Switching Assembly and Use Thereof in a Handheld Wireless Device For Remotely Activating A Remote Controlled System

A handheld wireless device according to any previous claim wherein the switching assembly comprises:

• a further electrical switch;
• a motion sensor adapted to sense motion of the handheld device and to output a signal indicative thereof;
• and
• a controller arranged to receive the signal from the motion sensor;
• and to operate the further electrical switch to switch off the transponder in response to a determination that the wireless handheld device has been motionless for a predetermined period of time.

A switch assembly comprising:

• a film of electrical insulator, which when in use is, positioned between an electrical energy store and a terminal of circuitry to be powered by the battery;
• a first electrical conductor connected to a mechanical switch assembly to provide electrical connection between the electrical energy store and the mechanical switch assembly;
• and
• a second electrical conductor connected to the mechanical switch assembly to provide electrical connection between the circuitry terminal and the mechanical switch assembly;
• the mechanical switch assembly being operable, when the switch assembly is in use, to switch between a first state in which the electrical energy store and terminal are in electrical connection via the first electrical conductor and second electrical conductor, and a second state in which the electrical energy store and electrical terminal are electrically isolated from one another.

A method of modifying a handheld wireless device for remotely activating a remote controlled system, the handheld wireless device comprising:

• a transponder arranged to transmit a wireless signal in response to a request received from the remote controlled system;
• and
• the method comprising fitting an mechanical switch assembly operable to switch off the transponder so that it will not respond to a received request;
• wherein the mechanical switch assembly is fitted such that the mechanical switch assembly acts to electrically isolate a battery of the handheld wireless device from a printed circuit board carrying the transponder.
