Abstract

A multi-mode portable illumination device includes a switch structure featuring a substantially planar member and a mechanical switch which requires a relatively small amount of force and a short stroke distance to actuate. The mechanical switch is attached to a member which contains circuit(s) adding additional functionality to the multi-mode portable illumination device. The member has conductive springs attached to either end that are used to complete the electrical circuit with the battery and the lamp, while their compressive force is absorbed by a housing protecting the switch structure. A conductive strip is used to improve the conductivity of the circuit in a metal multi-mode portable illumination device which has been provided with an electrically resistive protective coating.

First claim

What is claimed is:

1. A flashlight, comprising:
a barrel having a head end and a tail cap end;
a power source held within the barrel;
an LED light source for emitting light from the head;
a mechanical switch;
a circuit that electrically connects the power source, the LED light source, and the mechanical switch; and
electronics which produce a plurality of functions of operation for the LED light source in response to a plurality of different actuation actions of the mechanical switch by a user of the flashlight.
