Abstract
A tap selector anti-arcing system is used with rotary tap selectors to prevent arcing as the selectors move from one tap to the other. A lockout mechanism includes a pair of lever arms located adjacent two Geneva gears. The Geneva gears include pins disposed on opposed sides thereof to actuate one lever arm to thereby move the other lever arm to interferingly engage the pin on the other gear if the gears move simultaneously to engage the neutral and eighth taps. An interrupter is opened by linkage connected to a cam disposed on the drive mechanism for the Geneva gears to open the circuit during the movement of the Geneva gears from one tap to another.
