Abstract
Abstract The invention relates to a switching device adapted for use in instruments of personal defence to actuate two or more electrically or mechanically operated components of which at least one is electrically operated and at least one is mechanically operated. The device may be adapted for use in conjunction with the push button system of a torch, the push button system being operable both partially so as to actuate only the circuit for a bulb, and fully so as to actuate also a noise alarm device and mechanically actuate means capable of emitting a spray jet.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
86 words
A personal defence device comprising: a hand-held casing; a plurality of operable components comprising: means for producing a noise alarm located within the casing; and an aerosol spray can located within the casing to project a spray of a fluid from the device; and an operating button carried by the casing and manually shiftable relative to the casing to and from a first position wherein neither of said components are operated; and a second position wherein both of said components are operated by the operating button.
Claim 2
Dependent Claim
86 words
A personal defence device comprising: a hand-held casing; a plurality of operable components comprising: means for producing a noise alarm located within the casing; and an aerosol spray can located within the casing to project a spray of a fluid from the device; and an operating button carried by the casing and manually shiftable relative to the casing to and from a first position wherein neither of said components are operated; and a second position wherein both of said components are operated by the operating button.
Claim 3
Dependent Claim
66 words
A device according to claim 1 wherein said aerosol spray can includes a spray button to actuate the spray when depressed, said means for producing a noise alarm comprises an aerosol operated whistle actuated by depression of the whistle towards aerosol can, and wherein said spray button and whistle are depressed by virtue of movement of said operating button from said first to said second position.
Claim 4
Dependent Claim
184 words
A personal defence device comprising: a hand-held casing; a plurality of operable components including; an electric light bulb carried by the casing to project a light beam from the device; an aerosol spray can located within the casing to project a spray of a fluid from the device, and means for producing a noise alarm located within the casing; a source of electrical power located within the casing; an electric circuit including switch means within the casing to energize said light bulb from said source when said switch means is closed. a spray button attached to said aerosol spray can to actuate said spray by depression of said button; and a multiposition operating button carried by the casing and manually shiftable relative to the casing sequentially from a first position wherein none of said components are operated, to a second position in which said switch means is closed by the operating button to energize said electric light bulb, to a third position in which said switch means remains closed, said spray button is depressed and said noise alarm is operated by the operating button.
Claim 5
Dependent Claim
184 words
A personal defence device comprising: a hand-held casing; a plurality of operable components including; an electric light bulb carried by the casing to project a light beam from the device; an aerosol spray can located within the casing to project a spray of a fluid from the device, and means for producing a noise alarm located within the casing; a source of electrical power located within the casing; an electric circuit including switch means within the casing to energize said light bulb from said source when said switch means is closed. a spray button attached to said aerosol spray can to actuate said spray by depression of said button; and a multiposition operating button carried by the casing and manually shiftable relative to the casing sequentially from a first position wherein none of said components are operated, to a second position in which said switch means is closed by the operating button to energize said electric light bulb, to a third position in which said switch means remains closed, said spray button is depressed and said noise alarm is operated by the operating button.
Claim 6
Dependent Claim
19 words
A device according to claim 1 wherein said means for producing a noise alarm comprises an aerosol operated whistle.
Claim 7
Dependent Claim
39 words
A device according to claim 1 wherein the direction of the movement of said operating button from the second to third position is substantially at right angles to the direction of its movement from the first to second position.
Claim 8
Dependent Claim
50 words
A device according to claim 3 wherein said means for producing a noise alarm comprises an electrically operated buzzer energized from saId source of electrical power by an electric circuit including a second switch means and said second switch means is closed by the operating button in said third position.
Claim 9
Dependent Claim
50 words
A device according to claim 3 wherein said operable components further include a radio transmitter energized from a second source of electrical power located within the casing by an electric circuit including third switch means and said third switch means is closed by the operating button in said third position.
Claim 10
Dependent Claim
45 words
A device according to claim 7 wherein said radio transmitter has a telescopic aerial normally entirely located in the casing but releasable to extend out of the casing, and said aerial is released only by the shifting of said operating button into the third position.
