ABSTRACT:
A circuit board for electrical instrument control having patterns to which is applied a high voltage. In preventing the high voltage when appearing across the patterns from producing a faulty circuit operation, or damaging circuit elements by leakage, there is no need particularly for separating the high voltage patterns to another circuit board, or adding a circuit for protection against the high voltage, when providing a circuit board deprived of the bad influence of the high voltage patterns.
