    • A pressure switch includes an external force transmission mechanism for separating a cover from a housing. The cover and the external force transmission mechanism defines a first pressure chamber, and the housing and the external force transmission mechanism defines a second pressure chamber. In the second pressure chamber, a movable piece having first and second movable members arranged opposite to each other and one or more fixed contacts are disposed. The first and second movable members are connected to each other via a flat spring. A contact is disposed on the second movable member and functions as a movable contact. The external force transmission mechanism applies an external force to the first movable member to displace the first movable member, and the second movable member is reversed at the operating point of the first movable member, so that the movable contact is brought into contact with the fixed contact.
    • 压力开关包括用于将盖与壳体分离的外力传递机构。 盖和外力传递机构限定第一压力室,壳体和外力传递机构限定第二压力室。 在第二压力室中设置有具有彼此相对布置的第一和第二可动构件和一个或多个固定触点的可动件。 第一和第二可移动部件经由板簧相互连接。 接触件设置在第二可动构件上并用作可动触点。 外力传递机构向第一可移动部件施加外力以使第一可移动部件移位,并且第二可动部件在第一可动部件的工作点处反转,使得可动触头与固定部件接触 联系。
