Abstract
An operation switch includes: a capacitance sensor that generates three or more detection signals in response to approach or contact of an object to respective three or more electrodes; a determination circuit that determines whether or not the object is a living body based on one or more detection signals selected from the three or more detection signals, the one or more detection signals excluding a detection signal having a maximum intensity among the three or more detection signals; and a controller that, when the object is determined to be a living body, generates an operation signal for operating a predetermined device.
