Patent number: 8872052Abstract: This novel jumper features an integrated mechanical switch that allows resetting the CMOS memory of computer motherboards just by actuating a reset button on the jumper, instead of moving a prior-art jumper back and forth over the CMOS-reset block. The disclosed jumper can also be adapted for use as temporary button for powering on, restarting and resetting motherboards when tested alone; in this case the jumper just needs to be inserted over the corresponding pair of pins on the front-panel header of the motherboard. This jumper is also applicable to other electric or electronic devices where operating the jumper's integrated switch is more convenient or safer than moving prior-art jumpers or manually shorting up pins on printed circuit boards.Type: GrantFiled: April 23, 2008Date of Patent: October 28, 2014Inventor: Juan Zak

Patent number: 8507818Abstract: Disclosed is a push switch device. Since a push button is pressed to relatively rotate first and second pressing members in opposite directions and a push direction conversion unit converts the relative rotation of the first and second pressing members into a push movement in a switching direction, a pressing projection of the first pressing member can accurately vertically press an apex of a movable terminal. Therefore, a sense of click when the movable terminal is resiliently deformed and recovered can be maintained well, and a slide friction generated between the movable terminal and the pressing projection of the first pressing member can be minimized, preventing decrease in sense of operation and reduction in lifespan of parts due to the friction. In addition, an operation sense of the push button can be improved because straightness of the push button can be improved and there is no additional repulsion, except the repulsion by the resilient deformation of the movable terminal.Type: GrantFiled: March 10, 2011Date of Patent: August 13, 2013Assignee: Magma Co., Ltd.Inventor: Young-Kap Kwak

Patent number: 7994447Abstract: Upward urging force by operation force of a tact switch and restoring force of a rubber body are applied to an operation body via a pressing body. Then, pressing operation of a push button section causes the operation body to press down the rear ends of left and right sections of the pressing body. This follows that, with both contact sections in contact with a step section functioning as the support points, an operation section on the front end of the pressing body is pressed up to turn on the tact switch. In this process, when the push button section is pressed, the center of rotation of the operation body is changed depending on which portion of the push button section is pressed, causing the distance between a pressed portion of the operation body and the center of the rotation are almost equal independent of which portion is pressed. As a result, the load to operate the push button section is substantially equalized independent of which portion of the operation body is pressed.Type: GrantFiled: August 21, 2007Date of Patent: August 9, 2011Assignee: Idec CorporationInventor: Takayuki Sakai

The rotor 13 has first and second operating-element-side protrusions 19 and 20 with respect to the body-side protrusions 9 and 10 which have sloped surface and steps and are arcuate. The rotor 13 has a rod 18. As the rotor 1 is operated, the rod 18 is protruded from a through-hole 8, thus performing a switching operation. When the switch device 1 is operated, the force of operation of the operating knob 3 is improved, being the sum of a frictional force attributing to the slip between the sloped surfaces of the protrusions 9 and 10 and the sloped surfaces of the protrusions 19 and 20.Type: GrantFiled: August 7, 1997Date of Patent: November 16, 1999Assignee: Kabushiki Kaisha Tokai Rika Denki SeisakushoInventor: Hiroshi Ueno

Patent number: 5860514Abstract: An actuator mechanism for alternate action switching devices having at least two states includes a housing structure and an actuator member slidably engaged therewith. In order to move the switching device between states, the actuator member has a contoured surface that moves along and remains in constant sliding engagement with a correspondingly contoured surface on the housing. A biasing member urges the actuator surface into the housing surface throughout operation. This provides noiseless operation of the switching device.Type: GrantFiled: November 8, 1996Date of Patent: January 19, 1999Assignee: UT Automotive Dearborn, Inc.Inventors: Glen H. Beattie, Dale R.

Patent number: 5626223Abstract: The present invention includes a cam-assisted switch. A keycap or button is provided with three or more cam contact points. A cam member is provided with an associated number of outwardly extending fingers corresponding to each cam contact point on the keycap. Each finger has a flat top surface, side surfaces and a slope surface extending from the top surface to a side surface. A base is provided with cam finger stops and a dome support point. A dome is carried on the dome support to bias the cam in one direction. As the keycap is depressed, the contact points each engage a sloped surface on one of the respective cam fingers. As the keycap is further depressed, the displacement of each keycap contact point is the same thus eliminating any wobble. When the operator releases the keycap, the dome biases the cam in the opposite direction returning the keycap to its original position.Type: GrantFiled: July 1, 1996Date of Patent: May 6, 1997Assignee: Packard Hughes Interconnect CompanyInventor: James S.

Patent number: 5586645Abstract: A quiet smooth acting push button switch, which permits partial actuation without a change of state, including a body, a cover and a contact cup having one or more tabs, the cup rotatibly mounted on the cover. A plunger, actuator and a ratchet with radially expanding helical camming ramps are mounted in the body, which incrementally rotate the contact cup and tabs upon successive actuations of the switch. Two terminals mounted on the cover are interruptably in contact with the tabs as the tabs are rotated during switch operation. The actuator may be a pawl, bail or a resilient portion of the plunger and has at least one hook for engaging a helical camming surface of the ratchet and rotatibly driving the rachet in response to a depression and release of the plunger.Type: GrantFiled: November 20, 1995Date of Patent: December 24, 1996Inventor: Stephen Bartok

Patent number: 5558211Abstract: A protective switch having an actuation side. The protective switch includes a base having walls, a pivot shaft connected to the walls of the base, and a switching rocker pivotal on the pivot shaft to be pivotally seated on the base. The switching rocker includes two lever arms for switching the protective switch on and off. A housing is placed on the base and protectively surrounds the switching rocker. A housing cover is located on the actuation side of the protective switch and protectively covers the switching rocker. The housing cover includes an opening therethrough. A plurality of hinges are each disposed on a respective lever arm of the switching rocker. An actuation attachment extends through the opening of the housing cover and is modularly connected to the switching rocker by the hinges for pivoting the switching rocker.Type: GrantFiled: March 15, 1995Date of Patent: September 24, 1996Assignee: Ellenberger & Poensgen GmbHInventors: Konrad Heydner, Oswald Onderka

Patent number: 5226529Abstract: A pushbutton switch which permits partial actuation without a change of state, including a body, a cover and a contact cup having a plurality of tabs, the cup rotatably mounted on the cover. A plunger and ratchet mechanism mounted in the body incrementally rotate the contact cup and tabs upon successive actuations of the switch. A first terminal mounted on the cover is interruptibly in contact with one of the tabs as they are rotated by operation of the ratchet mechanism, while a second terminal mounted on the cover maintains electrical contact with the contact cup. A plurality of camming ramps formed in the cover are in intermittent communication with the tabs, first lifting them above a planar portion of the first terminal, then permitting one of them to come to rest on the planar portion of the terminal completing an electrical circuit between the first and second terminals. In another embodiment, a third terminal is mounted on the cover in a coplanar spaced apart relationship with the first terminal.Type: GrantFiled: April 19, 1991Date of Patent: July 13, 1993Assignee: Judco Manufacturing, Inc.Inventor: Joseph F.
