Hi- I have a Synchronome electrical 'master' clock - it is about 60 years old and has no electronics -just an electrical supply of about 6 volts. It has a pair of simple contacts which actuate every half minute which sets a gravity arm to drive the master clock pendulum together with several slave dials - the total current is about 0.3 amp for about one fifth of a second every half minute. The contacts on my clock are worn and I have refaced them, but I can see they will soon be useless - there is some slight sparking across them as the load is inductive due to the coils in the circuit - the steady DC voltage is about 6 volts. Can anyone help me with a circuit which would assist the contacts (I still wish to keep them) but perhaps allow them to just trigger a Darlington transistor BU941 or something similar. .....I know little about electronics so a circuit with values would be ideal....Parts for the clock are obsolete. I have tried searching the Forum but cannot see anything suitable. Anyway, many thanks if you can help me.
