PURPOSE:To obtain a stable switching action free from effect of oxidation and contact pressure at a contact part by operating a capacitance coupling type switch employing a signal of a high frequency. CONSTITUTION:As a contact 9 of a switch SW is brought into contact with or close to a dielectric 10, an output pulse T1 of a divider 2 is inputted into an inverter 11. The output of the inverter 11 is inputted into a pulse conversion circuit 12 to correct a counting circuit 3 as single pulse. |
