Quoted from BuckNaked:Just don't hold the flipper up for a long period of time because it won't drop to the low voltage hold circuit.
This statement is not true for DE games.
DE flipper acts on time based. After defined time (30-40 msec) the voltage drops to low level.
The function of EOS is only to detect the upper position of the flipper, and in case of raptor coil backfire, the voltage moves back to higher level for short time in order to keep the flipper at high position.
