Abstract

An electrical control press button is coupled to one or more lamps which indicate the state of the controlled circuits and can be used as part of a keyboard. The button is sealed against water by a ring on the button. A rubber ring (23) is glued to the cap (2) of the press button and has a groove (24) around its periphery in which a sealing ring (25) of metal or plastics material is placed. This ensured sealing in the hole (26) between the button and front panel (19) on which the button is mounted. The rear face (28) of the ring acts as a shoulder which is arrested by a step plate (27) through which the return spring (16) passes. A transparent plug (30) protected by a film (30) is glued inside the button cover to complete the sealing.
