Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
120 words
A push-button switch comprising; an illumination unit accommodating therein a light emitting element such as a LED or the like; a lamp holder for holding said light emitting element, in the outer periphery of which is formed a projection; a lamp casing for accommodating said lamp holder therein, in the inner face of which is formed with a recessed portion corresponding to said projection, while in the outer face of which is formed with a projected shaft; a plunger having an engaging portion at its one end which is engaged with said projected shaft of the lamp casing; and a housing which accommodates said lamp casing in such manner as to be able to be depressed by a given stroke.
Claim 2
Dependent Claim
120 words
A push-button switch comprising; an illumination unit accommodating therein a light emitting element such as a LED or the like; a lamp holder for holding said light emitting element, in the outer periphery of which is formed a projection; a lamp casing for accommodating said lamp holder therein, in the inner face of which is formed with a recessed portion corresponding to said projection, while in the outer face of which is formed with a projected shaft; a plunger having an engaging portion at its one end which is engaged with said projected shaft of the lamp casing; and a housing which accommodates said lamp casing in such manner as to be able to be depressed by a given stroke.
Claim 3
Dependent Claim
124 words
A push-button switch comprising; an illumination unit accommodating therein a light emitting element such as a LED or the like; a lamp holder for holding said light emitting element, in the outer periphery of which is formed a U-shaped projection; a lamp casing for accommodating said lamp holder therein, which is integrally formed with an engaging projection corresponding to a grooved portion of said U-shaped projection such that said U-shaped projection is secured to said engaging projection; and a housing which accommodates said lamp casing in such manner as to be able to be depressed by a given stroke, and which is integrally formed with a forked engaging member such that said U-shaped projection is secured to said engaging member from opposite sides thereof.
Claim 4
Dependent Claim
124 words
A push-button switch comprising; an illumination unit accommodating therein a light emitting element such as a LED or the like; a lamp holder for holding said light emitting element, in the outer periphery of which is formed a U-shaped projection; a lamp casing for accommodating said lamp holder therein, which is integrally formed with an engaging projection corresponding to a grooved portion of said U-shaped projection such that said U-shaped projection is secured to said engaging projection; and a housing which accommodates said lamp casing in such manner as to be able to be depressed by a given stroke, and which is integrally formed with a forked engaging member such that said U-shaped projection is secured to said engaging member from opposite sides thereof.
Claim 5
Dependent Claim
