Kosketuskytkimiä
Kosketuskytkimiä, also known as touch switches or capacitive switches, are a type of electrical switch that activates when a conductive object, such as a human finger, comes into proximity with its sensing surface. Unlike traditional mechanical switches that rely on physical contact to complete a circuit, kosketuskytkimiä use capacitive sensing technology. This technology detects changes in capacitance that occur when a person's body, which is conductive, approaches or touches the sensor.
These switches are typically made with a conductive material, often a printed circuit board (PCB) trace, covered
Kosketuskytkimiä offer several advantages. They are durable as there are no moving parts to wear out, making
