Claims Analysis

Total Claims: 11
Claim 1
Independent Claim 83 words
An illumination-type small-sized switch which comprises a switch case containing therein switch contacts; an actuator rockably positioned above said switch case; a light emitter disposed under said actuator for illuminating the same; and an insulating plate placed on the upper surface of said switch case for supporting said light emitter, said insulating plate having a circular opening and being formed on its upper surface with a resilient cylinder-shaped rising piece surrounding said opening, and said light emitter being fitted into said rising piece.
Claim 2
Dependent Claim 83 words
An illumination-type small-sized switch which comprises a switch case containing therein switch contacts; an actuator rockably positioned above said switch case; a light emitter disposed under said actuator for illuminating the same; and an insulating plate placed on the upper surface of said switch case for supporting said light emitter, said insulating plate having a circular opening and being formed on its upper surface with a resilient cylinder-shaped rising piece surrounding said opening, and said light emitter being fitted into said rising piece.
Claim 3
Dependent Claim 21 words
A switch as defined in claim 1, in which said rising piece is provided on its side surface with a fold.
Claim 4
Dependent Claim 21 words
A switch as defined in claim 1, in which said rising piece is provided on its side surface with a split.
Claim 5
Dependent Claim 30 words
A switch as defined in claim 1, in which said actuator is made of opaque material and has a window which is closed by a light-transmitting member detachably fitted thereon.
Claim 6
Dependent Claim 93 words
An illumination-type small-sized switch comprising a switch case containing therein switch contacts; an actuator rockably positioned above said switch case; a light-emitter disposed under said actuator for illuminating said actuator; lead wires from a source of electrical current to said light emitter; an insulating plate placed on the upper surface of said switch case and formed on its upper surface with a resilient rising piece which has a vertically penetrating bore, said light-emitter being fitted into said bore and the lead wire of said light-emitter being conducted out downwardly from said insulating plate.
Claim 7
Dependent Claim 93 words
An illumination-type small-sized switch comprising a switch case containing therein switch contacts; an actuator rockably positioned above said switch case; a light-emitter disposed under said actuator for illuminating said actuator; lead wires from a source of electrical current to said light emitter; an insulating plate placed on the upper surface of said switch case and formed on its upper surface with a resilient rising piece which has a vertically penetrating bore, said light-emitter being fitted into said bore and the lead wire of said light-emitter being conducted out downwardly from said insulating plate.
Claim 8
Dependent Claim 110 words
An illumination-type small-sized switch comprising a switch case containing therein contacts; an actuator rockably positioned above said switch case; a light emitter disposed under said actuator for illuminating the same; an insulating plate placed on the upper surface of said switch case for supporting said light-emitter by fitting the same into a hole of said plate; a leg piece projecting on the lower surface of said insulating plate adjacent said hole, the lead wire of said light-emitter being placed along the surface of said leg piece; and a conductor piece mounted on the switch case, the end portion of said lead wire being resiliently in contact with said conductor piece.
Claim 9
Dependent Claim 110 words
An illumination-type small-sized switch comprising a switch case containing therein contacts; an actuator rockably positioned above said switch case; a light emitter disposed under said actuator for illuminating the same; an insulating plate placed on the upper surface of said switch case for supporting said light-emitter by fitting the same into a hole of said plate; a leg piece projecting on the lower surface of said insulating plate adjacent said hole, the lead wire of said light-emitter being placed along the surface of said leg piece; and a conductor piece mounted on the switch case, the end portion of said lead wire being resiliently in contact with said conductor piece.
Claim 10
Dependent Claim 27 words
A switch as defined in claim 6, in which said leg piece has along its length a groove for guiding the lead wire of said light emitter.
Claim 11
Dependent Claim 31 words
A switch as defined in claim 6, in which said conductor piece is secured to the switch case together with a member for bearing a movable contact piece of the switch.
