The navigation key includes a key cap, a frame, and a number of elastic connecting arms The key cap includes an annular operating portion configured for pressing, and a number of actuators extending from the operating portion towards the circuit board. Each actuator hangs above one corresponding switch, and contacts with the corresponding switch when the operation portion of the navigation key is pressed. The frame is arranged around the key cap, and is fixedly assembled to the circuit board. The elastic connecting arms interconnect the operation portion of the key cap and the frame to limit rotation of the key cap.
