Abstract

PURPOSE: To simplify the pattern of a printed circuit plate and prevent piece contact of contacts dependent upon push-button operations, by causing a gum-formed material to bear a part of the constitution of the matrix circuit.
CONSTITUTION: The upper part of the casing of a desk computer is equipped with insulator holder 12 having hole 16 where push-botton 14 is inserted, and conductive gum-formed material 18 having plural elastic portruded parts 20 which are arranged vertically and horizontally is provided under holder 12; and when push-button 14 is depressed, contact 20a is brought into contact with contact 26 of printed circuit plate 24. Then, conductive gum-formed material 18 has insulator 22 which insulates and divides elastic protruded part 20 into blocks 18A, 18B... by functions such as a numeric and an operation symbol of the matrix, and for every block, conductive face 18a in the block is connected to contact part 28, which is provided on printed circuit plate 24, electrically by electric contact means 30.
