A circuit board system comprises a circuit board having a base part (101) and at least one changeable part (102) furnished with at least one electrical component (103) such as a light emitting diode. The base part comprises an aperture for receiving the changeable part so that a perpendicular of the changeable part is parallel with a perpendicular of the base part. The aperture is shaped to allow the position of the changeable part to be changed with respect to the base part when the changeable part is in the aperture, and edges of the aperture and the changeable part have mutually cooperative connection portions (105, 106) which allow the changeable part to be introduced on the aperture when the changeable part is in a first position and which limit freedom of the changeable part to get away from the aperture when the changeable part is in a second position. |
