shape. Thus, when the on and off swithces 4, 5 and depressed externally, the off- switch reaches the effective stroke S, but the on-switch 4 is depressed only up to the convex part in circular arc of the stopper member 7, and since the stroke S' in this case is smaller than the effective stroke S, no device is on. Further, if desired, to be on, the recess of the member 7 is depressed to the index and the switch upper plane is depressed to the upper surface circular arc recess of the member 7, then the switch 4 reaches the effective stroke and power is supplied to the device.
