LGW…A2P test button The LGW...A2P differential pressure switch is equipped with a test button. The test button permits a service friendly check of the safety function. If the test key is pressed while the pressure exists, the connection to the pressure connection G 1/4 is interrupted and the pressure under the diaphragm is released. The microswitch of the pressure switch changes the contact position from NO to NC. If the test button is released, the pressure below the diaphragms is built up again and the microswitch changes to its original position.
