Abstract

PURPOSE: To improve key touch in the surrounding of full stroke by turning off a switch which operates correspondingly to a key at the time of key non- depressing, and turning on the switch at the time of key depressing. CONSTITUTION: When a key 1' is depressed downward, the downward movement of the key 1' is promoted by the return power of a switch 3 in the on-state at the time of key non-depressing. After the switch 3 is turned into an off-state after return completion, an L-shaped actuator 9 integrated with the key 1' is separated from the switch 3, the weight of a key 1 is not affected by the switch 3, and made constant from the middle of stroke. As a result, the weight of a key can not be extremely heavy without being affected of the weight of the switch in the surrounding of full stroke, and touch in the surrounding of full stroke can be improved.
