  • Patent number: 8210710
    Abstract: A flashlight is described holding at least one battery and an illumination source. A circuit interruption and completion device is provided forming a complete circuit between the illumination source and the battery, when the device is in a closed mode. The device comprises a switch which is manually actuated between at least a first position which causes the device to enter the closed mode and a second position. A switch holding structure comprises a member with means for making an electrical connection associated with the member; and at least one conductive spring is attached to the member to make electrical contact with the means for making an electrical connection with the battery. The switch controls multiple functions of the flashlight including a strobe and a momentary mode. A pushbutton switch may control the multiple functions by multiple pushes on the switch.

  • Patent number: 7997756
    Abstract: Improvements in an emergency switch for an end cap flashlight that allows conducting power to the light source by applying side or rotational force on the end caps of the flashlight. 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.
