Wanted: Knife Switch Parts (or HUW Switch Box)

[Rob Fast]

here are the only pics I have courtesay a gentleman out of Southhampton many years ago, Black out switch and switch throw.

[Bruce Parker (RIP)]

Taking my first pic and using photo editing software I stretched the wiring diagram on the lid to be a rectangle and scaled it to a known size (based on the lid dimensions), then cleaned it up to come up with this. I may re-draft a new one or clean this up some more and glue a print of it in my new box.

I think the same door/hatch blackout switches were used on the 2K1/2K2 15-cwt Wireless Boxes. One on the upper left corner of the rear door coming into the vehicle and the other on the upper latch side of the Generator Compartment door.

Bruce. Do you have any commercial electrical contractors in your area that have been around since the 1950's or so? Would not hurt to pop into them one day with the photos of that knife switch setup. They just might know what other uses it had and where to source bits.

Bruce,

I had a look on ebay to see if there were any switches that seemed to have the correct characteristics (shape of contacts, location of screw terminals, etc) and I came across this box of old Leviton model 9915 switches.

ebay item number: 332206864707

I certainly don't know if the scale is correct and the price is not very attractive but they do seem to be a very close match to the details I can make out in your image.

Having had a quick look at other vintage Leviton models it appears that the contacts are held in place by screws coming up from under the base so they should be easily transferrable to a new base plate.
