End cap switch for flashlight
View Patent ↗A switch apparatus for a flashlight includes a housing adapted to attach to a flashlight and defining an interior cavity. A processor is coupled to a first switch and a second switch. The first switch is user actuable and coupled to an input of said processor. The second switch is housed within said interior cavity and coupled to an output of the processor and is an electronically-controlled switch operable to selectively actuate the flashlight in response to actuation of said first switch. In a further aspect, a flashlight apparatus includes the switch apparatus and a flashlight.
1. A switch apparatus for a flashlight, comprising:
a housing adapted for removable attachment to a flashlight;
a processor coupled to a first switch and a second switch, said processor, said first switch, and said second switch received within said housing;
said first switch being user actuable and coupled to an input of said processor;
said second switch coupled to an output of said processor, said second switch being an electronically-controlled switch operable to selectively actuate the flashlight; and
said second switch selectively actuating the flashlight in response to actuation of said first switch.
2. The switch apparatus of claim 1 , wherein said first switch is a push button switch.
3. The switch apparatus of claim 1 , wherein said first switch is a normally open, momentary contact switch.
4. The switch apparatus of claim 1 , wherein said second switch is a semiconductor device.
5. The switch apparatus of claim 4 , wherein said second switch is selected from the group consisting of a transistor, a field effect transistor, and a metal oxide semiconductor field effect transistor.
6. The switch apparatus of claim 1 , wherein said processor includes control logic for controlling said second switch to actuate the flashlight when said first switch is actuated and to deactuate the flashlight when said first switch is deactuated.
7. The switch apparatus of claim 1 , wherein said processor includes control logic for controlling said second switch to allow operation of the flashlight in a continuously on mode of operation in response to a predetermined actuation sequence of the first switch.
8. The switch apparatus of claim 7 , wherein the first switch is a push button switch and said predetermined sequence is input by actuating said first switch twice in rapid succession.
9. The switch apparatus of claim 1 , wherein the flashlight includes a mounting member for removably attaching the flashlight to a firearm.
10. A flashlight apparatus, comprising a flashlight and a switch apparatus removably attachable to said flashlight, said switch apparatus comprising:
a housing adapted for removable attachment to a flashlight;
a processor coupled to a first switch and a second switch, said processor, said first switch, and said second switch received within said housing;
said first switch being user actuable and coupled to an input of said processor;
said second switch coupled to an output of said processor, said second switch being an electronically-controlled switch operable to selectively actuate said flashlight; and
said second switch selectively actuating said flashlight in response to actuation of said first switch.
11. The flashlight apparatus of claim 10 , wherein said housing is interchangeable with a battery compartment cover of said flashlight.
12. The switch apparatus of claim 1 , further comprising:
a power supply received within said housing and electrically coupled to said first switch and said processor.
13. The switch apparatus of claim 1 , wherein said housing is interchangeable with a battery compartment cover of the flashlight.
