Abstract: An automatic shut-off and indication device for an electric heating appliance is provided which includes: a sensor (2) for sensing usage of the appliance and for providing a usage-signal (US) indicating a non-usage of the appliance; a switch (10) for off-switching a heater (12) of the appliance in response to a switching signal (SS) derived from the usage-signal (US); a sensor (4) for sensing orientation of the appliance and for providing an orientation signal (OS) for indicating different orientations of the appliance; a selector (18) for activating an indicator (22) in response to the switching signal (SS), the indicator (22) signaling the off-switching of the heater (12); and an indication timer (8) for providing a time delay between off-switching the heater (12) and activating the indicator (22), which time delay is dependent on the orientation signal (OS). The shut-off of the heater (12) is signalled to the user by the indicator (22).

Abstract: A spark suppressor circuit (1) is provided for protection of an electrical switch (4) which in series with a load (2) is connected between a first supply voltage terminal (8) and a second supply voltage terminal (10), the load (2) and the electrical switch (4) being interconnected at a switch terminal (6).
