A sensor is provided with a conductor layer, a sensor layer including a plurality of sensor units, and a separating layer which separates the conductor layer from the sensor layer, the sensor unit is formed of alternately arranged first and second electrode elements, and sensitivity on an outer periphery of the sensor unit is higher than the sensitivity in a central portion of the sensor unit.

A keyswitch includes a base having a pillar, a cap having a rib and movable relative to the base, a sleeve rotatably sleeving the pillar and having first and second top surfaces and convex and concave portions, an elastic member abutting against the sleeve and the base, and a resilient arm abutting against a first or second position on the convex portion with rotation of the sleeve. When the resilient arm abuts against the first position, the rib abuts against the first top surface to prepress the elastic member for generating a first preload. When the cap is pressed for moving the sleeve downward, the resilient arm moves from the first or second position to the concave portion. When the resilient arm abuts against the second position, the rib abuts against the second top surface to prepress the elastic member for generating a second preload larger than the first preload.
