<p>An input/output device (1) for electrical equipment has a lamp (5) and a switch (3). A circuit board (7) contains a light emitting portion (25) of the lamp and a first and second trace portion (23) of the switch. A continuous membrane (13) of resilient material extends over the light emitting portion of the lamp and the first and second trace portions of the switch. A light pipe portion (35) of the lamp, capable of transmitting light from the light emitting portion of the lamp, is formed in the membrane. An actuation portion (33) of the switch is also formed in the membrane. The membrane also contains an electrically conductive portion (43) of the switch. When the actuation portion of the switch is deflected by a user's finger or other force, the electrically conductive portion of the switch connects the first and second trace portions of the switch. The continuous membrane protects the electrical equipment from electrostatic discharge and contamination through the input/output device. <IMAGE></p> |
