Tower-Power is a computer switch adapter designed for use by individuals with cerebral palsy, neurological or upper extremity disabilities, or spinal cord injury. The device is mounted over the power button on a PC, and connected to a switch (not included) placed where the user can reach. This enables the user to turn on the power from a more convenient position, or using a switch that requires less dexterity or force. This device comes with solenoid casing (aluminum housing with LED light), a Velcro strap, and an Allen key. COMPATIBILITY: For use on most desktop computers. SYSTEM REQUIREMENTS: Desktop computer with "soft-touch" power button and a switch with a standard 1/8 inch (3.5 millimeter) mono jack.
