Abstract

PURPOSE: To realize a circuit to operate a device only when two coins are charged, by using a coin switch of a simple type which changes over the contact upon charge of coin, thereby eliminating defects of complicated and easily broken mechanism.
CONSTITUTION: When a first coin is charged, a normally open contact B of a switch 1 is closed and a current flows into a first relay coil 2 to close contacts 3, 4. As the coin passes through and the switch 1 returns to normally closed contact A side, a current flows into a second relay coil 5 by way of A and closed contact 4, so that a normally closed relay contact 8 is opened, simultaneously closing contacts 6, 7. In this state, when a second coin is charged, the contact B of the switch 1 is closed, and a current flows into a third relay coil 9 through the contact 6, thereby closing contacts 10, 11. Even when the coin is completely passed through and the switch 1 returns to the contact A side, the current continues to flow into the coil 9 through contact 10, so that the contact 11 remains closed. Accordingly, a timer motor 13 passes current into a load circuit 12 according to a program, thereby permitting washing and drying operation.
