摘要： A pressure switch comprising an external force transmission mechanism separating a cover and a housing, a first pressure chamber sectioned by the cover and the external force transmission mechanism, and a second pressure chamber sectioned by the housing and the external force transmission mechanism. The second pressure chamber is provided with a movable piece having first and second movable portions located oppositely, and one or more fixed contacts. The first and second movable portions are coupled through a leaf spring. The second movable portion is provided with a contact functioning as a movable contact. When the external force transmission mechanism applies an external force to the first movable portion, the first movable portion is displaced, the second movable portion is reversed at the action point of the first movable portion, and thus the movable contact comes into contact with the fixed contact.

摘要： A pressure switch in accordance with the present invention includes an external force transmission mechanism for separating a cover and a housing from each other. A chamber defined by the above-mentioned cover and the above-mentioned external force transmission mechanism serves as a first pressure chamber, and a chamber defined by the above-mentioned housing and the above-mentioned external force transmission mechanism serves as 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 above-mentioned 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 above-mentioned movable contact and the above-mentioned fixed contact are brought into contact with each other.
