Mechanical characteristics of micro-switches adapted for the physically disabled.
The object of this study was to measure the mechanical characteristics of several commonly used adapted switches in order to demonstrate the feasibility of collecting quantitative descriptions of switch performance. A stepping motor was used to drive a digital micrometer vertically towards the tested switch and proving-ring strain gauges recorded the operating force. Measures of activation and deactivation forces, travel and switch compliance were compared; several clinical examples illustrate the functional application of these results. It is anticipated that this information will permit clinicians to prescribe switches in a more accurate manner.
