This is a switchable capacitance bank. It allows you to add the capacitor as needed by flipping the switch. It is great for the ZVS tesla coil. It also works great to balance the capacitance in a system. It is easy to use just put it in line where you need the capacitors. I added a test video so you can connect it to a ZVS tesla coil. It will tune the coil quickly. It can also be used for AC and DC power. The Capacitors values are 10nf, 22nf, and 47nf.
