A swirl ring for a plasma arc torch includes a body configured to at least partially surround and slidingly engage an electrode of the plasma arc torch. The body includes a first end and a second end opposite the first end, the first and second ends defining a longitudinal axis, and at least one protuberance extending from the second end in a direction of the longitudinal axis. The at least one protuberance is configured to engage a switch of the plasma arc torch for sensing a presence of a swirl ring in the plasma arc torch.
