I have tried searching the Forum but cannot see anything suitable. 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.Ĭan 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. 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 is no pendulum but there is a feather presentand another part which we have photographed. but he did not succeed in establishing a real production series or an. The last two digits are more difficultto read but the serial number appears to read 17633. 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. o master-clocks (clocks with a system of electrical contacts to enable the.
