CWL Limit Switch

Features
♦ Double-circuit type of limit switch. is widely used
♦ With strong aluminum case outer shell
♦ High mechanical streanth
♦ Structure prevending oil , water and pressure
♦ Indicating plate with setting position is installed in it, so it is easy to maintain
♦ Various of actuators is taken convenience for using
♦ Built-it contact stand has double-spring, so it has long mechanical life

NOTES:
1.Inductive load has a power factor of 0.4 min.(AC) and a time constant of 7 msec, max.(DC)
2.Lamp load has an inrush current of 10 minutes the steady-state current, while motor load has an inrush current of 6 times the steady-state current.
