(Zehnfacher Reaktions-Apparat mit Stöpsel-Kontakten)
Description: This is a 10-key switch, which can allow each finger
to make a response and close a set of contacts. With this device,
a subject could be asked to respond with just one hand or just
one finger, thus making it easy to study inhibition effects.
