Abstract
A key press switch includes a main body portion configured to contact a pseudo hammer of the electronic piano and a contact portion provided in a part of the main body portion to contact the pseudo hammer. The contact portion includes a first contact portion and a second contact portion located closer to the fulcrum than the first contact portion. The contact portion is configured such that a contact position with the pseudo hammer is shifted from the first contact portion to the second contact portion in accordance with the key press amount of the electronic piano from the amount at which, in a standard acoustic piano, the damper load starts to be applied until the amount at which, in a standard acoustic piano, the damper load has been fully applied.
