Many communication and control systems are designed to be operable using a single switch (or a small number of switches). A crucial step in the tailoring of a system to a patient who will operate it in this way is the selection of an appropriate switch, according to their physical abilities. We present a prototype switch simulator, capable of reproducing various types of switching action under computer control. This electromechanical device exhibits a force versus displacement characteristic (possibly incorporating hysteresis) selected by the user on the PC. In this way, the suitability of a variety of switching actions for a patient can be assessed, and the optimal choice identified. Furthermore, for patients with very particular needs, this device can implement switching actions which are difficult or impossible to reproduce in a passive mechanical switch. </span>
