I am almost finished with my tesla coil, I have a quick ?

Does anyone know where I can get or find a motor operated type of switch that will keep the current oscillating? Thanks so much.

Hi,

A Tesla coil can use a self interrupting relay circuit to pulse a battery powered primary coil. One design that has been recommended (not endorsed by Science Buddies) can be downloaded from this page:

I have seen Tesla coil designs that use solid state oscillator circuits or synchronous motors to control the primary coil, but I have no expertise on them.

Here is a set of plans found on the internet that has construction details for an AC based design, though be careful to read the safety notes. You have to be careful to limit coil currents or the apparatus can be lethal:

Here are other sites that might prove useful:

Science Buddies at one time provided instructions on building a Neef relay circuit for use in Tesla Coil style high voltage transformers/spark coils but many people had trouble getting the design to work. They appear to have taken that resource off the Science Buddies site. There is a lot more information available by searching the internet (you can try using www.google.com to search for “tesla coil”), but unfortunately I am not aware of experts on this forum with extensive coil building experience, and you need to know what you are doing or the project can be quite dangerous.

I hope this info will help you solve your problem.

Best regards,
