5PCS Educational Single Pole Knife Switch SPST Switch Physics Lab Single Pole Single Throw Switch for DIY Science Projects, and Classroom Teaching Equipment

5-Pack of SPST Knife Switches for Your Physics Lab or Classroom What's Included: 5 x SPST Knife Switches (single-pole, single-throw) Each switch features a durable plastic base with brass poles and knife for reliable connections Hands-On Learning for All Levels: Whether you're demonstrating simple circuits, exploring series and parallel connections, or building a fruit battery, these switches provide a clear, tactile way for students to engage with physics principles. Each switch is mounted with screw-type binding posts that work seamlessly with alligator clip wires or bare copper leads. Built for the Classroom: With a low-voltage rating (6V-36V, up to 6A), these switches are safe for school use. The rugged construction is designed to withstand frequent handling by multiple students—year after year. Note: These switches are intended for educational demonstrations and temporary experiments only. Not suitable for household electrical wiring or permanent installations. Perfect for: Science teachers and STEM educators Homeschool science curriculum Student physics projects and science fairs Electronics hobbyists and DIY enthusiasts
