<p>The present invention relates to a flow switch for turning on/off a contact point by relative location change of a movement magnet, a fixed magnet, and a lead switch. The present invention is able to accurately detect the flow of water within a pipe even though an angle which installs the flow switch is randomly selected and built. The present invention reduces manufacturing costs due to a simple structure which does not require a rotor body with a magnet and a hinge structure, and prevents chattering phenomenon on the flow switch which frequently occurred in a conventional flow switch.</p>
