An acoustic output device includes a base case whose internal space is formed as an arrangement space and in which an insertion hole communicating with the internal space is formed, a cover that covers at least a part of the base case, an elastically deformable waterproof sheet including a flat surface portion joined to the base case and a bag-shaped pocket portion inserted into the insertion hole, a push button including an operating portion to be pressed and operated and a working portion inserted into the pocket portion, a substrate that is arranged in the arrangement space, and a switch that is arranged on the substrate and operated by the working portion via the pocket portion.

A waterproof keypad module, comprising a waterproof film (7) which is in a pre-tightened state and which isolates a touch component from a bottom casing (4); an edge of said waterproof film being fixed at the position where a front casing (1) and the bottom casing (4) connect, and said touch component being supported on said waterproof film (7). The edge of said waterproof film is fixed at the position where the front casing (1) and bottom casing (4) connect, wherein the touch component may be completely isolated from the bottom casing (4) by means of the waterproof film (7); thus, even if a gap exists between the touch component and casing, water cannot pass through the waterproof film (7) and enter the bottom casing (4), thus achieving waterproofing of the keypad module.

The invention provides an axially actuating tactile electrical switch comprising a casing; a plurality of independent fixed electrical contacts arranged in a base of the casing, and a movable electrical contact comprising a peripheral portion resting on a portion of a fixed peripheral electrical contact and a central portion movable vertically downwards; a single piece actuating body made of elastic material comprising a peripheral portion, an actuating central part comprising a lower portion for actuating the movable electrical contact, and an upper portion for receiving an actuating force, forming a casing comprising an upper cover having a hole whereby a free upper end section of the upper portion extends axially; the cover has an internal retaining surface; and the actuating body has an abutment surface cooperating with the internal retaining surface of the cover to determine an upper rest position of the actuating body with respect to the casing.

A switch assembly including a socket, a top cap, and an intermediate cart located in the socket. The intermediate cart is slidable with the socket. The top cap is in a spherical or pivot engagement with the intermediate cart. An activation force of the sliding movement is lower than an activation force of the spherical or pivot movement.

A button is disclosed for use with an image capture device in an underwater environment. The button includes a movable plunger configured to cause actuation of the image capture device, and upper and lower components collectively defining an internal cavity that is configured to receive the plunger. The upper and lower components are configured and connected such that actuation of the image capture device is prevented until a threshold pressure is applied to the upper component that is greater than external water pressure applied in the underwater environment. The upper component includes at least one opening that is configured to allow water to enter the internal cavity to modify an internal pressure within the internal cavity so as to reduce the threshold pressure required to actuate the image capture device in the underwater environment.
