Abstract

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.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 115 words
An illuminated push-button switch structure comprising: a push button mounted in the front side of a machine; a push-button guide member for guiding the depression of said push button in a predetermined direction; a switch mechanism including switch levers that restore the depressed push button to its normal state to give a switching feel; a switch adapted to be operated by said switch mechanism; an indicator for indicating the switch input information of said switch through illumination; a stationary substrate mounting said indicator and said switch thereon; a switch base supporting not only said push-button guide member slidably but also said switch mechanism and said stationary substrate, and a switch case accommodating said switch base.
Claim 2
Dependent Claim 115 words
An illuminated push-button switch structure comprising: a push button mounted in the front side of a machine; a push-button guide member for guiding the depression of said push button in a predetermined direction; a switch mechanism including switch levers that restore the depressed push button to its normal state to give a switching feel; a switch adapted to be operated by said switch mechanism; an indicator for indicating the switch input information of said switch through illumination; a stationary substrate mounting said indicator and said switch thereon; a switch base supporting not only said push-button guide member slidably but also said switch mechanism and said stationary substrate, and a switch case accommodating said switch base.
Claim 3
Dependent Claim 51 words
An illuminated push-button switch structure according to Claim 1, wherein said push button includes stepped legs extending from the two side walls thereof and having engagement holes, and wherein said button guide member has engagement projections made engageable with said engagement holes and stepped retaining portions made engageable with said legs.
Claim 4
Dependent Claim 76 words
An illuminated push-button switch structure according to Claim 1, wherein said switch mechanism includes: a first lever adapted to be depressed through said button guide member when said push button is pushed; a second lever adapted to be turned back when said first lever is depressed to a predetermined position; and a return spring sandwiched between said first and second levers for returning the first and second levers to their initial positions after the switching operation.
