The keypad includes a pcb (23), placed parallel with a sealing wall (3), and presenting, for each key, an emission antenna (27) surrounding a reception antenna (29). The reception antenna is connected to a conducting spring (31) resting on the opposite surface of the pcb. The spring opposite extremity is placed against the sealing wall. A display component is mounted on the same pcb surface without need of additional circuits.
