Abstract
Disclosed is a multi-step pressurized switch providing various signals in response to variation of pressure applied thereto. The multi-step pressurized switch includes a switched PCB connected to a PCB of an electronic device and having at least one or more contact points on the top, and an elastic plate settled on the top of the switched PCB and electrically connecting the contact points with each other if there is pressure. The elastic plate includes a first projection protruding upward from the edge of the elastic plate, a second projection joining with the first projection and protruding in the same direction with the first projection, and a first slope bending down toward a direction opposite to the first projection from the edge of the elastic plate.
Claims29
A multi-step pressurized switch, comprising:
- a switched PCB connected to a PCB of an electronic device and having at least one or more contact points on the top;
- and
- an elastic plate settled on the top of the switched PCB and electrically connecting the contact points with each other if there is pressure,
- wherein the elastic plate comprises:
- a first projection protruding upward from the edge of the elastic plate;
- a second projection joining with the first projection and protruding in the same direction with the first projection;
- and a first slope bending down toward a direction opposite to the first projection from the edge of the elastic plate.
A multi-step pressurized switch, comprising:
- a PCB on which a plurality of contact parts is formed;
- and
- an elastic plate settled on the PCB and electrically connecting the contact parts of the PCB,
- wherein the elastic plate comprises:
- a base fixedly settled on the PCB and shaped in a belt slanting outward;
- a first contact region disposed in both internal sides of the base and extending toward the center of the base;
- a second contact region configured in a convex at the center of the base;
- and connectors linking the first and second contact regions together,
- wherein the first contact region meets the contact part of the PCB if the second contact region is pressed and then the second contact region meets the contact part of the PCB if the second contact region is continuously pressed.
