Claims

[Scope of utility model registration request]

A plurality of electrodes of a switch are arranged on an insulating substrate, an insulating elastic member has a movable contact of the switch arranged at a position facing the electrodes, and a switch is pressed against the elastic member in conjunction with a key. and a roller-shaped actuator that rolls and presses the movable contact through deformation of the elastic member to short-circuit the electrodes, and the roller-transfer surface of the actuator on the insulating elastic member responds to touch in response to piano key displacement. A keyboard switch for an electronic musical instrument characterized by being formed on an uneven surface that receives a load.
