(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
