Control system for glue gun

An apparatus for delivering a melted material comprising:

• a body having a nozzle and an internal cavity for receiving a stick of meltable material;
• a heat source mounted in said body adjacent said nozzle;
• a pusher derivably received within said internal cavity for forcing said stick toward said nozzle, said pusher derivable to and from a reload position to a fully advanced position;
• a load position magnet on a first end of said pusher;
• a reverse position magnet on a second end of said pusher;
• and
• a sensor stationarily mounted in said body to sense said load position magnet when said pusher is in said reload position and to sense said reverse position magnet when said pusher is in said fully advanced position.

A method of delivering a melted material comprising the steps of:

• providing a dispenser with a cavity, a nozzle, an electrically driven pusher, a heat source adjacent the nozzle, and a control circuit having a switch for supplying power to the heat source and to the pusher;
• inserting a stick of meltable material in said cavity;
• closing said switch to heat the heat source and to advance the pusher to force the stick of meltable material into contact with said heat source to create melted material that flows out said nozzle;
• then
• once a quantity of said melted material has been dispensed, opening said switch;
• and
• removing power to said heat source, causing the control circuit to automatically retract said pusher a distance to relieve pressure on said stick to eliminate unwanted drips.
