Lifespan of Electrical Switches Mounted on Console Surface

I have an OEM electrical panel with rocker switches on my 1999 Boston Whaler JUSTICE 24, Boston Whaler part number 36-c825-00. What can I expect for lifespan of this style switch?
All seem functional now, but I am currently redoing the entire wiring harness, so it would be much easier to swap in a new switch cluster now than later. Can they last another 10 years?

Those are Contura style switches. I see no reason why they will not last a long time. If one does fail, it can be pulled out and replaced easily. Just two clips holding it in the panel.
If you decide you need a different type (single on/off - to on-off-auto) or one with a light, just swap the switch out.

The lifespan of electrical equipment like a switch is dependent on many factors, including:
--the number of times the switch is operated;
--the current load the switch is interrupting;
--the nature of the load, particularly inductive loads like motors where the interrupt current can be very high;
--the rating of the switch as originally manufactured with regard to number of cycles, load current, and overall quality;
--the environment the switch is placed in.
A low quality switch in a harsh environment frequently interrupting an inductive load near its maximum rating with the switch subject to a lot of weather, sunlight, rain, water, and other environmental influences, will fail much sooner than a high quality switch, seldom operated, interrupting a resistive load much less than its maximum rating, in a protected environment.
