Below is a list of Level Switches manufacturers from South Plainfield, New Jersey. Level switches, also sometimes called level control switches, are measuring utilities that indicate material levels in storage enclosures or transmission equipment; in some cases they can be used both for level measurement and level control. A level switch indicates these levels by means of an electrical switching action. Some of these devices could also be classified as level sensors or level indicators; those terms are restricted to systems that measure levels but do not control them.
