<p>A coin selector is switched from standby to operative mode when a coin 6 fed into the selector engages and moves a rocker arm 1 carrying a mobile permanent magnet (3) to actuate a fixed magnetic relay (4) close to that magnet. The displacement of the rocker arm pulls the magnet, varying the action of the magnet's magnetic field on the relay. The relay is connected to a power supply circuit for the sensor, which connects when a coin is introduced. <IMAGE></p> |
