The invention provides an arrangement comprising a substrate (12) and an electrical component (14) which comprises a base (20) made of insulating material and connection terminals (40), each of which is connected to a connection pad (18) of the substrate (12) by means of a spot (60) of solder paste, characterized in that it includes a block (62) which is interposed between the substrate (12) and the base (20) of the component, which block is located substantially on the axis (A-A) of application of the force (F) for actuating the component, in order to avoid deformation of the base (20), and consists of a spot of solder paste soldered to an associated conducting pad (64) on the substrate (12). The present invention also provides an application to the mounting of a push-button electrical switch.
