A luminous element holding structure for an illuminated key switch arrangement includes a key having a transparent window, a housing for containing switch operating members, the housing having a recess, a flange and a pair of catches, a holding plate provided with through holes each for receiving the lower portion of the housing, a base plate, a switch element having pairs of switch contacts, and pairs of fixed electrodes each for conducting current to a luminous element, and a luminous element holder disposed in the recess of the housing. The lead wires of a luminous element are inserted forcibly in through holes formed in a pair of conductive members of the luminous element holder so that the luminous element is held firmly by the luminous element holder. The luminous element holder is set in the recess of the housing and the key is combined with the housing so that the transparent window is located opposite to the luminous element held on the luminous element holder. The housing is placed on the holding plate so that the lower portion thereof is received in the through hole and the flange is seated on the surface of the holding plate. The holding plate is combined with the base plate so that the conductive members of the luminous element holder are pressed, respectively against the pair of fixed electrodes to connect the luminous element eletrically to the pair of fixed electrodes.
