The Model 20 design features contact stacks that can be easily detached and replaced with a screw driver with no need to remove the unit from its cabinet. Heavy-duty silver alloy contacts of one half inch diameter provide for maximum life where only wiping the contacts assures positive operation. Ball-bearings throughout provide smooth operation and are sealed with aluminum covers to guard against dust and moisture. These enduring designs can be depended on for years of reliable service even in the most demanding allocations.
Contacts have a 20 amp rating with 2,400 watts per channel at 250 flashes per minute.
