Abstract
A capacitance type sensor good in operability and less in erroneous operation is provided. Switches SW-SWare formed between a displacement electrodeand switch electrodes E-Ekept at a predetermined potential and grounded switch electrodes E-E. Switches SW-SWand SW-SWare connected to respective capacitance electrodes E-Ethat cooperate with the displacement electrodeto form capacitance elements. A decision circuit judges states of the switches SW-SW. When at least one of the switches SW-SWis off, an X-axial output is calculated based on the capacitance values of the capacitance elements Cand C, and a Y-axial output is calculated based on the capacitance values of the capacitance elements Cand C. When any of the switches SW-SWis on, a Z-axial output is calculated based on the sum of the capacitance values of the capacitance elements Cto C
