The Knife Switch is a durable, manually operated electrical switch designed for controlling the flow of current in low to medium voltage circuits. Featuring a robust metal lever (the “knife”) that pivots into a contact, this switch provides a visible break in the circuit, making it ideal for both safety and operational clarity in laboratory, educational, and industrial electrical applications. Constructed from high-quality, corrosion-resistant materials, the Knife Switch ensures reliable operation and easy maintenance. It is widely used for isolating electrical equipment, testing circuits, and demonstrating electrical principles in academic and research environments.
