Abstract:
1. An annular multi-instruction switch, comprising: a circuit board which is wired to connect at least one common terminal and a plurality of signal terminals to form multiple instruction switches, each of the instruction switches has an elastic contact element built with a return force, the circuit board also having a plurality of displacement portions, wherein the elastic contact element is always connected with the common terminal; and an annular click member which has actuating portions with moving portions reciprocally moving up and down through the displacement portions such that the annular click member performs a vertical displacement relative to the circuit board to make the annular click member situated at a normal position and an instruction generating position, an installation opening in the center in cooperation with the circuit board to form a housing space, and contacts corresponding to the elastic contact elements such that when the annular click member receives a force and is moved to the instruction generating position the contact directly connects and presses the elastic contact element and the return force is stored and the common terminal and one signal terminal are connected to generate and output an instruction signal; when the force is released from the annular click member the elastic contact element bounces back due to the return force to the normal position.
