Abstract

Electromechanical lifting apparatus, in particular for adjustments in beds, in which the connection and control of the driving motor are carried out pneumatically by means of a pressure transmitter arranged in a manual switch, the transmitter of which is connected to a switching device by means of a flexible pipe, characterized in that the volume of the pressure emitter can be increased and decreased from a central position, and that the switching device has a pressure transformer, which reacts to depression and overpressure, with two extreme positions in which it is in affective connection with a switch for left-hand running or with a switch for right-hand drive of the motor.
