Abstract: A waterproof switch assembly having a rigid casing with a first opening, a compressible elastomeric body attached to said casing around the first opening and defining a push button covering said first opening or attached to a push button covering said first opening, defining a hermetically sealed closed compartment within said casing; a Printed Circuit Board (PCB) housed inside the closed compartment and bearing a protruding electric switch component pushable by the push button; a protective frame, housed inside the closed compartment, surrounding the perimeter of the protruding electric switch component, and attached to the PCB through several connection legs distributed around the protruding electric switch component. The compressible elastomeric body includes protruding elements surrounding the protective frame to transmit shear forces, parallel to the PCB, from the push button to the PCB through the protective frame and connection legs without affecting the protruding electric switch component.

Abstract: A waterproof electric push button switch assembly having a closed compartment and an electric switch housed inside the closed compartment, the electric switch having connected thereto cables coming out of the compartment which is arranged inside a casing with a cavity with two openings, a first opening hermetically sealed by a compressible elastomeric body attached to the casing, and a second opening hermetically sealed by a cover. The elastomeric body extends into the cavity of the casing providing a surface supporting the electric switch and the cover has on its inner face a tubular wall which is inserted into the cavity of the casing and contacts the elastomeric body along the perimeter. The tubular wall completely surrounds the switch and assures its waterproofness.
