Control circuit wiring diagram
Type A Limit Position Switch 
Features: Actualizing Open and Close operations through AC
(alternating current) switching value, and output a group of
active position signals to indicate full-opened and full-closed.
Type B with 2 intermediate auxiliary position switches 
Features: Actualizing Open and Close operations through AC
(alternating current) switching value, and output a group of
passive contact signals corresponding to the full-opened and
full-closed positions
Structure: with 2 intermediate auxiliary position switches
Type C: Electrified Position 
Features: Controling the open operation through the switching value,
and continuous output the resistive signals that corresponding
to the open position
Structure: with 1KΩ potentiometer
Type D: with potentiometer and intermediate position switch
Features: Controling the open operation through the
switching value, and continuous output the resistive signals
that corresponding to the open position，simultaneous
output a group of passive contact signals corresponding to the
full-opened and full-closed positions
