When I observed relay closure with a 'scope in my Fig. 7 speedup circuit,
there was virtually no difference between these two relays. // The
person who extolled the virtues of the HC-1 claimed 2mS closure at 36v.
In my opinion, this is only possible with a lot more volts than 36. .
0.3H is not unlike molassas in January.
