Patent ID: 7427724

Claim:
An electrical switch having a tactile effect, which includes a lower casing having a lower face designed to rest on the upper face of a printed-circuit board, the lower casing having an internal cavity and at least two fixed electrical contact elements lying in a bottom of the cavity, each contact being connected to a connection tab that projects to the outside of the casing for the electrical connection of the fixed contact element to a conducting track on the printed-circuit board, a trip member of domed general shape which is housed in the cavity and is elastically deformable from a stable rest state under the action of an actuating member, wherein a lower part of the actuating member acts on the trip member along a direction approximately perpendicular to the bottom of the cavity, and at least one light source carried by a support plate which lies above the open upper face of the cavity, which straddles the actuating member and which includes terminals for electrical connection of the light source to a power supply circuit for the light source, wherein: the electrical connection terminals of the light source extend to the outside of the casing and vertically along vertical lateral faces of the casing.
