ABSTRACT:
A switch device having a housing connectible to a side wall of a flow conduit, a cup element dangling at the end of a string in the conduit is adapted under a predetermined pressure of fluid flowing through the pipe to draw a magnet connected in the housing at the other end of the string against the bias of a spring away from a reed switch so as to move the contacts of the latter from one condition to another.
