TOUCH SENSOR MODULE METAL

Specification: The metal touch sensor module is a sensitive switch device that triggers a digital signal when physical contact is made with its conductive metal surface. In a laboratory setting, it is frequently employed in custom instrumentation for touch-sensitive controls, human-machine interface prototyping, or as a non-mechanical switch for clean-room automation setups.
