Abstract
A cooking appliance with touch pad controls is protected against inadvertent turning of a cooking facility such as a hob ring to full power by a spillage on an UP pad (increase temperature). A control circuit turns the facility off if the UP pad signals that it is touched for longer than say 5-7 seconds. Similarly a warning can be given if a DOWN pad remains touched too long, to prevent inadvertent turning off of a facility.
