    Light Proximity Switch

    Project Image

    Overview

    This is a relatively low cost accessibility switch activated by waving over or very lightly pressing the activation area. The output from the switch is a standard 3.5 mm cable.

    Usage

    The switch is well-suited for use by small movements of a finger or larger gross movements of a hand or limb. 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. The switch has a removable base so it can more easily be positioned to access small movements.

    Hi, not sure where to direct this. Just finished assembling one and there is a typo in the assembly instructions. The 330 capacitors are referred to as *33 microfarad* should be *33 picofarad*. They are labeled correctly in the kit, just not the documentation.

    This is the perfect spot, @marchache1717. Thanks for catching that.

    Edit: We’ve updated the assembly guide.
