Modular electric light switch assembly

A modular switch assembly comprising:

• a switch component receptacle holder adapted to be mounted in a wall receptacle;
• a female component permanently attached in said receptacle holder including, a pair of spaced apart electrical contact elements, each of said contact elements having a metallic housing, first conductor means in said housing adapted to receive in contact therewith current-carrying electrical wires and comprising a resilient metal plate bent back on itself to form a pair of spaced surfaces, said plate having an entry passage into the space between the spaced surfaces for frictionally receiving the current-carrying electrical wires, and second conductor means in said housing for electrically connecting said resilient metallic plate to said metallic housing when resiliently spaced or spread apart by the current-carrying electrical wires, and a cover on said female component having a pair of spaced prong-receiving openings, each of which is in alignment with one of said electrical contact elements;
• and
• a male component insertable into said receptacle holder including a pair of protruding electrically conductive prongs extending through said prong-receiving openings in said cover into electrical series contact with said electrical contact elements in said female component.
