An input device for switchable use between first and second computer systems. A controller of the input device can execute switching logic to direct a radio transceiver of the input device to switch an operating channel of the radio transceiver to a first channel monitored by the first computer system in response to a first event, and thereby, the input device can be utilized to insert data into the first computer system. The controller can execute switching logic to direct the radio transceiver to switch the operating channel to a second channel monitored by the second computer system in response to a second event, and thereby, the input device can be utilized to insert data into the second computer system.
