| 20090026058 | TRIGGER MECHANISM - A trigger mechanism for an electric power tool, comprises a spring-loaded trigger movable between an foremost position and an rearmost position, an adjuster for adjusting the rearmost position, an electrical switch arranged for closing by the trigger while the trigger is in an intermediate position, and a variable resistor arranged for operation by the trigger while the trigger is in an intermediate position to provide a resistance having a value dependent upon the position of the trigger. A locking device is included for locking the trigger near the rearmost position, and which is movable in opposite directions and arranged to lock the trigger near the rearmost position when the locking device is moved in either one of opposite directions. | 01-29-2009 |
| 20090057122 | Trigger switch - Disclosed a trigger switch having an insulative enclosure, a movable contact element and a sliding control device slidably mounted to the insulative enclosure. The insulative enclosure includes a case and a cover. The case has plural terminal subassemblies made of conductive metal members disposed therein. The case has an opening over which the cover is mounted. A fixed contact mounted on one of the terminal subassemblies in the case. The movable contact element has a movable contact mounted at one end of the movable contact element and located opposite to the fixed contact. The movable contact element is swingably supported on another terminal subassembly. A trigger is mounted at one end of the sliding control device. An auxiliary brush is interposed in the movable contact element. A support member is provided with an opening portion in which the auxiliary brush is engaged such that the brush is swingably supported. | 03-05-2009 |
| 20090139849 | Trigger Switch - Disclosed a trigger switch including fixed contacts forming main contacts double in series and functioning as a switch for supplying a motor with power and slide plate parts connected to the fixed contacts; and movable contacts provided in an actuator interlocking with an operation part and auxiliary contacts sliding on the slide plate parts. Drawing the operation part causes the actuator to move forward making the movable contact come into electric contact with the fixed contact to supply the motor with power, simultaneously making the auxiliary contact bridge over the slide plate parts to achieve electric contact to make no potential in the contact between the movable contact and the fixed contact. Releasing the operation part make the movable contact separate from the fixed contact, simultaneously making the auxiliary contact bridging over the slide plate parts cause a break of the contact with the slide plate part. | 06-04-2009 |
| 20100025216 | TRIGGER SWITCH - A trigger switch includes a first locating element, an elastic second locating element, and a pressing element slidably attached to the bezel. The pressing element is restricted by the first locating element to a first position of the bezel to prevent the trigger portion from contacting the trigger element. The second locating element restricts the pressing element to a second position of the bezel to further prevent the trigger portion from contacting the trigger element. The trigger portion contacts and applies a force to the trigger element to trigger the trigger element when the pressing element overcomes elastic forces of the second locating element. | 02-04-2010 |
| 20100187085 | TRIGGER SWITCH - In a trigger switch having a normal and reverse switching lever configured to switch the direction of rotation of a motor, a case is formed with a speed control unit storage chamber for storing a speed control unit, a revolving shaft storage chamber for storing a revolving shaft of the switching lever and a contact strip member storage chamber with continuing from the revolving shaft storage chamber through a shielding member therebetween for storing contact strip member of the switching lever, the revolving shaft storage chamber is formed with a revolving shaft engaging hole configured to allow the revolving shaft to be inserted in an engaged state on an upper portion thereof on the side of the trigger lever, and a waterproof device for covering at least a gap between the switching lever and the revolving shaft engaging hole is provided to prevent entry of water therein. | 07-29-2010 |
| 20110089012 | ELECTRONIC DEVICE - 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. | 04-21-2011 |
| 20130098746 | KEY AND ELECTRONIC DEVICE USING THE SAME - An electronic device includes a housing, and a key fixed to the housing. The key comprises a key cap fixed to the housing, a trigger component protruded from a surface of the key cap. The trigger component defines at least one recessed portion, the at least one recessed portion extends from one end of the trigger component away from the key cap to the other end of the trigger component from which the trigger component extends. | 04-25-2013 |
| 20130140167 | TRIGGER SWITCH - Embodiments of the invention provide a trigger switch in which a trigger is pulled into a housing so as to operate a contact mechanism, thereby driving a motor of an electric drill. The inside of the housing is divided into a first region including a circuit in which a main electric current for driving the motor flows, and a second region including the contact mechanism of a signal circuit which controls a rotation of the motor. An air vent is disposed on an outer circumferential surface of the first region of the housing. The trigger switch can reduce operational failure due to dust and the like without making the structure thereof complicated. | 06-06-2013 |
| 20130213785 | TRIGGER MECHANISM FOR HAND HELD DEVICES - A trigger mechanism includes soft stops and an associated method activates 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. | 08-22-2013 |
