An automatic pump comprises a case; an impeller, a motor, a connection unit, a flux switch unit, and a lid switch unit(160). The lid switch unit comprises a switch body(161) forming a fixing groove on an inner middle portion; a switch cover(163) installing plural fixing protrusions on a portion corresponding to the fixing grove; a base plate(165) forming patterns on vertical ends portions by being fixed by the fixing protrusion of the switch cover while forming a concave unit; a lid switch(167) soldering-fixed on both ends of the pattern corresponding to the concave unit of the base plate; and plural wires soldering-fixed to the pattern.
