A plastic packaged straight slide coder includes a straight-shaped base plate (7), at least two signal output contact pieces (71) and at least one communal contact piece (72) are provided on the upper surface of the base plate (7), said signal output contact piece (71) is composed by conducting positions and insulating positions which are in alternative distribution and in line arrangement; a brush (5) with at least two metallic brush teeth is arranged relative to the signal output contact pieces (71) on the base plate (7), said at least two brush teeth are correspondingly in contact with said at least one signal output contact pieces (71) and at least one communal contact piece (72); a metallic terminal (6) is arranged on both ends of the base plate (7); the brush (5) can slide straight down the base plate (7) so that said brush teeth in turn can contact with different conducting positions and different insulating positions of said signal output contact pieces (71) and generate sequenced impulse signals. |
