  • Patent number: 9478371
    Abstract: An electrical switch and a flashlight employing the switch may comprise a base having three electrical conductors thereon and an electrically conductive flexible dome adjacent the base. The flexible dome has plural longer legs extending from its dome and in electrical contact with a first conductor, has a shorter leg extending from its dome and overlying a second conductor, and has its dome overlying a third conductor. A spring may extend from the base of the switch. A pushbutton may be moved to apply sufficient force to cause the shorter leg to contact the second conductor and the dome to contact the third conductor. A spring may be between the pushbutton and the flexible dome to couple force to the flexible dome.

  • Patent number: 8779683
    Abstract: An electronic circuit and/or method that determines a type and/or size of a battery in a light and controls operation of a light source may comprise: a circuit measuring the voltage of the battery; and a processor for determining the measured battery voltage. The processor may compare the measured battery voltage and a predetermined voltage and set an operating condition of the light source based upon the difference between the measured battery voltage and the predetermined voltage. The processor may apply a predetermined load to the battery for a predetermined time and measure battery voltage during the predetermined time; and determine the difference between the measured voltage of the battery and the measured battery voltage during the predetermined time.
