Abstract
A pressure-sensitive switch includes a first substrate, a conductive structure provided on the first substrate, and an electrode unit disposed to face the first substrate with the conductive structure interposed therebetween. The conductive structure includes an elastic component extending to protrude from the first substrate toward the electrode unit, and an electrode layer covering the elastic component.

A pressure-sensitive switch comprising:
- a first substrate;
- a conductive structure provided on the first substrate;
- a second substrate;
- and
- an electrode unit disposed to face the first substrate with the conductive structure located therebetween,
- wherein the conductive structure includes at least two elastic components extending to protrude from the first substrate toward the electrode unit, and an electrode layer covering the at least two elastic components, and
- the at least two elastic components are spaced from each other and have different heights.
A touch panel comprising:
- a sensor that detects a touch location;
- and
- a pressure-sensitive switch disposed on the sensor, the pressure-sensitive switch comprising:
- a first substrate;
- a conductive structure provided on the first substrate;
- a second substrate;
- and
- an electrode unit disposed to face the first substrate with the conductive structure located therebetween,
- wherein the conductive structure includes at least two elastic components extending to protrude from the first substrate toward the electrode unit, and an electrode layer covering the at least two elastic components, and
- the at least two elastic components are spaced from each other and have different heights.
A manufacturing method for a pressure-sensitive switch, the manufacturing method comprising the steps of:
- forming, on a first substrate, at least two elastic components each extending to protrude from the first substrate;
- providing a conductive structure by forming an electrode layer to continuously cover each of the at least two elastic components and an exposed portion of the first substrate;
- and
- providing an electrode unit that is positioned to face the electrode layer, wherein
- the at least two elastic components have different heights in the step of providing the conductive structure.
