  • Patent number: 4809254
    Abstract: It is conventional in relation to automatic retraction mechanisms to position a switch that advances a slide-out compartment in and out either on the front surface of the compartment or behind it at a fixed point inside the device where it can be activated by the compartment, which the operator applies pressure over a short distance to for that purpose. The object of the invention is accordingly to provide a reliable, cost-effective, and user-friendly solution.This object is attained with absolutely already existing components in that the retraction mechanism travels a short distance when pressed, accordingly rotating the rotor component of the motor (1) through the intermediary of the drive mechanism, a rack (3) and pinion (2) and if necessary a belt (4) for example, and causing it to generate electromagnetic force. The resulting pulse is processed in the form of a signal by a simple processing circuit (17) and supplied in the form of a switching command to controls, usually a microcomputer (18).
