  • Contactless snap-action photoelectric switch
    Patent number: 4196348
    Abstract: A contactless switch which comprises a paired light-emitting diode and photoelectric transistor and a shutter means for temporarily blocking light passing from the diode to the transistor. A method for the production of this switch is also described. The above diode and transistor are mounted on terminal members stamped in a metal strip, which terminal members are connected by webs as molded but trimmed off from each other in assembling. The terminal members are embedded at least partially in a switch base made of plastic material and bent to bring said diode and transistor in confronting relation. The snap action means is associated with an actuator.
