An electric switch for correcting an input error is provided to correct the input error due to a difference between wiring patterns for each electrode by constantly maintaining parasitic factor of electrodes. An electric switch includes an electrode unit detecting an electric signal generated from contact of a human body through plural electrodes(301), a sensor unit receiving the electric signal from the electrode unit to convert the received signal into a digital signal, and a wiring unit connecting the electrode unit with the sensor unit. The wiring unit has a correcting element(303) for each electrodes. The correcting element is a capacitor or a resistor for constantly maintaining parasitic factors of the electrodes. The parasitic factor is capacitance or resist value.
