摘要： A pedal board for musical instruments. Pedal mounting, guide, and electrical switch mechanisms are provided in a pedal board for an electronic organ. Each pedal (50) is mounted by a cylindrical pin (54) attached to the back end (56) of the pedal and to the base (52) of the pedal board by an interference fit. A similar, guide pin (60) is attached to the front end (62) of the pedal by an interference fit. The guide pin fits loosely in an aperture which limits lateral movement of the pin and, thence, of the pedal itself. The lower end of the guide pin actuates an elastomer electric switch (68) when the pedal is pressed down. The elastomeric electric switch is mounted on a printed circuit board (114), and includes a chamber (102) having a bell-shaped wall (104) attached to a support strip by weakened edges (126) and may be enclosed at the bottom by a diaphragm (124). The wall carries conductive elements (122). The conductive element shorts contacts (118) on the printed circuit board when the chamber is compressed by the guide pin. Pedal board tension and resiliency is providing by the mounting pin and/or by a bias spring (148).
