Abstract
An analog sensor depressible by a single human finger/thumb. Depressive force is applied to a dome-cap and to analog materials for varying an analog output of the sensor responsive to varying force applied by a single finger or thumb. Depressive force causes the dome-cap to bow downward passing through a user discernable threshold, causing a snap-through tactile sensation. In some embodiments the dome-cap is metallic.
