Abstract:
A panel switch and a method of manufacturing the same are provided. The panel switch includes insulating films and a base layer having a stationary contact. Each insulating film includes an adhesive layer, and an apex portion of a moving contact adhered to the adhesive layer. The insulating films are aligned and adhered on top of each other and the adhered insulating films are aligned and adhered to the base layer such that the locations of the moving contacts of the respective insulating films align with the stationary contact of the base layer. The method includes applying an adhesive layer to an insulating film; adhering a moving contact onto the adhesive layer; aligning the moving contact with a stationary contact of a base member and adhering the insulating film to the base member; and cutting and removing an excess portion from the insulating film with a laser.
Abstract:
To fully control the local heating of a chassis, an electronic apparatus comprises a push-button switch (10) including a first contacting part (11a) and a second contacting part (11b) conductive to the first contacting part provided on a substrate (11) and inside a flexible clicking part (13a) of an insulating layer (13) covering the substrate. When the clicking part is pushed, the conduction state between the first contacting point and the second contacting point is switched between connected and disconnected. The insulating layer (13) has a heat conducting layer (14) extending along the substrate (11).

Abstract:
Hand-held placement dispenser element (6) and automated dispenser elements (18) are provided for placement of items such as metal domes or the like onto a placement position (21), such as right-side-up or upside-down, perhaps by allowing only a single item or predetermined number of items to eject from a dispenser element at a time. A dispenser element may include a trigger (7) allowing for non-complication in use. A dispenser element could accept a cartridge (1), such as a slotted cartridge (3). A dispenser element and cartridge may be interchangeable. Once a cartridge is empty, it may be desirable to remove the empty cartridge and replace it with a full one.
Abstract:
The invention provides a two-step push-on switch in which first and second switches are sequentially turned ON as a result of a depressing operation, and a movable contact plate configured by a metal plate spring is fixed by an adhesive tape onto a circuit board without deteriorating the operation characteristics of the movable contact plate. A spacer 20 is placed around the movable contact plate 1 on the circuit board 8, and a continuous or discontinuous tape-sticking face 21 which is lower in level than the top of a center plate portion 3 and higher than a peripheral plate portion 2 is formed by the spacer 20 around the movable contact plate 1, thereby preventing the adhesive tape 9 or 19 from sticking to the peripheral plate portion 2. In the adhesive tape 19, nonadhesive portions 27, 27 are formed in places opposing to parts of the peripheral plate portion 2 of the movable contact plate 1 excluding at least the connecting portions with the connecting plate portions 4, 4, respectively. Even when the adhesive tape 19 makes contact with the peripheral plate portion 2 during the process of turning ON the first switch, the adhesive tape 19 is prevented from sticking to the peripheral plate portion 2.
Abstract:
The invention provides a movable contact for a two-step push-on switch which can realize an excellent sense and a long life period while decreasing the width, even on a flat stationary-contact forming surface of a printed circuit board, a flexible printed circuit board or the like, and also a two-step push-on switch. A movable contact has: a rectangular annular peripheral plate portion 2; an oval center plate portion 3 which is upward inflatingly curved; and a pair of connecting plate portions 4, 4 which connect an inner edge of the peripheral plate portion 2 to an outer edge of said center plate portion 3 on a center line X which is parallel to long side portions 2a, 2a of said peripheral plate portion 2. The movable contact is disposed on a flat stationary-contact forming surface of a printed circuit board, a flexible printed circuit board, or the like, and an adhesive tape 9 for fixing the movable contact is bonded from a side of the upper face, thereby configuring a push-on switch.
Abstract:
A pushbutton switch (1) includes a fixed contact portion (3) provided on a substrate (2) and an elastically deformable movable contact portion (4) provided in opposition to a surface of the fixed contact portion, the movable contact portion being configured as a dome-like portion forming a greater gap relative to the surface of the fixed contact portion at a center portion of the surface than at a peripheral portion of the surface. The fixed contact portion (3) includes, at a center portion on the surface thereof, a surface-devoid portion (5) forming a contact edge (30) in cooperation with the surface, and the movable contact portion (4) includes a projection (6) projecting toward the surface-devoid portion of the fixed contact portion. When a press force is applied to the movable contact portion (4), the movable contact portion is elastically deformed against resilience thereof toward the contact edge (30) to come into contact with the edge or an area adjacent thereto. When the press force is released, the movable contact portion (4) is elastically restored to move its projection (6) away from the contact edge (30) or the adjacent area.
Abstract:
The sheet with movable contacts comprises a first sheet formed by an insulating film, the first sheet having an adhesive surface formed by applying an adhesive to a lower surface of the first sheet, a plurality of domed, metallic, movable contacts whose upper surfaces are covered with and affixed to the adhesive surface of the first sheet, and a second sheet formed by an insulating film, the second sheet being affixed to the lower surface of the first sheet and having a plurality of receptacle holes for receiving the movable contacts therein, with an adhesive being applied to a lower surface of the second sheet, wherein the second sheet has connecting slots formed therein for connecting adjacent such receptacle holes with each other.
