A guiding light system, comprising, in combination, an electric switch assembly, including a housing, a front plate on said housing, a toggle switch unit inside said housing having an outwardly protruding button through an opening in said front plate, said housing having three positions into which said button is selectively pivotable; a lowermost of said positions being an "off" position for electrical devices powered through said toggle switch unit, a middle one of said positions being an "on" position for said electrical devices, and an uppermost of said positions being an "off" position for said electrical devices while at the same time being a "blinking on" position for a remotely located signal lamp and a lamp on said button, said lowermost position being a "steady lighted on" position for said signal lamp and said button lamp, and said middle position being an "off" position for said signal lamp and said button lamp; said button being affixed on one end of a pivoted rocking lever, a contact plate affixed on an opposite end of said lever for selectively providing circuit closure means between a first pair of spaced-apart, stationary contacts of a power circuit to said electrical devices or providing circuit closure means between a second pair of spaced-apart, stationary contacts of a power circuit to said signal lamp; said button lamp being connected to a pair of contacts carried on said rocking lever, and which are selectively engagable either with a third or a fourth pair of stationary contacts, said third pair being in a power circuit including a step down transformer, and said fourth pair being in a power circuit including a blinker unit and a step down transformer; said first pair of contacts being engaged by said contact plate when said button is in said middle position, said second pair of contacts being engaged by said contact plate when said button is in said uppermost position, said third pair of contacts being engaged by said lever-carried contacts when said button is in said lowermost position, and said fourth pair of contacts being engaged by said lever-carried contacts when said button is also in said uppermost position.
