ABSTRACT:
A multi-instruction switch includes a control disk, an anchor member and a depressing element. The control disk can drive a first conductive element to rotate relative to the anchor member. The anchor member has a terminal connector which includes a common terminal, a first terminal, at least one second terminal and a third terminal. A second conductive element located beneath the depressing element can move up and down relative to the depressing element to connect a circuit. The first conductive element has a plurality of contact arms mating the terminal connector. One of the contact arms is connected to the common terminal in normal conditions. Other contact arms are connected alternately to contact zones and non-contact zones of the first and second terminals to generate a plurality of signals. By pressing the depressing element to connect the common terminal and the third terminal, the signals can be output.
