Embodiment Construction

[0007] From attached figure 1 It can be seen that the embodiment of the music key type step ladder provides three layers of steps, and each layer of steps is composed of 4 ladder keys that are close together and can move up and down independently. The number of layers can be one to multiple layers, and each layer of steps can be composed of one or more independent ladder keys), from the attached figure 2 It can be seen that there is a pair of moving contacts (3) under each ladder key. When the ladder key (1) is stepped down, the ladder key (1) moves downward along the rotating shaft (2) to compress the return spring (4) , and then move downward to press down the moving contact (3), so that the moving contact (3) is closed, and the closing signal enters the electronic organ circuit ( 5), when the ladder key (1) is released, the ladder key (1) moves upward under the action of the return spring (4), and the moving contact (3) restores (disconnects) and waits to be stepped on ag...
