Abstract: This input system includes an input device, an electrostatic sensor, a conduction sensor, a controller, and a determiner. When a movable contact of the input device is pressed, electrostatic capacitance between a first electrode and a second electrode changes, and when the movable contact of the input device is further pressed after the electrostatic capacitance changes, a third electrode and a fourth electrode are electrically conductive to each other. The conduction sensor detects the conduction between the third electrode and the fourth electrode. The controller switches the sensing operation of the electrostatic sensor from the OFF state to the ON state after the conduction sensor detects the conduction between the third electrode and the fourth electrode. In the ON state, the electrostatic sensor outputs a detected value related to the electrostatic capacitance between the first electrode and the second electrode.
