Electric illuminating lamp comprising on the one hand an electric bulb 5 carried by a first assembly called the bulb carrier 1 connected to a current source 13 via a switch, and on the other hand a parabolic reflector 8 carried by a second assembly called a parabola carrier 2, the two assemblies interacting so as to be able to be translationally displaced with respect to each other by rotating one of the assemblies with respect to the other, so that this relative displacement of the parabola carrier 2 causes, first, closure of the electric circuit and, second, regulation of the light beam, the said switch comprising at least one part 16, 160, 161 which can move between two positions, an inactive position in which the circuit is open and an active position in which the circuit is closed, characterised in that the movable piece is elastically stressed in the inactive position and comprises a projecting actuation part 20 intended in this position to be placed in a housing 21, 210 made in the parabola carrier assembly 2, and the passage from the inactive position to the active position is done by action of the parabola carrier 2 on the said movable piece. <IMAGE>
