電子楽器のタツチレスポンススイツチ装置。 An electronic musical instrument comprising a touch response switch in which a first movable contact and a second movable contact sequentially contact a first fixed contact and a second fixed contact, respectively, in response to a keystroke, and a volume corresponding to the keystroke speed is obtained from the time difference between the contacts. In the touch response switch device, the touch response switch has a first touch response switch.
A dome-shaped body, a second dome-shaped body connected to the top of the dome-shaped body, a dome-shaped body connected to the top of the dome-shaped body and projecting downward from the top, and a cylindrical body connected to the top of the second dome-shaped body are integrally formed. an insulating elastic body comprising the first movable contact at the top of the first dome-shaped body, the second movable contact at the bottom of the dome-shaped body, and a third movable contact at the top of the second dome-shaped body; a substrate including the first and second fixed contacts and a third fixed contact,
The first, second, and third movable contacts are configured to sequentially contact the first, second, and third fixed contacts by sequential deformation of the first dome-shaped body, the second dome-shaped body, and the dovetail-shaped body by pressing the key. The key is arranged below the key with a gap therebetween, and the sound volume corresponding to the keystroke speed is emitted when the third movable contact and the third fixed contact are closed, at least during weak keystrokes. Touch response switch device for electronic musical instruments.
