Abstract
A capacitance type sensor good in operability and less in erroneous operation is provided. Switches SWto SWare formed between a displacement electrodeand switch electrodes Eto Ekept at a predetermined potential and grounded switch electrodes Eto E. Switches SWto SWare connected to respective capacitance electrodes Eto Ethat cooperate with the displacement electrodeto form capacitance elements. A decision circuit judges states of the switches SWto SW. When at least one of the switches SWto SWis off, periodic signals are input only to the capacitance electrodes Eto Ecorresponding to X- and Y-axial directions. When any of the switches SWto SWis on, a periodic signal is input only to the capacitance electrode Ecorresponding to a Z-axial direction.
