The Electrical Interlock Works Using The &Ldquo;Closed Circuit Principle&Rdquo;, Meaning That When The Control Voltage Is Not Connected To The Coil. The Switches Provided With A-Type Interlocks Cannot Be Turned To The On-Position And Switches With L-Type Interlocks Cannot Be Turned To The On- Or Off Positions.
