Contact Key Switch

The Contact Key Switch introduces students to basic control components within an electrical circuit. Commonly used to demonstrate Morse code or signal-based communication, this switch temporarily completes a circuit when pressed, making it perfect for hands-on learning. Its tactile design offers immediate feedback, giving learners a real sense of how circuits operate in interactive systems. Whether studying historical communication or basic circuit control, this compact device makes el...
