Abstract:
An actuating device is proposed for an electric / electronic device within an in particular flame-proof housing, said electrical / electronic device comprising an essentially linearly movable on / off lever. In order to provide such an actuating device being accessible on the exterior of the respective flameproof housing and allowing mechanical actuation of the respective on / off lever without adversely affecting the flameproof housing, the actuating device comprises at least a rotatably mounted handle disposed on the outside of the housing and a shaft connected with it in a rotatably fixed manner, said shaft being guided into the housing interior and there being connected movably to the on / off lever by means of a transformation gear for transforming rotational motion into linear motion.
Abstract:
The present invention relates to a push-button switch comprising: - a box-like supporting structure (2) defining an inner chamber (8), the box- like structure (2) having at least one opening (9) communicating with the inner room (8) and having an opening axis (Z-Z) ; - a push-button (21) to be matched with the supporting structure (2) at said opening (9) ; - mechanical coupling means (22) for coupling the push- button (21) to said structure (2) such that the push- button (21) is allowed to be fastened to the supporting structure (2) while being movable relative thereto in a direction substantially parallel to the opening axis (Z- Z). The push-button switch is characterized in that the mechanical coupling means include a holding and guide frame (22) for the push-button (21), which can be fixed to the supporting structure (2) and can be interposed between the push-button (21) and the structure (2).
Abstract:
The invention relates to personal communications devices and casings for such devices. The casing for a portable communications device comprises at least a front face having edge portions, a housing element having a portion that extends over the edge portions of the front face, the housing element being fixed in a position such that the portion of the housing element overlying the edge portions of the front face and the front face are pressed together so as to hold them firmly with respect to each other.
Abstract:
A casing for a portable communication device having an operating face comprising a fragile input region providing recesses for operation of respective user input elements and a protection arrangement protruding beyond the fragile input region having an external profile that provides a plurality of contact points defining a contact plane such that when placed face downwards on a generally planar surface, the fragile region is spaced therefrom and impulses received on contact between the generally planar surface and the operating face are substantially dissipated away fom the fragile region.
Abstract:
The invention relates to portable communication devices and in particular to the casings of such devices. The casing has an operating face providing a key arrangement for user operation of the device. A operating face provides recesses in the input region for operation of the keys.
Abstract:
A switch (100) and a method of manufacturing the switch are provided. In one embodiment, the switch (100) includes a button (110); a membrane (120) located beneath the button; a first elastic member (130) and a second elastic member (140) that are located between the button and the membrane. The membrane is activated upon being deformed in a first direction by the second elastic member to a predefined extent. The first elastic member is operable to be deformed in response to a force applied on the button in the first direction, and to prevent the second elastic member from contacting with the membrane until magnitude of the force exceeds a threshold. The switch provides a quickly responsive yet durable input mechanism and allows for a smooth typing experience. A keyboard is also provided.
Abstract:
The invention relates to the use of a push button device, described below, according to one of the subsequent claims for actuating a functionality in a motor vehicle, and also to a push button device of a functionality of a motor vehicle, wherein the push button device has: - a mechanical and/or electric function controller which has a first control state and a second control state; - a push button element with a manually actuable push button surface, wherein the push button element can be pressed from a disengaged state into a pressed state by way of a pressure force, wherein the function controller has the first control state when the push button element is in the disengaged state, and the function controller has the second control state when the push button element is in the pressed state, wherein the push button device has: - a first spring which acts upon the push button element with a first force in the direction of the disengaged state, - a retaining device which defines the position of the disengaged state of the push button element, wherein the push button device has an adjuster by means of which the position of the disengaged state of the push button element is adjustable.

Abstract:
A safety mechanism for medical treatment devices (20) includes a switch actuator (16) that depresses a power activation switch (14) after movement in a first direction followed movement in a second direction. The safety mechanism thus prevents accidental or unintentional delivery of power to a heating segment (28) of the medical treatment devices (20).
