Abstract
Herein disclosed is an illuminated push-button switch structure in which, when the push button is pushed, the push-button guide member united to the button is depressed while being supported to slide by the switch base. Then, the switch lever of the switch mechanism associated with the push-button guide member is abruptly turned back with a predetermined depression stroke to afford a switching feel. This turn prevents further movement of the push button in a predetermined depression direction in order to eliminate any undesired vibration of the push button. Even if the push button is obliquely pushed, it is always prevented from being inclined to provide the stable switching operation at all times.
