Lascells Reaction Timer Switch

A Reaction Timer switch for use with Lascells timers, this apparatus allows students to test their reaction times to a random event. The subject presses the START button and after a short random delay the light comes on. The subject then has to press the STOP button as quickly as they can in response to the light. A connected timer (not included) records the interval between the light coming on and the stop button being pressed.

No power supply is required. However, please note: A Lascells timer (TMH-825-100 or TMH-835-100) is required to use in conjunction with the reaction timer switch.
