The Self-Calibrating Auditory Tone Infrared (SCATIR) Switch is a momentary-contact optical switch with auditory feedback.

The SCATIR switch works by detecting a beam of reflected pulsed infrared light.

It is suitable for use with a variety of control gestures, such as eye-blink, eyebrow movement, finger movement, head movement, and facial muscle movement. It can be activated at a distance so the controlling body part does not need to be in physical contact with the switch sensor.

Used to Adjust:

• Beep on/off
• Tone continous/beep
• Manual or self calibration
