US Patent:

7549766, Jun 23, 2009

Filed:

Aug 23, 2006

Appl. No.:

11/508383

Inventors:

Raymond L. Sharrah - Collegeville PA, US
Mark W. Snyder - Hockessin DE, US
Matthew B. Dalton - Elkins Park PA, US

Assignee:

Streamlight, Inc. - Eagleville PA

International Classification:

F21L 4/04

US Classification:

362205, 362191, 362197, 362285, 362427

Abstract:

A light and/or selector may comprise a selector rotatable and axially movable in a housing with a member rotatable therewith for indicating rotational position. A projection engages one or more recesses when the rotatable selector is proximate the housing and does not engage the recesses when the rotatable selector is distal the housing. A spring biases the rotatable selector towards the housing so that the rotatable selector must be pulled away from the housing against the bias of the spring to disengage the projection from the one or more recesses and to rotate.

Raymond L. Sharrah - Collegeville PA, US
Peter J. Ziegenfuss - Sellersville PA, US
Mark W. Snyder - Hockessin DE, US

Assignee:

Streamlight, Inc. - Eagleville PA

International Classification:

H01H 9/00

US Classification:

200 1B, 200 60, 200513

Abstract:

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.

Assignee:

Streamlight, Inc. - Eagleville PA

International Classification:

F21L 4/04

US Classification:

362205, 362202, 362206

Abstract:

An electrical switch comprises first and second switch elements including respective first and second electrically conductive flexible domes for selectively making electrical connections. The second switch element is disposed adjacent the first switch element with an electrical conductor therebetween. An actuator is movable for exerting force on the second switch element via a spring, and for exerting force on the first switch element via the spring and the second switch element. The second flexible dome may have an actuating force that is less than the actuating force of said first flexible dome.

Assignee:

Streamlight, Inc. - Eagleville PA

International Classification:

H01H 9/00

US Classification:

200 1B, 200 60, 200 5 R

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.

Assignee:

Streamlight, Inc. - Eagleville PA

International Classification:

H05B 37/02

US Classification:

200 60, 200 1 B, 2003022

Abstract:

An electrical switch comprises first and second switch elements each including a respective electrically conductive flexible dome for selectively making an electrical connection. The second switch element is adjacent the first switch element. An actuator is movable for exerting force on the first and second switch elements, wherein the flexible dome of the first switch element makes connection to a first electrical conductor when the actuator moves a first distance and the flexible dome of the second switch element makes the electrical connection to a second electrical conductor when the actuator moves a second distance in addition to the first distance.

Abstract:

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.
