A rotating electric switch includes a shaft with a side hole and a biasing member in the side hole for outwardly biasing an electrically-conductive bullet. The bullet is in electrical communication with a shaft conductor in a bottom hole of the shaft. A liner insulation cap placed over the shaft has a hole in the liner insulation cap sidewall covered by an electrically conductive sleeve. The switch achieves a non-conducting state by rotating the shaft until the head of the bullet is retracted within the sidewall of the liner insulation cap. A conducting state is achieved by rotating the shaft until the bullet extends through the hole in the liner insulation cap sidewall to electrically contact the conductive sleeve. Further embodiments may include an electrically-conductive inner tube in the side hole of the shaft and one or more grooves defined in the interior surface of the liner insulation cap.
