A light guided keyboard system essentially comprised of a light emission circuit and a guide control circuit built in the keyboard; an EL lamp or other light emitting device being connected to the light emission circuit; and guide software such as spelling guide or typing method guide, application software control interface and driver being included in the computer software unit to guide typing of spelling, characters, applications, web pages, game software, and pre-schooling education programs in faster and easier operation of the keyboard.

When the assembly is complete, the protrusion 2e of the leaf spring 2b abuts against the bottom wall surface 3g which is an inner bottom surface of the cover member 3 and the leaf spring 2b is bent. Since the protrusion is pushed against the cover member 3, the leaf spring 2b generates force of repulsion which pushes the frame member 2f toward the opposite direction of the cover member 3. In addition, since the leaf springs 2b are aligned straightly between three bosses 3b, the leaf spring 2b pushes the push button 2 toward the switch board 1 almost in parallel. In other words, if the push button 2 is held in the cover member 3, without further components, the push button 2 is pushed against the switch board 1 and there will not be a possibility of a wobble.

A portable electronic device includes a housing including at a hole, an elastic structure including at an actuator wedged in the hole of the housing, and a circuit board installed below the housing. A metal dome is located corresponding to the actuator for outputting a key signal when pressed.

A button assembly is described. The button assembly includes a light emitting device that emits light. The button assembly further includes a lens cap that protects the light emitting device from being damaged. The lens cap has a top surface, a first cap side, a second cap side, a third cap side, and a fourth cap side. The second cap side connected to the first cap side, the third cap side connected to the second cap side, and the fourth cap side connected to the first cap side and the third cap side to form a plane. A first perpendicular distance between the plane and a first point on the top surface is different than a second perpendicular distance between the plane and a second point on the top surface. Additionally, a system for increasing life of a pixel is described.

An improved water sealing side key system for use in electronic device 24, such as but not limited to a mobile phone, and which provides for the construction of the seal assembly 21 as a rigid frame 29 and an elastomeric sealing material that allows for both a compressive and circumferential (perimeter) seal 28 as well as the overall non-binding movement of a side key 20 within the seal and the ability to closely control the thickness, tolerance spacing and tactile feel of the side key 20.

A waterproof keyboard includes a generally flat key panel supporting keytops thereon. Membranes support thereon key contacts and connecting circuits for the contacts, and are supported by a generally flat support base, corresponding in shape to the key panel. Between the membranes and the key panel, a waterproof layer is supported by the support base for sealing the membranes in cooperation with the base. The waterproof layer, made of a sheet of flexible synthetic resin, is pressed with an elongate elastic member against the edge portion of the support base. The key panel is fixed to the support base to cause the waterproof layer and support base to seal the membranes, which will surely be protected from dust and moisture.

A base button 4 wuth a button depressing surface and a shaft portion, and a shaft supporting portion for slidably supporting the shaft portion of the button base 4 are provided. A switch base installable on a print wiring board, a contact rubber providing a conductive portion at a position facing the print wiring board , and a light emitting portion provided on the print wiring board are also included. The shaft portion is lowered by depressing the button depressing surface of the button base 4 and the conductive portion of the contact rubber is lowered until the conductive portion contacts an electrical contact on the print wiring board. Thus, an electrical contact function is exerted and the light emitting portion emits light, when the conducts portion comes into contact with the electrical contact.

A protective cover includes a cover body and a pressing body integrally mounted to the cover body. The cover body has an accommodating cavity recessed from a surface of the cover body and an accommodating hole defined through the base wall of the accommodating cavity. The pressing body is mounted to the cover body and includes a pressing portion and a resisting post. The pressing portion is configured for being received within the accommodating cavity and exposed from the accommodating hole. The resisting post protruding from a surface of the pressing portion away from the cover body corresponding to the switch. There also discloses a key assembly using the protective cover and a portable electronic device using the key assembly.

An electronic module that is activated by the touch of a button for sending a wireless signal to a remote receiver. The module has a housing with an upper portion that is secured in relation to a vehicle. A lower portion of the housing has mating apertures and openings provided therein. A set of staking posts extends from an upper face of one or more buttons. The staking posts have a leading end that is registrable with the mating apertures that are provided in the lower portion of the housing. A set of actuating posts also extends from the upper face of the button. Those posts extend within at least some of the openings that are defined in the lower portion of the housing. Optionally, an array of light pipes is in optical communication with a set of switches. One of the switches can be closed following contact by a leading end of one of the posts when a button is depressed. A printed circuit board is positioned in operative communication with one or more of the buttons so that upon touching a button, a circuit in the circuit board is closed by one of the switches. A signal is then sent wirelessly to a remote receiver.

A keyswitch includes a cap, internal and external sleeves, a resilient arm, a base having a pillar, and an elastic member abutting against the internal sleeve and the base. The internal sleeve jackets the pillar, abuts against the cap and has a first outer annular surface with a transverse slot. The external sleeve jackets the internal sleeve and has a protruding block movably inserted into the transverse slot for guiding the external sleeve to rotate and a second outer annular surface having concave and convex portions and an arc-shaped bar. When the resilient arm abuts against a second position on the convex portion and the cap presses the external sleeve, the resilient arm crosses the arc-shaped bar. When the resilient arm abuts against a first position on the convex portion and the cap presses the external sleeve, the resilient arm does not need to cross the arc-shaped bar.

Influence of an impact on a hard base or deformation of the hard base is alleviated on a circuit board.

A push-button switch cover member has a hard base 1 and a keypad 2, the hard base 1 is made of a hard resin with a through hole 4 for a key top, and the keypad 2 is made of a silicone rubber film. The keypad 2 thinly covers the entire back surface of the hard base 1 and is exposed through an internal periphery of the through hole 4 of the hard base 1 to the front surface side of the hard base 1. The back side of the keypad 2 located in an inside region of the through hole 4 is provided with a press projection 6a for press of a contact part.

An elastic member for a pushbutton switch with which a soft tactile sensation can be gained when the pushbutton is pressed down is provided. The elastic member for a pushbutton switch is provided with a base portion, a connection portion which extends from the base portion, a pressing portion which is supported above the base portion by the connection portion, and a protrusion which protrudes downward from the pressing portion. The inside of the protrusion is hollow.
