ABSTRACT:
A stand for an electric iron incorporates an automatic time delay safety switch arrangement which reduces the chances of fires being started by an unattended iron and serves to save a substantial amount of electric energy by cutting off the current to the iron when it is left turned-on but unattended. The stand includes a hinged, spring biased platform of insulating material for supporting an electric iron during non-use periods. Placement of the iron on the platform causes the platform to pivot closing a normally open switch. Closure of the switch energizes a standard electrically energized time delay relay mounted on the platform. After lapse of a predetermined time period, the time delay relay actuates a manually resettable electric relay from a first condition allowing the electric iron to be energized from a power supply socket on the platform to a second latched condition whereby the iron is deenergized. Should the iron be removed from the platform before the lapse of the predetermined time period, the iron remains energized and the time delay automatically resets itself for the next placement of the iron on the platform. Actuation of the resettable relay to its second position also causes the time delay means to be automatically reset. However, a manual reset button on the resettable relay must be actuated to return the resettable relay to its first condition from the second condition to again energize the iron.
