Abstract: A computer security device for controlling the passage of data signals to and from a computer allows the operator to control access to that computer by outside parties. The device is a switch that can be connected to or disconnected from a computer in modular fashion. The switch may include a rotatable lever connected to a contact body with a plurality of data paths thereon. The communication paths are connected or disconnected to data lines by arcuate movement of the lever. The switching mechanism may be a spring board within a platform. Moving the spring board in and out of the plane of the platform connects and disconnects data lines to the computer. The switch may be a rotary switch that turns to connect and disconnect the data lines. The device may also be a single throw, twelve pole switch that allows data connection or disconnection.
