The electrical switching device (1) has a housing (3) which can be fastened on a support (2), an actuator (8) having a pressing surface and illuminating means for visualization of the pressing surface. A disc-like cover plate (6) which has a contact surface (6b) for a piezoelectric switching element (12) provided in the housing is arranged on the front of the housing (3). Said switching element is arranged in such a way that an electrical signal is generated on pressing the actuator (8) in contact with the cover plate (6). According to the invention, the cover plate (6) is at least partly transparent and is provided, on its underside, facing the interior of the housing (3), with several light emitting diodes (16) distributed regularly over a circle and intended for radiating light out of the cover plate (6).
