Simple reaction switch

(Einfacher Reaktionstaster)
Description: This is a simple key or switch, much like a telegraph key that is used to indicate the finger movement which shows that a response has been made in the measurement of reaction time. The movement distance and force which are required to close the switch are adjustable. (Expanded caption Copyright 1998, Edward J. Haupt)
