Abstract:
Assembly for adjusting mobile elements of furniture, with a motor displaying a first and a second connection, a control circuit for controlling the motor, which is provided with at least a first push-button switch for controlling the motor, a power supply circuit with an operating voltage output, a mains connection located between a mains plug that can be connected to an alternating-current mains and the power supply circuit, a mains isolating relay displaying a relay switch and a control input controlling the relay switch, where the relay switch is located in the mains connection and is in OFF position when unexcited, and an auxiliary power source that is connected in parallel to the operating-voltage output, characterised in thatthe first push-button switch (5) forms an electric circuit with the motor (1) and the operating voltage output (10) and either the control input of the mains isolating relay (13) is connected in parallel to the motor (1) or a rectifier bridge (25), known as a Graetz bridge, which has four diodes, of which two first diodes have their cathodes interconnected in a positive node, while their anodes are each interconnected with the cathodes of the two second diodes in an alternating-current node and the cathodes of the two second diodes are interconnected in a positive node, and where one alternating-current node each is connected to the first and second connection of the motor and the positive and negative node are each connected to the control input of the mains isolating relay (13).
