Aircraft Spruce
carries a solid-state “Superswitch” contactor from Lamar Technologies. Has
anyone used these?
FWIW there are a
number of NOS 24V 50A Leach contactors for sale on Ebay. I got a few with the
idea of replacing the hydraulic pump relay supplied by Lancair. They arrived in
sealed original packaging- no date of manufacture but my guess is 50’s or 60’s.
The exposed insulation appears to be sound and the units function
properly.
The Leach unit
weighs 8.12 oz., about 5 oz. less than the Lancair style and the windings
measure 152.7 Ohms vs. 62.7. The pump draws about 30A at system pressure
according to the Oildyne chart. Comments?
Thanks- Bill
