Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a keyboard switch that has wide applicability as an operation input switch means for various electrical and electronic devices.
The present invention relates to a keyboard switch that can be operated not only by directly applying force such as a finger ring, but also by magnetic force.

As shown in FIG. 1, the keyboard switch includes a flexible base member 2 on which a plurality of required fixed contact patterns 1 are formed, and a hard base member 2, which is provided on the base member 2 and is linked with each of the fixed contact patterns 1. a flexible switch sheet 6 having movable contact patterns 5 disposed on insulating spacers 4 arranged to form switch operation spaces 113 and performing switch operations separately in correspondence with each of the fixed contact patterns 1; , and a bonding layer 7 made of an adhesive or the like between these constituent members. When operating such a keyboard switch, a human finger or the like is used to open or close the switch by directly pressing the top of the switch. In cases where it is necessary to operate the switch alone, the conventional mid-board switch structure as described above cannot handle the situation. The present invention provides nine new and modified life-board switches constructed to solve the above problems, which will be described in more detail according to the illustrated embodiments:
In FIG. 2, 10 is a pace member, 11 is an insulating spacer disposed on the pace member 10, 12 is a switch sheet, 13 and 14 are contact pattern sets, and 15 is a pace member at a corresponding portion of the contact pattern 14. According to the structure of such a board switch, which is provided on the outer surface of the switch sheet 10 with adhesive IIIK and is a good magnetic member, the switch sheet 12 can be connected by applying force from the top of the switch sheet 12 with a finger or the like.
) Contact pattern 15, 14d [In addition to contacting and operating as a switch as before, by bringing a magnetic member close to the upper part of the switch sheet 12, the contact pattern 14 is attracted with the pace member 10 by magnetic force. The mutual O-contact patterns 13, 14 are in contact and can operate as a switch. Furthermore, in the ζO embodiment, if a member having magnetism like a magnet is provided in place of the magnetic member 15,
It is also possible to obtain the same switching effect as described above not only by a member having magnetism, but also by having a magnetic member not having magnetism in close proximity. It is understood that the same effect can be obtained by providing the magnetic member t or the magnetic member 15 on the switch sheet 12 in the opposite manner to the above.

ζIf the member 15 is configured to be a permanent magnet type magnetic member, the magnetic repulsion caused by the magnetic member of the same polarity as the magnetic member of the same polarity will cause both contact patterns to 15.140 Selective switching operation is achieved @ 5th Ill both of the members are made of magnetic material and both contact patterns 13 and 14 are magnetized in the unclosed S cover in the normal part and are different from each other. Polar magnetic members 16, 17 are connected to the switch sheet 12. Another embodiment is shown in which the pace member 100 is provided separately. In this case, the magnetic member 16 is provided separately.
It is also possible to bring a magnetic member of the same polarity as 17 close to either side to perform the switching operation.

Even if there is a deviation K, according to this embodiment, even if a hard member such as glass is disposed on the surface, it is possible to operate the switch by magnetic force. 41 is effective in places where . In addition, as a means for forming the magnetic member, the magnetic member 15, or the different polarity magnetic member 16m17, these members may be used. Either form 4 into a single piece and join them individually to the above-mentioned predetermined portions, or 9 must be placed on a film member with as much flexibility as possible during bending. In addition, it is possible to use a material that has been joined in advance in a similar arrangement, or it is possible to use a film member such as the upper part, which is formed as appropriate using a printing method, etc. It is permissible to take optimal measures that take into account the needs of these assemblers.The keyboard switch of the present invention not only can be operated with a finger ring as in the past, but also can be operated without directly touching the surface of the switch. This makes it possible to further expand the field of application of this type of medium-port switch. It should be noted that the base member in the above embodiment is made of the same material as the switch sheet on the upper part of the base member and is folded in half. It is formed in a central shape so that the operator can perceive that the snap action or switch operation has been completed during operation, and various symbols, markings, or inputs are provided so that the switch selection operation can be specified. It also falls within the scope 11 of the present invention to configure a decorative board with information display capacity, ie, an operation display sheet, to provide a life board switch 0*WJK.
