I have a Batman Forever. Still working out the bugs with my batcave - damn switches are temperamental.
I have the same delays with the switches in the batcave - 60, 61, 62. Not sure sure about the 44, 45, 46 but I'm guessing it's the same as yours.
I believe this is by design. You don't want the switches in the batcave going off especially Lock 3 and Lock 2 as the first ball passes those to get to the Lock 1 position. For it to be Locked, it needs to close the switch for about a second. The first time I was working on the batcave switches, I thought something was wrong too.
