General Instruction

CWA series magnetic blow-out micro switch is one of the auxiliary components for the high-voltage set of equipments. It is applied for signal collections of route, swing angle, limit position in various motive mechanisms. Meanwhile, the CWA could be assembled to auxiliary switch in high voltage mechanism, so as to control switch on & off and interlock of signals.

Meaning of the Symbol  


E.g.: model no. CWA1011 means CWA series, no wheel frame structure, 
with lid and plug.

Technical Parameters

Features of Structure
CWA series magnetic blow-out micro switch is assembled by plate case with internal components. The moving and stable contacts and connectors are all made of copper with silver plating. The insulated case is made of superior inflaming retarding material with high strength, good insulation property and heat-resistance, and the structure of the insulation plate ensures excellent dust-proof effects. It could be plug in from upwards or downwards for connection, NO and NC and poles are distinguished by colors for customers` convenient.

Route Parameters

 Note:X is the gap between guide rod/ guide wheel 
and the level of installed holes.

Installation and Operation
Please refer to switch draft for mounting dimension.
The CWA switch should be mounted to the target objects by fixing the two screw holes at two sides or in the middle position of the switch. The switch and the wheel should be operated in line and can`t be subject to yawing force. The operation should be controlled within allowed route range; otherwise, it will become deformed and not able to work normally.
