Abstract
The switching system is designed for a plan printing machine having a fluorescent tube printer and a developer. The developer is fitted with at least a heating resistance and a thermostat. The reproduction support of the machine is driven by a motor. (M) The machine has a development liquid supply system which is fitted with a liq. flow control and a stop start switch (MA) for machine control. The electrical circuits of the machine are connected to a voltage supply source. The switching system uses a multicontact relay and a controlled invertor (1) connected to the coil of the relay. The invertor is also connected to one of the voltage supply source terminals when the machine is stopped. Closure of the stop start switch connected to the relays coil and to the other terminal of the voltage supply, actuates the closure of the relay contacts. The fint, relay contacts ensures the supply is maintained to the relay.
