･ According to the construction by which a Bourdon tube move directly functions the microswitch, the number of constituent parts is small and excellent durability is demonstrated.
･ Furthermore, pressure range extends extensively from low pressure to high pressure:0.1 MPa to 70 MPa, complying with extensive ranges.
･ Moreover, this pressure switch has been developed mainly for thermal power stations, equipped with a large wiring space, assuring easy maintenance work.
