Abstract

PURPOSE:To perform the start and stop of a load by a timer only during the self- holding of a self-holding circuit, by providing a contact of the timer in series with a load and its self-holding contact. CONSTITUTION:An automatic closed type switch 10 to stop the operation of a load 5 and a failure detection switch 11 to open the load by detecting through the detection of failure of the load are connected in series with a self-holding type circuit including a contact 4 of a self-holding relay 3 in addition to a main power switch. When the main power switch 1 is closed and the switches 10, 11 are closed, if an automatic opened type switch 2 is momentarily activated, the relay 3 is self-held via the contact 4. Thus, when the a-side of a timer contact 7 is allowed to contact, the load 5 is energized, and when the b-side of the timer contact 7 is closed, the load 5 is not energized and a timer motor 6 is energized, allowing to energize the load after a prescribed time.
