Coin machine counter ejection control circuit - has transistor driven relay changing voltage polarity with contacts connected to two rectifiers via capacitors

摘要

At a fairground where the vehicles are powered by AC via conducting strips in the floor the coin machine which controls power supply utilises a coin counter to establish electrical contact. The counter is ejected when the power is switched to DC. A fairground vehicle carries contacts (1-4) which connect to power conducting strips in the floor. These contacts are connected via capacitors (C2-C5) to two bridge rectifier circuits in parallel between two conductors (11, 12). These power the coin machine counter ejector circuit via relay contacts (a1, a2).
