Abstract
A push button is composed of a head and a shaft which is pushed through a hole in a collar to operate a mechanism. It is returned by a spring and is prevented from coming out of the hole by a ring which fits into a groove at the end of the shaft farthest from the button. The shaft is envelloped by a membrane made of supple elastic material. The material is metal, preferably bronze or beryllium folded in concertina fashion. It provides a watertight seal and aids the return of the button. It also compensates for hydrostatic pressure is required. The membrane is welded or similarly joined to the button and to the collar using a laser. ADVANTAGE - Watertight, reliable, durable, aesthetic.
