Collins ART-13 Original Sperti Electronics CYS 24163 / SP IS-21 HV Vacuum Switch New in Box!

This Collins ART-13 Original Sperti Electronics CYS 24163 / SP IS-21 HV Vacuum Switch, is New in the original Box and was made in 1942 when the ART-13 was first built!

This is a great find as relays tend to fail after so many cycles. They also tend to get broken so this brand new replacement is rare to find and nice to have on hand.

I have a limited supply so do not hesitate to pick one up as a spare or to replace one if it is not working properly. 

If you are in need of the line of Connectors for the Collins ART-13 please see my other listings as I have most of them needed!
