The gas pressure switch C6097A is used to detect the pressure of city gas, natural gas, LP gas or air etc. When the gas pressure changes, the diaphragm of the pressure receiving part detects it and operates the (SPDT) switch to ON/OFF control of the external electrical circuit.
These switches are widely used to detect the upper limit or lower limit pressure of gas or air to be supplied to a gas burner, or to detect the clogging of the interlock filter of a burner blower
