Input device and input system

An input device, comprising:

• at least two fixed electrodes configured to be placed to overlap with specific line electrodes of a plurality of line electrodes;
• an operating member movable with respect to the at least two fixed electrodes,
• a plurality of contactors connected to the at least two fixed electrodes;
• and
• a movable electrode configured to move along with the operating member so as to come into contact with the contactors or out of contact with the contactors,
• the operating member being movable within a movable range including a plurality of click points,
• electrical states of the at least two fixed electrodes changing among a plurality of states in accordance with a movement of the operating member, and
• a divisor of an integer N not including 4, where the integer N is a total number of times that the electrical states of the at least two fixed electrodes change when the operating member moves from one to a next one of adjacent two click points of the plurality of click points, wherein
• either one of the movable electrode or the contactors is made of metal, and the rest of the movable electrode or the contactors is made of non-metal having electric conductivity.
