Do you mean ACB-4 switch?
If the relays are missing their covers it sounds like the previous owner
also had issues. It a good idea to look inside at things when purchasing, I
have been burned too on used items that looked mint on the outside. Internet
photos just show tape around the torrid (does yours look like this?):

assist, the previous Comtek owner is a silent key.

Over the years I have owned ABC 160 ABC 80 and ABC 40 meter 4 Sq switch
box... My 80 meter box took a lightning hit last summer.
I picked up a used on one of the Ham reselling sites...
Getting ready for CQWW-CW I installed it and to my surprise... it's not
working
as it should.. Examining the unit and wringing out the truth table the
relays
are A-OK.
There missing there covers and the torrids are wound on them but there
is
NO fiberglass tape and there held in place with a bead of RTV across the
top.
Again the DXeng site says there wound on fiberglass tape my old unit
has
the tape
A good deal my be not so GOOD !
