A water-preventing grommet for a pull chain switch has a cylindrical body with an abutting end and an inclined distal end, a recess defined in the abutting end, a downward passage defined in the inclined distal end to communicate with the recess. The inclined distal end has a flat inclined face, a top extending portion and a bottom guiding portion. The downward passage in the inclined distal end extends to the bottom guiding portion. When the grommet is placed in at a right position, the top extending portion shades the downward passage from rain drops. Meanwhile, the downward passage also eliminates water up-flow to keep water away from the pull chain switch.
