摘要： A pressure sensor for detecting an electric arc in an electrical switchboard, the sensor being in an enclosed case containing a conical opening, the case being placed in the switchboard. A pressure switch in the sensor is attached to the interior of the case and is electrically connected to a circuit board for transmitting a signal when a contact in the pressure switch is closed. When a pressure wave created by the electric arc enters the case through the conical opening it forces a contact on the pressure switch to close thereby completing a circuit with the circuit board which transmits the signal to, for example, a central processor, to turn off the source of electricity thereby quenching the electric arc.

摘要： A hydraulic pressure switch apparatus includes a porous disc directly installed at a media entry port for dampening and filtration purposes. The porous disc includes a number of pores that are connected together and to the surface of the porous disc for allowing media to flow into a base fitting. The media exerts pressure on a piston associated with the base fitting, which in turn is capable of being absorbed by a compression spring. The compression spring transfers a required motion to a plunger associated with a micro switch in order to provide on/off switching capabilities. Electrical indications can then be transferred to a vehicle control unit utilizing a termination connector, based on particular user requirements. The porous disc can be utilized to dampen the pressure spikes and surges, which significantly prolong the life of the pressure switch apparatus in harsh applications.
摘要翻译：液压开关装置包括直接安装在介质入口处的多孔盘，用于阻尼和过滤目的。多孔盘包括多个孔，其连接在一起并连接到多孔盘的表面，以允许介质流入基座配件。介质对与基座配件相关联的活塞施加压力，其又能够被压缩弹簧吸收。压缩弹簧将所需的运动传递到与微动开关相关联的柱塞，以便提供开/关切换能力。然后可以基于特定的用户要求，使用终端连接器将电气指示传送到车辆控制单元。多孔盘可用于抑制压力尖峰和浪涌，这在苛刻的应用中显着延长了压力开关装置的使用寿命。

摘要： According to the present invention, a pressure-type contact switch comprising: a bourdon tube which expands and contracts depending on water pressure in a discharge conduit applied by a pressure pump; a first actuating lever connected to a free end of said bourdon tube and rotatably installed about a first rotation axis; a link connecting a free end of said bourdon tube and an end of said first actuating lever; a first semi-circle gear formed at the other end of said first actuating lever; a first link gear engaged with said first semi-circle gear and fitted to a central rotation axis to thereby cause said central rotation axis to rotate in normal and reverse directions; a rotation member fitted to said central rotation axis; a second actuating lever which is installed to said rotation member to be rotatable about a second rotation axis; an extension lever fitted to an end of said second actuating lever, wherein a rotation of said extension lever in normal and reverse directions is limited by a movable support rod and a stationary support rod; a second semi-circle gear formed at an end of a second actuating lever; a holder fitted to an upper end of a third rotation axis and having a rotation magnet inserted therein; a second link gear fitted to a lower end of said third rotation axis and engaged with said second semi-circle gear to thereby rotate said third rotation axis in normal and reversed directions depending on the rotation of said second semi-circle gear; a movable magnet arranged to be aligned with said rotation magnet in a straight line when said rotation magnet stops in its rotation by a first stopper, wherein the pressure pump turns off due to repulsive force between said rotation magnet and said movable magnet; and a stationary magnet arranged to be aligned with said rotation magnet in a straight line when said rotation magnet stops in its rotation by a second stopper, wherein the pressure pump turns on due to attractive force between said rotation magnet and said stationary magnet.
