<p>A method and an apparatus for preventing erroneous operation in a non-contact push-button switch. The method comprises impressing pulse power on a non-contact switch (1), and discriminating, in a discrimination circuit (4), between good or bad output signals from the switch to thereby selectively provide an operation signal to a driven circuit (5). In the event that an operation output is given from the switch, while the switch is actually in the OFF state, due to malfunction of electronic parts constituting the switch, no operation signal is output from the discrimination circuit (4) and accordingly the OFF state is maintained.</p> |
