[Amps] re Marsland stepper switch

[Fern Rivard]

    I wonder is anyone may have the specs on a Marsland RS612-R7, 152-673 switch. It is a stepper type of switch which has 5 ceramic gangs and 12 positions on each. It is a ceramic on these 5 gangs which looks like it can easily handle 2 kw. I suspect that it should operate on 24 volts dc but it will step over with only 12 volts dc @ 4 amps. I've had this in one of my goodies box for many years and think that it would be greater for use in either a multiband hf linear or in some form of antenna tuner set up but would sure like to get some information on it first. Yes, I did try a google search on it without any results.

    Any help would be greatly appreciated.  73 from Fern   VE7GZ
