Frequently Asked Questions
Q: What types of electrical switches and modules are available in this collection?
A: Our Electrical Modules & Switches collection includes rocker toggle switches, rotary encoders, DC boost/step-up power inverter modules, switching power supply boards, battery protection boards, lamp sockets, capacitor discharge tools, and more — covering a wide range of voltages and current ratings for both DIY and professional use.
Q: Are these electrical modules suitable for DIY home projects and professional installations?
A: Yes! Our electrical modules and switches are designed to serve both DIY hobbyists and professional technicians. Products like the 12mm Rocker Toggle Switch (32A, 250VAC) and the 45W Universal Switching Power Supply Board are rated for real-world applications, making them appropriate for home workshop builds, audio equipment, power tools, and light industrial use.
Q: How do I choose the right power module or switch for my project?
A: Start by identifying your circuit's voltage and current requirements. For DC-to-AC conversion needs, consider the 100W DC Boost Module (12–220V). For battery-powered tool builds, the 21V Battery Protection Board or an 18V Battery Connector Terminal Block are great starting points. Check each product's specifications carefully to ensure compatibility with your application.
Q: Do the battery protection boards work with standard 18650 lithium cells?
A: Yes — our 21V 18650 Battery Protection Board is specifically designed for 18650 lithium-ion cell packs. It provides over-charge, over-discharge, over-current, and temperature protection, making it a safe and reliable choice for custom battery pack assemblies used in power tools and DIY energy storage projects.
