摘要:
A switch comprising a first contact on a support surface, a switch housing sealingly secured to the support surface around the first contact to form a hermetically sealed chamber about the first contact, and a second contact movable in the chamber towards and away from the first contact, wherein the support surface is provided on a support having two or more protrusions protruding from the support surface and received in apertures formed in the switch housing to locate the switch housing relative to the first contact.

A membrane switch can attach an elastically deformable dome to a board in a reliable manner such that the dome is not detached even if a fixing sheet is made thinner and smaller and therefore has a smaller footprint. This switch has: a dome (110) that is formed projecting toward the surface and that is dented opposite toward the back surface by elastic deformation; and a flexible fixing sheet (120) that has a back surface of an adhesive face pasted to the entire face of the surface of the dome (110). The fixing sheet (120) fixes the dome (110) in a predetermined position of a board (4) by means of a stretching part (122) which stretches radially outer to the dome (110), from an outer rim (112) of the dome (110), in a direction virtually orthogonal to a direction in which the dome (110) projects. A plurality of slits (130) formed in the fixing sheet (120) at predetermined intervals along the outer rim (112) of the dome (110), prevent a stretching part (122) of the fixing sheet (120), from joining with a dome covering part (121) which is a portion above the dome (110) that continues in the radial direction of the dome (110).

A modular operating switch assembly comprises a housing defining a plurality of switch operating cells. Each of the operating cells has guide walls, a switch actuating member in sliding contact with the guide walls, and a switch contact carrier configured to be selectively equipped with contact pairs such that each of the contact pairs is associated with at least one said switch actuating member. Each switch actuating member is operable to be selectively connected to a key cap associated with a single switch operating cell, or with a key cap associated with a plurality of adjacent switch operating cells.

An intermediate displacement board (120) composed of a metal plate is arranged on a printed circuit board (110) having electrode patterns (E1-E7) and then a strain generative body (130) composed of silicon rubber is arranged on top thereof. Then, the arrangement is fixed to the printed circuit board (110) with attachments (140). Depressing a displacement portion (133) causes a connecting portion (132) to be deflected and an electrode (F0) to be brought into contact with the electrodes (E1, E2) to make them conductive, thereby allowing the pushbutton switch to be turned ON. Depressing further the displacement portion (133) causes an elastic deformation portion (134) to be elastically deformed and crushed and the intermediate displacement board (120) to be pushed downward. The capacitance of capacitors (C3-C7), which are constituted by the electrodes (E3-E7) and the intermediate displacement board (120), are varied according to the depression of the intermediate displacement board (120). By detecting the variation in capacitance, it becomes possible to detect three-dimensional components of an applied force.

An electrical switch mounted on a circuit board and providing tactile feedback includes a domed tripper (18) and an elastomeric actuator (16) with a rod having an upper operating end (78) that can be depressed to snap down the tripper and close the switch. The actuator has a lower sealing lip (62) extending in a 360° circle around the tripper and lying against the circuit board upper face, to form a sealed cavity (56) containing the tripper. The 360° sealing lip of the actuator is pressed down against the circuit board by a cap (14) that has a side wall (26) with a lower edge (38) pressing down against the sealing lip. The cap has feet (42) extending down through holes in the circuit board, the feet having latches (48) that hold the cap in place.

The present invention provides an assembling system of rubber cones of computer keyboards and an assembling method for the same. The assembling system of rubber cones of computer keyboards of the present invention comprises an assembly housing, a moldboard stage, a rocking apparatus, and a rotating apparatus. The assembly housing has an operational space. The moldboard stage has a plurality of moldboards, and is arranged above the operational space of the assembly housing. Each moldboard corresponds to a keyboard to be assembled, and has a plurality of recesses corresponding to key switches of the keyboard on the surface thereof. The rocking apparatus and the rotating apparatus join with the moldboard stage at two sides thereof to provide required rocking and rotating forces for the moldboard. Thereby, the present invention can partly automate the originally wholly-artificial assembling method, increase the assembly efficiency, and reduce the cost of manpower.
