Eisco Labs Contact Key, Telegraphing/Morse Code, Double

Dual Spring Arm Design - two independent spring arms with press knobs and contact studs give students hands-on control over circuit signaling, making Morse code and telegraphing demonstrations clear and repeatable, Built for Classroom Circuit Labs - suited for physics and electronics classrooms studying circuits and signal transmission, with a double-key layout that lets instructors show how two separate switching points operate in one compact unit, Durable Plated Connecting Strips - plated connecting strips maintain reliable electrical contact through repeated use, reducing the need for frequent replacements during busy lab sessions, Compact and Bench-Ready - at 5" 2. 5", the key fits easily on a student desk or demonstration bench without crowding other apparatus, and its solid construction handles the handling typical of classroom environments, Supports Signal Transmission Study - the double contact configuration lets teachers illustrate how keyed signals are generated and transmitted, reinforcing core concepts in electricity, communication technology, and circuit behavior.
