摘要:
An electrical 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 pushbutton must be moved over a distance substantially greater than an actuation distance of the flexible dome to apply sufficient force to cause the shorter leg to contact the second conductor and the dome to contact the third conductor. A spring between the pushbutton and the flexible dome couples force to the flexible dome.

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.

A portable light or device may comprise: a light source or operative element; a switch for controlling energization of the light source or operative element; and a housing supporting the light or operative element and the switch. The housing has a compartment having a relatively larger transverse dimension in one region for receiving a battery having a corresponding larger transverse dimension and has a relatively smaller transverse dimension at least at one end thereof for receiving a battery having a corresponding smaller transverse dimension. At least one electrical contact in the compartment is movable for making electrical connection to batteries having a relatively shorter length and a relatively longer length.

An electrical circuit structure for a light may comprise: at least first and second circuit portions disposed in different planes; the first circuit portion having a shape corresponding to the shape of a mounting surface adjacent to which it is adapted to be mounted, the first circuit portion having an opening therein for receiving a light source; a light source mounted in the opening of the first circuit portion for receiving electrical energy; and a switch mounted to the second circuit portion for selectively applying electrical energy for selectively energizing the light source.

A portable light may comprise: a light body having a light source module disposable in an external opening having a given cross-sectional shape and size for receiving the light source module therein. The light source module may comprise: a light source, a reflector and a heat sink thermally coupled to the light source. The light source module may include a circuit board between the reflector and the heat sink for supporting the light source and being thermally coupled to the heat sink
