Publication number: 20110089012Abstract: An electronic device includes a power switch, an elastic force member adjacent to the power switch, a triggering member fixed on the elastic force member to trigger the power switch, and an elastic reposition member. The triggering member is capable of sliding between a first position and a second position relative to the power switch. The elastic reposition member provides elastic force to move the triggering member from the first position to the second position. In the first position, the triggering member faces the power switch and can be pressed to trigger the power switch. In the second position, the triggering member is away from the power switch.Type: ApplicationFiled: December 31, 2009Publication date: April 21, 2011Applicants: HONG FU JIN PRECISION INDUSTRY (ShenZhen) CO., LTD., HON HAI PRECISION INDUSTRY CO., LTD.Inventors: ZI-MING TANG, WEI-JUN WANG

Patent number: 7820931Abstract: A device includes a trigger arrangement activating a function of the device. The trigger arrangement includes a trigger mechanism movable between a first position and a second position. The device also includes a feedback mechanism exerting a force biasing the trigger mechanism to the first position. The feedback mechanism produces a tactile feedback response when the trigger mechanism is moved from the first position.Type: GrantFiled: July 25, 2007Date of Patent: October 26, 2010Assignee: Symbol Technologies, Inc.Inventors: Roland Lee, Robert Spano

Publication number: 20100258631Abstract: A trigger mechanism with soft stops and associated method for activating a switch in a device or apparatus. The trigger mechanism includes a trigger receptacle, a trigger disposed in the trigger receptacle and movable between an un-actuated and an actuated position by a user depressing the trigger, and a soft stop comprised of at least one projection positioned to engage a resilient elastomeric insert. Moving the trigger from the un-actuated to actuated position compresses the elastomeric insert with the projection and activates the switch to provide a tactile sensation of the switch activation to the user. The switch may be an electric switch disposed in a hand held device, such as a barcode scanner in some embodiments.Type: ApplicationFiled: April 9, 2009Publication date: October 14, 2010Applicant: Metrologic Instruments, Inc.Inventors: Gregory Mark Rueblinger, Kai Wang, Daniel J.

Patent number: 7786397Abstract: Method and device are provided where a barrier is formed at or around the trigger of a device with a rest area for the index finger so that the finger can remain (extended) off the trigger when the device is not in use. Position and/or size of the rest area is adjustable to, for example, accommodate index fingers of various sizes. Adjustment of the position of the rest area can be achieved by means of a screw which slides a resting piece to a selected correct location, or by means of inserts that may be indexed to a selected length. Device can be a nailer, and the barrier is configured to accommodate a depth gage of the nailer.Type: GrantFiled: September 20, 2007Date of Patent: August 31, 2010Assignee: Makita U.S.A., Inc.Inventor: Roderick Dick

Patent number: 7754989Abstract: An electrical switch has a fixed contact and a moving contact arranged for movement between an ON position in contact with the fixed contact and an OFF position out of contact with the fixed contact, and an operating member for operating the moving contact. A spring co-acts between the operating member and the moving contact and resiliently biases the moving contact towards each of the ON and OFF positions through an over-centre action of the spring. An end piece is fitted at each end of the spring, which has a formation, for example, a groove, for pure rotary engagement with a part, for example, a pin, movable with the operating member or moving contact for imparting resilient action upon the operating member or the moving contact.Type: GrantFiled: December 19, 2007Date of Patent: July 13, 2010Assignee: Defond Components LimitedInventor: Kin Yu Wong

Patent number: 7723632Abstract: An electrical switch has two fixed contacts and a moving contact, a spring urging the moving contact towards contacting the fixed contacts, and an actuating mechanism for moving the moving contact away from the fixed contacts against urging by the spring and, alternatively, allowing the moving contact to contact the fixed contacts under the action of the spring. The actuating mechanism has an engaging member for engaging and retaining the moving contact and includes a spring acting on the engaging member for separating the moving contact from the fixed contacts through an instant spring-release action. One of the engaging member and the contacts is configured such that the moving contact will be engaged and moved by the engaging member out of contact with one of the fixed contacts earlier than with the other fixed contact.Type: GrantFiled: April 30, 2007Date of Patent: May 25, 2010Assignee: Defond Components LimitedInventor: Kin Yu Wong

Patent number: 7705260Abstract: A switch assembly provides a pressing plate on a pivot contact lever to minimize heat generation at the point between the pivot contact lever and the contact point by providing an additional parallel connection contact plate which is in parallel connection to the pivot contact lever. The switch assembly provides convex contact portions on the internal output ports of the forward/reverse switch mechanism. A supplementary elastic metal plate to the pivot contact lever is provided to solve the problem of loose contact at the pivot connection site where the pivot contact lever and the support unit meet, and provides a supplementary contact unit to the movable contact device at the forward/reverse switch mechanism.Type: GrantFiled: April 12, 2006Date of Patent: April 27, 2010Inventor: Xinsheng Xu
