The circuit includes a central unit which, on receiving a signal, proving that the boot has been opened, due to a switch being activated, delivers a command to start a timed operation of the lamp. The timed supply circuit (10) for a lamp (14) operates when a switch (13) is activated by the opening of the boot. It includes a first circuit (20) for detection of the closure of this switch, and a second part (21) for timed provision of current to the lamp circuit. A central processing unit (11) is connected so that when it receives a signal indicating that the boot is open it provides a control signal (19) acting on a switch (16) in order to start a timed operation of the lamp. The timing circuit is isolated from the detection circuit by a diode (15). |
