Abstract
A limit switch control device comprises a shaft, a sensor, an upper limit reed switch, a lower limit reed switch and a drive element that cooperate with a control circuit. The sensor is combined on the shaft which is driven by the drive element, which is provided with an upper limit witch and a lower limit switch, so that when the sensor detects the upper limit and the lower limit reed switches, the upper and the lower limit switches will be triggered to power off the drive element.
