Overview

This is a relatively low cost accessibility switch activated by lightly pressing the contact pad. . The switch is comprised of a control box and a contact pad attached by cable to the control box. The output from the control box is a standard 3.5 mm cable.

Usage

The switch is well-suited for use by a finger. This switch can be plugged into any standard 3.5 mm AT interface. It can also be used with the Xbox Adaptive Controller. Multiple switches can be used to get input from more than one finger. The switch can be mounted using adhesive on the rear surface of the contact pad.

NOTE: This design relies on skin conductance, so it may not work well for users with very dry skin or an inability to sweat.
