  • Ribs l6 and shoulder 17 are centrically disposed about the longitudinal axis of housing 11 and serve to divide the internal housing cavity into four chambers utilized for mounting diodes and into a central star-shaped or substantially cross-shaped chamber into which a plug member snap-lockingly is inserted.
  • a contact spring 18, sometimes also referred to as spring contact, is provided on top of each shoulder 17, the contact spring 18 having a horizontal supporting plate 19, a vertical guide flap or tab 20 which serves to hold the spring in the housing, and a downwardly extending contact arm 21.
