Yes, that is it.

Here is a photograph of the actual part -

I replaced the 98 model's switch a couple of years ago with an Intermotor. The 98 is my daughter's daily driver. She had an unexplained starting issue one day like the battery had died. So I decided the replace the switch since its not an uncommon failure item. No further problems with the new switch. I understand the switch works on other Nissan models. Don't be surprised if the new one has a tighter fit due to a new cable length. Not much price difference between Intermotor and OEM. I usually go with Intermotor, for select parts that I know, to get a better warranty and local exchange. Here's a picture of old and new switches below.



I stated moving from from Advance batteries to Interstate. I'm growing tired of 36 month replacement warranty batteries that are "programmed to fail" at 39 months.
