Advanced power switching panels ensure that high currents are applied to the ringing components only as long as it is needed. This keeps the tower safe from electric shock, prevents actuator overheating, and damage to the bell.

High voltage circuits should be switched through dry mechanical relay components because even the most advanced solid state circuits leak some currents. Solid state power switching is only acceptable when a dry master contactor enables the high voltage to the individual outputs only during ringing.
