Abstract
An electronic percussion instrument has a covering section 7A for covering the rim switch 5 on the outer periphery of a pad member 7 and a switch compression section 13 and two grooves 14 are provided on the back surface of the covering section 7A. In the switch compression section 13, a pressing surface 13a is made into a curved surface protruding towards the rim switch 5. The result is that striking forces for pressing the rim switch 5 are concentrated on the switch compression section 13 so as to enable to reliably and effectively transmit the forces to the rim switch 5 by elastic deformation of the switch compression section 13, regardless of the hitting direction of the drumstick on the rim section.
