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.

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 dustproof
effects. It could be plug in from upwards or downwards for connection,
NO and NC and poles are distinguished by colors for customers` convenient
