Equip your classroom or laboratory with our reliable 1-Way On/Off Knife Switch. This single-pole, single-throw (SPST) switch is the industry standard for teaching fundamental electronics, allowing students to visually observe the physical "make or break" of a circuit.
Measuring 68mm in length, the switch features a sturdy, high-visibility green base and a heavy-duty metal lever. It is equipped with two color-coded binding post terminals (Red and Black) that allow for quick and secure wire connections via banana plugs or bare wire. Its simple, open-frame design makes it an ideal tool for physics experiments, hobbyist projects, and breadboard prototyping.
High-Visibility Operation: The physical lever clearly indicates the switch status (open or closed) at a glance.
Durable Construction: Features a robust metal knife-blade contact and a thick plastic base designed for repetitive classroom use.
Standard Binding Posts: Includes one red and one black screw-type terminal for easy integration into existing circuit kits.
Compact 68mm Footprint: Sized perfectly for portable science kits and space-conscious workstations.
Safe Low-Voltage Design: Optimized for DC circuit experiments and low-voltage educational applications.
Switch Type: Single Pole, Single Throw (SPST).
Action: 1-Way On/Off.
Length: 68mm.
Base Material: ABS Plastic (Green).
Terminal Type: Binding Posts (Compatible with 4mm banana plugs).
Contact Material: Nickel-plated metal.
Educational Science Kits: Teaching students about series and parallel circuits.
Physics Labs: Demonstrating the flow of electricity and circuit interruption.
DIY Hobbyist Projects: Simple power control for small DC motors, fans, or LED displays.
Prototyping: Quick-access power switching during low-voltage circuit development.
Can I use banana plugs with this switch?
Yes, the red and black terminals are standard binding posts that accept 4mm banana plugs through the top or bare wire through the side-hole.
Is this suitable for 240V mains power?
No. This knife switch is designed strictly for low-voltage educational and hobbyist DC circuits. It should never be used with high-voltage AC mains power.
How much space does it take up?
With a base length of 68mm, it is very compact and can easily fit into standard plastic storage bins or small project boxes.
