Scientifc Equipment Knife Switches, Screw Posts are educational electrical circuit components designed for school science laboratories, physics practicals, STEM classrooms, electronics demonstrations, and basic electricity experiments. These switches are used to manually open and close low-voltage circuits, helping students clearly observe how current flow is controlled in an electrical circuit.

The knife switch design provides a visible switching action, making it ideal for teaching open circuits, closed circuits, current flow, circuit control, series circuits, parallel circuits, battery-powered experiments, and electrical safety basics. The screw post terminals allow secure wire connections for repeated classroom and laboratory use.

Product Description

The Knife Switches, Screw Posts by Scientifc Equipment are practical laboratory switches used to control the flow of electricity in educational circuits. The switch generally consists of a metal blade, fixed contact jaws, insulated base, screw post terminals, and mounting arrangement as per supplied model configuration.

When the metal blade is lowered into the contact point, the circuit becomes closed and current flows through the connected components. When the blade is lifted away from the contact point, the circuit becomes open and current flow stops. This visible action helps students understand the basic function of a switch in a simple and effective way.

Scientifc Equipment Knife Switches with Screw Posts are suitable for use with bulbs, batteries, buzzers, motors, electromagnets, lamp boards, resistance coils, meters, and other low-voltage laboratory circuit apparatus.
