Irc Ww4j Precision Resistor Switched Gang Array 10 Ohm

This is a collection of 10 (ten) IRC precision (0.5% tolerance) wire-wound power resistors, arranged on a circular phenolic disk a bit over 3-in in diameter, and wired sequentially to a 12-position rotary switch. Each resistor is wired in series thru the switch, therefore the switch will place across the terminals (the cut wires in the photos) any value from 10 ohm to 100 ohm, in 10 ohm steps. The additional 2 steps on the switch are open and short, respectively. The whole thing mounts in a panel hole via a threaded post (similar to standard potentiometer) under the knob. The resistors themselves are power wire-wound, type WW4J, with labeled accuracy of 1/2 percent (0.5%). The resistors are in excellent condition, with no discoloration due to overheating. The switch clicks thru all positions, appears to be a sealed unit, although I don't have any way of thoroughly testing. These resistors alone list for $5+ each at 1% tolerance; the ones in this assembly are all 0.5% tolerance. The assembly can be used as a precision resistor array, or the individual resistors can be removed with minimal fuss for a nice collection of precision 10-ohm power resistors.
Condition Used :
An item that has been used previously. The item may have some signs of cosmetic wear, but is fully operational and functions as intended. This item may be a floor model or store return that has been used. See the seller’s listing for full details and description of any imperfections.
Seller Notes Limited testing with a VMM reveals item to function as stated. I don't have precision multimeter to thoroughly test so selling as is, therefore bid accordingly.
