摘要
An electronic vacuum switch is described comprising a connector (6) having means (7) for the seal-closing of an outer body (1) having a cavity (60) within which a negative pressure sensor (8) exposed to the negative pressure of the environment under control and a circuit board (2) connected to the sensor (8) are housed. The negative pressure sensor is a ceramic pad integrated in a Wheatstone bridge (72) and the circuit board (2) is connected to said Wheatstone bridge (72) and comprises means (86) for the calibration of the Wheatstone bridge which are manually settable.
