ABSTRACT:
In a multiple pushbutton switch assembly, a flexible restoring tape has both ends affixed to the casing at both ends with a predetermined slack in such a manner that it is tensioned by depressing any one of the sliders which, when depressed, are locked alternately at a switch-on position and a switch-off position by elastic springs. The amount of the predetermined slack of the restoring tape corresponds to the amount of depression of each slider, so that when one slider is depressed, another one which has been depressed is restored or returned to its initial position, and only one slider is allowed to be depressed at any one time.
