Abstract: An apparatus for providing a switch mechanism comprises a housing and a pressure sensitive device mounted to the housing. An actuator is moveably connected to the housing to enable the actuator to move along an axis towards and away from the pressure sensitive device. A resilient member has a first end connected to the actuator and a second end connected to the pressure sensitive device.

Abstract: A touch device comprises a base, a membrane pressure sensor arranged on the base, a touch sensing layer covering the membrane pressure sensor, and a force feedback structure arranged on the lower surface of the touch sensing layer and electrically connected to the membrane pressure sensor. The membrane pressure sensor is configured to generate a pressing signal related to the force applied to it, and the force feedback structure is configured to receive the pressing signal and generate a feedback force corresponding to it.

Abstract: A pressure sensor has a base layer, a supporting structure arranged on the base layer, and an elastic layer disposed above the base layer and the supporting structure. The elastic layer has a curved lower surface that is recessed away from the base layer. The curved lower surface, the supporting structure and the base layer define a cavity with an arched top wall. A first electrode, a second electrode, and an elastic body are all arranged within the cavity, such that when the elastic layer is elastically deformed in a direction of the base layer, the variable resistance elastic body electrically connects the first electrode with the second electrode, so as to generate a first signal related to the elastic deformation of the variable resistance elastic body.
