| A circuit pattern on a circuit board, as used in telecommunications systems and other electrical apparatus, often has contact positions for switches, such as pushbutton switches, and for other purposes. The normal copper circuit pattern is covered at the contact positions to give improved contact conditions. Carbon ink has been proposed by obtaining the necessary high level of alignment of carbon ink with the copper pattern at contact positions is difficult as such contact positions have very close members. The invention proposes contact positions having closely spaced inter-digital contact members, in which the circuit pattern extends to and stops at the peripheral region of a contact position, the contact members being of carbon ink and overlapping conductors of the circuit pattern at the peripheral region. | ||||||

| PROBLEM TO BE SOLVED: To suppress the radiation of radiant noise generated between wiring patterns formed on the circuit pattern to outside the circuit board and a keyboard device by forming a ground pattern between wiring patterns. SOLUTION: This device consists of wiring patterns 31 led out of solder lands 8 and 9, output terminal parts formed at one-end sides of the wiring patterns 31, an integrated circuit for control which is connected to the solder lands 8 and 9, and the ground pattern 30 for holding an earth potential. Then the ground pattern is formed between the wiring patterns 31. Consequently, the wiring patterns 31 led out of the solder lands 8 and 9 have capacity connections with the ground pattern 30 arranged between the wiring patterns 31, and high frequency noise mixed with signals flowing through the wiring patterns 31 is made to flow to the ground pattern 30 by the capacitive connections. Consequently, the high-frequency noise mixed with the signals can be reduced. COPYRIGHT: (C)1997,JPO | ||||||

| Disclosed is a data entry keyboard which has a multitude of depressible keys which are selectively depressed for the entry of predetermined data. In the keyboard, an insulating member is sandwiched between a first substrate having stationary electrodes and a flexible second substrate having movable electrodes. The stationary and movable electrodes face one another through apertures formed in the insulating member. Upper and lower marginal surface portions of the insulating member, including the respective peripheral edges of the apertures, are kept parallel to the first and second substrates corresponding thereto by a plurality of protuberances on the substrates so that voids with a predetermined width are left between the marginal surface portions and the individual substrates. The movable electrodes of the second substrate are electrically fixed, in the form of a cantilever each, to the extreme end portions of branch conductor strips which diverge from a main conductor strip at right angles thereto. When one of the keys is depressed, the second substrate is deformed to narrow the corresponding void, thus bringing the corresponding movable and stationary electrodes into contact with each other. | ||||||
