This invention is directed at a key lock switch having antistatic means. The antistatic means include a tubular element and a tubular antistatic wall which extends from a mid-plate and a tubular engagement portion which extends from the actuator of the switch. The antistatic wall circumscribes the tubular element in spaced relation. When the mid-plate is engaged to the actuator the tubular engagement portion is positioned between and in spaced relation to the antistatic wall and the tubular element.
