一、 Use：
JX cut signal is applied to signaling element wicket Station shear pin when cut, so that shear pin signal device is turned on the alarm.
二、 Structural features：
This signal has normally closed and normally open two.
Normally closed:
This element uses the latest technology with its shell brittle materials, the internal use of printed circuits, sealed with epoxy resin poured through sealed, so good insulation and moisture resistant, suitable for wet environments turbine particular, when used in power plants, directly to each signal is connected in series, and means coupling the signal alar.
Normally open type:
From the shell, jack, spring and micro switch composed, normal operation, the switch is in a free state, when the shear pin is cut off, while this element is cut off after the jack under the spring action against the switch the switch normally open contact closure, normally closed contacts disconnect, issue shear pin breakage signal.

Contact the form of a conversion.
四、 the use Notes
The elements can be inserted directly into shear pin hole, the weld wire connectors can be put into operation (see Wiring Refer to Figure).
