Not only will the inductive load of the solenoid primary generate destructive voltages, as in a Kettering style field collapse, also the contactors in the solenoids can provide a dirty arcing when opening. Common switches as well may produce an electrically noisy opening. In modern electronics time periods, the operation of a common switch looks like a week long electrical storm. Diodes and capacitors across the contacts are used to silence such noise. Lynn E. Hanover In a message dated 8/22/2013 6:47:37 P.M.
