PURPOSE:To eliminate an electrical stepping in the resistance value at the start of a motor to secure a sure start, by connecting a correction resistance always to a resistance pattern. CONSTITUTION:A first slider 58 and a second slider 63 are permitted to slide and move from the start of non-contact. By the first slider 58, a resistance pattern 56 is connected to a first conductive pattern 57 to be short-circuited, and by the second slider 63, a second conductive pattern 61 is connected to a third conductive pattern 62 to be short-circuited. In this case, when the second conductive pattern 61 and the third conductive pattern 62 are permitted to come in contact with each other by the second slider 63 before the resistance pattern 56 and the first conductive pattern 57 are permitted to come in contact with each other by the first slider 58, then the patterns come in contact with a correction resistance 60 connected to the resistance pattern 56 always in parallel with each other, via the resistance pattern 56 through the second conductive pattern 61. Accordingly, a device starts certainly after it comes in contact with the resistance pattern 56 without being connected to the correction resistance only, thereby an electrical stepping is not generated. |
