CX Series
Weather Sealed
Explosion Proof
Switches CX switches, as are the LSX/BX Series, are built especially for outdoor use in hazardous atmospheres.
These enclosures are constructed to withstand the pressure of an internal explosion.
O-ring seals make the enclosure weatherproof but are outside of required flame paths so explosion proof
requirements are maintained.
As factory assembled, all basic switches operate on clockwise and counterclockwise rotation. The
actuating mechanism can be field adjusted for CW or CCW operation only.
Analog output, 4 mA to 20 mA, is available.
Basic switches operate nearly simultaneously in multiple switch devices.
Shafts of devices without shaft restoring force can be rotated through 360°.
