Pressure Switches

Pressure Switches

Cole-Parmer has a wide range of switches from which to choose. We carry standard switches as well as industrial switches. Industrial switches will have a very durable case to protect the electronics of the unit and even will have explosion cases for many applications, such as in oil and gas exploration and extraction. When not in a very dangerous industrial process, most switches will have a stainless steel case to protect the unit from mild acids and slightly caustic applications. All switches are used for their output to control pumps, switches, PLCs, or just send a signal to a panel meter to control processes or signal need for attention. If you have questions about a differential pressure switch contact a Cole-Parmer Technical Expert.
