Abstract
The invention discloses a programmable three-position switch. A screw is driven by a motor. A rotary encoding sensor for sensing rotation conditions of the screw is disposed on the screw and is connected with an encoder controller. The encoder controller is connected with a programmable controller which controls the motor to rotate. The rotary encoding controller outputs moving contact position signals to the programmable controller. The programmable controller further controls the motor to positively or reversely rotate and stop according to the moving contact position signals, so that the rotation states of the screw are controlled. The programmable three-position switch is reasonable in structure, convenient to operate, precise in operating position, and fine in operating performance.
