A guide holder device of a keyboard switch (2) includes an upper projection (3) and a pair of lower projections (4,4') for receiving a guide arm (7) into a recess (5) formed between them. The guide holder device is integrally formed with the keyboard switch so as to reduce the assembling process of the guide holder. A pair of guide stems (8,9) are prepared apart at both sides of the keyboard switch located beneath a key top (6), and holds the both ends of the guide arm.
