Demonstration Electromagnetic Relay Experiment Instrument Key benefits Reliable performance: Manufactured for stable characteristics to deliver consistent and accurate results during experiments and demonstrations. Clear demonstration of circuit control: Shows the basic relay principle of using an electromagnet to switch a circuit, making abstract concepts tangible for students. Durable and portable: Constructed from plastic and metal for lasting use. Compact and lightweight for easy handling, storage, and transport between classrooms or labs. Easy integration: Designed for use with a 9V supply and readily pairs with indicator lights or small demonstration motors for practical experiments. Main features Function: Electromagnetic relay that demonstrates coildriven switching of an armature to control external circuits. Compatibility: Operates from a 9V power supply and can be connected to indicator lights, demonstration motors, or other lowvoltage controlled devices. Materials and size: Built from plastic and metal; compact footprint and low weight for classroom and lab use. Performance: Stable electrical and mechanical characteristics for repeatable demonstrations and student experiments. How it works When the coil is energized, the iron core becomes magnetic and attracts the armature, closing or opening the contact as designed. When coil power is removed, the armature releases and resets to its original position. This visible action demonstrates switching, control logic, and basic electromechanical conversion in simple circuits. Practical applications Classroom demonstration: Show the relay switching action to illustrate electromagnetism and circuit control in physics lessons. Handson student experiments: Build simple controlled circuits using indicator lights to observe on off behavior or connect a small demonstration motor to show controlled switching. Mechanical and electronics labs: Use as a teaching aid for experiments on relaybased control systems and electromechanical interactions. What customers can expect A straightforward teaching instrument that helps students visualize how relays control circuits. Compatibility with standard 9V educational setups and easy connection to common demonstration components. A compact, durable unit suitable for repeated classroom use and practical lab activities.
