The TruCom XK-24 Programmable Keypad from X-Keys offers 24 dedicated keys in a compact footprint and an RS-232 serial computer connection. The K-24 is designed to replace legacy serial keypads sending ASCII. Programming software is available for download.
The choice between membrane, low-profile, and mechanical switches determines typing feel and noise. Consider ergonomics and layout sizes (full-size vs tenkeyless) based on desk space and numpad reliance. Available from $246.95.
Keyboards are passive peripherals with almost zero cost of ownership. Wireless models may require occasional battery replacements, but energy costs are negligible.
Common Failure Modes
Liquid spills and physical debris are the primary killers of keyboards. Mechanical switches can develop 'chatter' (registering double keystrokes), while membrane domes lose elasticity.

Mechanical keyboards can last for decades due to durable individual switches. Membrane keyboards degrade faster as the rubber domes lose their elasticity.
