For what it's worth in this case, the HA-1 manual recommends a contact protection network consisting of a cap & resistor for loads exceeding 2 ma & 50 volts.  There is a chart to help in selecting component values for various voltage and current combinations.

There is a nice copy of the HA-1 manual available on BAMA.  I have a couple of HA-1's which work fine with my Ranger and "modern' Halli transmitters.

Ok, enough of all of that, here is what you need and it works great all the time. just simple and cheap. you could probably make it cheaper if you want.

  I have the keyer Palstar makes and am real happy with it. It is a plug & play. Best feature for me at least is the variable pitch and variable volume side-tone. It is switch-able for grid-block as well as cathode keying. Battery or wall-wart pwrd.
I'm using mine with a straight key just so I can have the side-tone on my BA rigs. Had it on a DX-35 and a couple of Johnsons Ranger and Challengers. Great USA made product.  73

FWIW I have used the Winkeyer USB-HV with my DX-100.

Hammarlund made a keyer called the HK-1B back in the early 1960s while I was on active Navy duty.  It was relay operated, and unfortunately the keying voltage on some of the Navy's transmitters was well above the relay ratings.  I used one at our ham station which used commercial amateur gear and completely independent from the ship's comms.  It was hypnotic, watching those tiny relays dance!
