![]() The contact opens/closes depending on the contact type.Īs soon as the flow is interrupted, the paddle returns to its original position and the reed switch contact opens/closes depending on the contact type. The magnet (2) changes its position in relation to the reed switch contact (3). The paddle system is moved once it comes into contact with the flow which is to be monitored. A second, magnet (4) with opposite polarity is used to create a reset force. A reed contact (3) is positioned outside the flow above this magnet. The flow switch consists of a paddle system (1) which has a permanent magnet (2) located at its upper end. The switch typically operates through the use of a paddle which gets displaced due to the force of fluid moving past it. ![]() Flow Switch is a mechanical switch that is switched on or off in response to the flow or non-flow of a fluid such as air or water.
