PROBLEM TO BE SOLVED: To miniaturize a switch by continuing forward rotation, repeating action, transmitting a pulse in the number of rotated protrusions, performing action reversing the right/left by reverse rotation, and transmitting a pulse in the number of rotated protrusions. SOLUTION: By forward rotation of a rotor 1, a cam roller 4 is pressed in a left direction by a protrusion 2, a cam lever 3 is tilted in a left direction with its center shaft 6 serving as the center. Simultaneously with forcing up the roller II to the height of the center of the protrusion 2, a coil spring 8 is press curved downward by the shaft 6 of the lever 3 by the dimensional height of the protrusion, a total unit of the lever 3 is moved to lower down. By left tilting and lower down moving, a contact of a left contact spring piece A is brought into press contact with a fixed contact (1), (3) of a base 12, a switch is turned on. Action is repeated by continuing forward rotation, a pulse (1) of a number of rotated protrusions is transmitted. By reverse rotation of the rotor 1, action reversing the right/left to the above is performed, a pulse (2) of a number of rotated protrusions is transmitted. |
