accurate. The device is useful for household, safety purposes and even industrial applications. Examples
of their applications as switching devices are for heating, electronic heaters, radiators, radios, coffee
machines, various lighting arrangements e.g. for display windows, courtyards, stair cases, etc., or for
night switching of devices which are consuming large amount of electricity, such as laundry machines,
dryers or dish washers.
