Product Code : SCL-EE-12415
The Reversing Key Commutator is a physics laboratory switch used for reversing the direction of current in a connected DC circuit. It is designed for school physics labs, STEM classrooms, and electricity experiments where students need to observe how current direction affects circuit behaviour, galvanometer deflection, and electromagnetic effects.
Product Description
The Reversing Key | Commutator is an educational electrical apparatus used in practical physics demonstrations. It allows a teacher or student to change current direction without rewiring the complete circuit, making experiments faster, cleaner, and easier to repeat.
This apparatus is suitable for classroom demonstrations involving DC circuits, current reversal, polarity change, galvanometer response, and electromagnetism. The exact electrical rating, material, terminal design, and dimensions should be confirmed before publishing or procurement, as these specifications were not supplied.
Key Features
