Abstract:
A touch switch apparatus emulating a mechanical switch includes a field effect sensor and an electric field stimulator mechanically associated with the field effect sensor. A field generation signal applied to the field effect sensor causes an electric field to be generated thereabout. The electric field stimulator can be moved between first and second positions with respect to the field effect sensor. When moved into proximity with the field effect sensor, the electric field stimulator disturbs the electric field. A detection circuit coupled to the field effect sensor detects and responds to the disturbance to the electric field.
