Electrical timer-switch

A timer-switch comprising an enclosing casing;

• an electrical switch supported therein having two electric switch contacts and a movable electricity conducting element for electrically connecting and disconnecting said switch contacts;
• a clock motor also supported within the casing;
• mechanical connecting means from the clock motor to said movable conducting element to operate it at a predetermined interval and thereby electrically connect and disconnect said switch contacts;
• a first prong and a second prong supported by the casing and constituting a pair of conventionally disposed prongs projecting from the casing for entry in a conventional wall electrical outlet;
• a third prong supported by the casing and projecting in an unconventional position outside of said pair of prongs;
• a wire connecting said third prong to one of said switch contacts and another wire connecting the other switch contact to said first prong, whereby closure of said switch by said movable element electrically connects said third prong to said first prong.
