Abstract
An impact resistant switch mechanism is disclosed which includes a switch disposed within a housing of a device, such as a communication device or the like. The housing has an opening formed therein through which the switch may be operated from outside the housing. An extension of material extends from the housing about the housing opening, and a shaft extending through the extension of material and the housing opening is coupled at one end to the switch for operation thereof. A knob is attached to an opposite end of the shaft and is disposed over the housing extension. The knob is rotatable about the extension and will come into contact with the extension if a force is applied to the knob before transmission of the force into the switch, which could result in possible damage to the switch.
