The cap is designed to give faster and more convenient access to light in an emergency, or when needed. The end cap connects to the inner conductor with a castled shape that allows the conductors to be moved in or out alignment to allow or prevent contact. The gasket or washer provides insulation and spacing of the conductors. Side forces on the end cap overcome the spacing of the washer to make electrical contact. The end cap may also support a glass breaking device. The glass breaker is a hardened tip on the end of the cap. ## Claims ### Claim 1 An switch for a flashlight comprising: an upper switch body containing a first conductive ring; a lower switch body containing a second conductive ring; said first conductive ring and said second conductive ring being biased to a concentric axis with a compliant tubular component that normally prevents a conductive path between said first conductive ring and said second conductive ring, and said upper switch body and said lower switch body are slidably positionable to create axial and or angular displacement to allow electrical conductivity between said first conductive ring and said second conductive ring. ### Claim 2 (depends on 1) The switch for a flashlight according to claim 1 that further includes an angular component that is secured to said compliant tubular component that is constrained to slide in a first direction upon said lower switch body. ### Claim 3 (depends on 2) The switch for a flashlight according to claim 2 wherein said angular component that is restrained from rotation in a first direction on said lower body. ### Claim 4 (depends on 3) The switch for a flashlight according to claim 3 wherein said angular body maintains indexed orientation to said lower body by means of orienting a portion of said tubular component with an angular protruding feature that is indexed to engage in a recess in said upper switch body. ### Claim 5 (depends on 4) The switch for a flashlight according to claim 4 wherein further includes a sliding cam. ### Claim 6 (depends on 5) The switch for a flashlight according to claim 5 that further includes a sliding body. ### Claim 7 (depends on 6) The switch for a flashlight according to claim 6 wherein said sliding cam has an angular surface that interacts with said upper switch body to allow rotation in a first direction of said upper switch body to force said sliding body from said restrained engagement with said upper switch body thereby allowing an off axis switch function. ### Claim 8 (depends on 7) The switch for a flashlight according to claim 7 whereby continued rotation of said upper body displaces at least one of said first conductive ring or said second conductive ring to make electrical contact together. ### Claim 9 (depends on 8) The switch for a flashlight according to claim 8 whereby sliding said tubular component in a second direction towards said upper switch body applies a caming force that rotates said upper switch body away from a camed axil offset that allows said first conductive ring and said second conductive rings to being biased to a concentric axis whereby being electrically isolated. ### Claim 10 (depends on 9) The switch for a flashlight according to claim 9 whereby continued sliding of said sliding body captures said upper switch body on a diameter that restrains said tubular component on a concentric axis. ### Claim 11 (depends on 10) The switch for a flashlight according to claim 10 wherein said sliding lock is restrained to lower switch body in a fashion that allows limited sliding movement while restraining said sliding body from rotation in a first direction on said lower switch body. ### Claim 12 (depends on 1) The switch for a flashlight according to claim 1 that further includes a connection from said first inner switch body and said second inner switch body to a control circuit. ### Claim 13 (depends on 12) The switch for a flashlight according to claim 12 wherein when said electrical connection from said control circuit is continuous. ### Claim 14 (depends on 12) The switch for a flashlight according to claim 12 wherein when said electrical connection from said control circuit is intermittent. ### Claim 15 (depends on 12) The switch for a flashlight according to claim 12 wherein a duration of making electrical contact effects operation of said control circuit. ### Claim 16 (depends on 2) The switch for a flashlight according to claim 2 wherein a number of making electrical contacts effects operation of said control circuit. ### Claim 17 (depends on 1) The switch for a flashlight according to claim 1 that further includes a compliant conductor that is a spring loaded ball or pin. ### Claim 18 (depends on 1) The switch for a flashlight according to claim 1 wherein said outer switch body further includes an embedded glass breaker. ### Claim 19 (depends on 14) The switch for a flashlight according to claim 14 wherein said outer switch body has a dual angle step to said glass breaker. ### Claim 20 (depends on 1) The switch for a flashlight according to claim 1 wherein said emergency switch is incorporated into the illuminating end of the flashlight.
