Salvo?

I completely agree with your summary, and the manner in which SH3 fires all salvoed torpedoes at once is completely wrong, but in fact the Germans did indeed have a Salvo selector switch, and it provided automatic firing of the selected torpedoes.

86. In salvo firing No. 1 selector switch is set to "salvoes" No. 2 to the particular combination of tubes to be fired. On pressing the firing pistol the first torpedo is fired and an automatic timing relay is energised which fires the remainder in succession with the minimum firing interval. This interval is stated to be 3 seconds, but it is known that later instructions have been issued that the firing interval is to be not less than 8 seconds.

I never use it myself, and always take at least five seconds between torpedoes.
