<p>The device comprises levers (13,13') engaging the upturned storage container (5) and the support (9) for the nozzle (7) delivering the fluid to the dispensing element. The levers are spring-loaded (16,16') so that, without load, contact is made by elements (17,17') with the base (15). On removal of the container or the support electrical signals are fed to the electronic circuit (20) to power lights (18,19) on the front of the dispenser. The circuit includes a timing device to determine duration between removal of container and nozzle.</p> |
