Taction Pad:
Clear,
adhesive backed, flexible, touch sensitive, plastic patch activated by the
slightest touch. When adhered to a surface or object, it acts like a switch.
Taction pads are available in four different styles. Taction pads only work with
Adaptivation's line of touch activated devices. Other devices can be used with
them when interfaced with a Link Switch or the Switch Scanner, also available
through Adaptivation.
