Power scissor jack, especially for automobiles, has signal amplifier circuit which transfers amplified signals to motor control circuit to turn motor clockwise or anticlockwise or to stop it so lifter is raised, lowered or stopped

摘要

The device has a signal generator (1), a corresponding signal reception circuit, a signal amplifier circuit and a control circuit for the lifting motor. The signals received by the receiver circuit are amplified by the signal amplifier circuit which transfers the amplified signals to the motor control circuit to turn motor clockwise or anticlockwise or to stop it so that the lifter is raised, lowered or stopped.
