ON/OFF delay circuit for consumer appliance circuit e.g. baking oven ventilation motor comprises RC timer system

摘要

Circuit for delayed ON and OFF of consumer appliance contains timer, incorporated in control circuit activated by closing of switch. Timer contains RC members for run-up and run-down delay, while timer output delays switch-on of consumer appliance. Breaking of switch starts run-down delay, during which consumer appliance is switched-off. Preferably current supply of electronic module takes place via different current paths during run-up delay period, operating period and in run-down delay period, so that run-up and run-down delay times are independent.
