a) Retractable control especially for programmers intended for domestic electrical appliances. b) Characterised essentially in that it consists of an internal supporting body 1 on which an intermediate ring 5 can move telescopically, whilst, in its turn, the control 12 can move on this ring, also telescopically, there being provision for the internal supporting body, starting from this cylindrical collar, to include a disc-shaped flank 29, and on the periphery of this flank, which gives rise to the formation of an elastic arm 16 terminated at its free end by a latching tooth 17, whilst the control 12 includes a small hollow protuberance 18 open towards the front face of this control, in which is situated a small pusher 21, this pusher bearing, in the course of its movement inwards in its housing, causing the lateral deformation of this elastic arm and the exiting of this retaining tooth from the orifice of the protuberance 18. c) The invention relates to a retractable control especially for programmers intended for domestic electrical appliances. <IMAGE>
