Use the 1N4148 for the signal paths as a 1N4001 diode is a rectifier diode and is meant to operate at low AC frequencies. Diodes that can handle large current and voltages are known as power diodes. At the moment the coil circuit is opened, the current that was flowing through the coil now goes through the diode. This gives it a lower emission coefficient "eta" (sometimes written "n"). Its name follows the JEDEC nomenclature. Only 11 left in stock - order soon. (1N914 is an identical device to the 1N4148) They will do exactly the same job in switch and lamp matrixes for pinball BUT the 4004/7 is a much tougher device and will withstand the shaking and bashing a lot better than the more fragile glass bodied diode. 1N4007 diode has a cathode (-) and anode (+).
