A low cost miniature illuminated pushbutton switch 10 for soldering to a circuit board ( 23 ), which avoids damage to an LED during such soldering to the board. The pushbutton assembly, which slides between outward and inward positions, includes a molded plastic frame ( 32 ), sheet metal pushbutton conductors ( 60, 62, 64 ) mounted on the frame, and an LED ( 36 ) having a bulb ( 74 ) lying forward of the frame and having leads ( 40, 42 ) joined to front ends of two of the pushbutton conductors. The pushbutton assembly also has a pushbutton depressing element ( 44 ) with a through passage ( 130 ) that surrounds the bulb and extends forward of the bulb, the pushbutton element having an inward end ( 132 ) that joins to the pushbutton frame through lugs ( 136 ). A pair of the sheet metal conductors ( 60, 62 ) have inward ends exposed to deflectable housing contact portions ( 96, 98 ), the sheet metal conductors have middle portions that extend through the frame, and the sheet metal conductors have outer ends forming crimp barrels ( 70, 72 ) that are crimped to the leads.
