Abstract: A light source assembly comprises a dielectric body having an exterior surface and a light source mounted coaxially proximate an end of the dielectric body. A first electrical lead of the light source provides an electrical lead at an end of the dielectric body distal the solid state light source and a second electrical lead thereof provides an electrical lead at the periphery of the dielectric body. A resilient member improves electrical contact of the second electrical lead at the periphery.

Abstract: A switch as for a flashlight selectively connects, for example, a solid state light source and a battery in the flashlight in circuit for causing the solid state light source to produce light. The switch comprises a pushbutton and a metal contact having a periphery that selectively contacts a housing, and a spring. Pressing the pushbutton moves the pushbutton and the metal contact to contact the housing. The metal contact may include a feature for centering the metal contact with respect to the pushbutton and thus with respect to the housing end. The switch may be disposed in a tail cap attached to a flashlight housing.

Abstract: A flashlight comprises a housing having, for example, a tapered portion and a hole at a forward end thereof with a flexible/bendable extension including a solid state light source extending through the hole at the forward end thereof. A switch, preferably in a tail cap, selectively connects the solid state light source and at least one battery in the housing in circuit for causing the solid state light source to produce light. The flexible extension preferably makes electrical contact with the housing and/or preferably includes an insulating cover having an end retained in the housing.

Abstract: A switch as for a flashlight selectively connects, for example, a solid state light source and a battery in the flashlight in circuit for causing the solid state light source to produce light. The switch comprises a pushbutton and a metal contact having a circular periphery that selectively contacts a housing, and a spring. Pressing the pushbutton moves the pushbutton and the metal contact to contact the housing. The metal contact may be a ferrule having a cylindrical portion centered with respect to the housing end and a circular flange providing the circular periphery. The switch may be disposed in a tail cap attached to a flashlight housing at a cylindrical end thereof.
