Abstract

PURPOSE: To achieve a highly reliable interlocking operation of a gas water heater and a ventilating fan by use of an economical circuitry, that is, with no use of complicated semiconductor circuits or switching mechanisms.
CONSTITUTION: A switch 2 for starting and stopping operation of a motor 1 for driving a ventilating fan is designed to close either one of contacts K1 or K2 and also to close another contact K3 with movement of a lock plate 10 through a distance l when either of "strong current" of "weak current" push buttons 11, 12 depressed. Through the contact K3, current is supplied to the first relay 4 from a circuit 6p for feeding current to motor 1, and a relay contact R1 for the second relay 5 is connected in series to a relay contact R2. This relay 5 is connected, by a plug 7p, to a socket C of a switch means 8 which makes a closed circuit through detection of gas or temperature during use of a gas water heater G.
