Abstract

A remote control device for the joint or successive remote control of radio receivers, record players, tape recorders, television receivers and the like comprises a body having a plurality of control buttons for the items of equipment to be remotely controlled. The device further has a plurality of superimposed drop sheets each of which is associated with a specific item of equipment or function type. With the aid of a flap which is pivotally mounted on the body and a gripper provided on the flap, it is possible to raise the drop sheets, so that only that particular sheet required for the desired function type is present on the device. The drop sheets have openings through which the operating buttons can project. In the vicinity of these operating buttons a reference to a specific function is provided on each drop sheet.
