A switch structure includes switch means operable by the finger-tips of an operator, e. g. in an electrical typewriter or computer terminal. To impart a desired "touch" characteristic, the switch structure has a touch element overlying the contact surface, or switch actuation element, of the switch means, the touch element providing a degree of resilient resitance to touch and pressure by the fingertips. The resistance may be that of resilient solid or cellular material, displaceable liquid, or gas, or any combination thereof. |
