Tactile feedback plunger switch |
摘要 |
A tactile feedback switching mechanism having a plurality of switching states. The tactile feedback switching mechanism includes a plunger switch having a plunger. When the plunger is displaced a given distance the switch changes state. A covering lies at least over the plunger switch and includes a border section and a deformation section. The covering may be formed from an elastic material such as an elastomer. When a user depresses the plunger, confirmation of a change in the state of the switch can be tacitly sensed by a change in resistance provided by the covering. The resistance of the covering changes by deformation of the deformation portion of the covering while the plunger is depressed.
