Query: Nice router, bad switch

I've have a number of Bosch tools and they have all been good with the exception of 2 routers. One, the 1613 plunge router and this one, the 1617 plunge router/fixed base router kit. Both have bad switches. Both switches were replaced with new bad switches. Dust. How can a company that makes quality tools make routers with switches that are not dust proof? These routers were purchased 4-5 years apart. I thought that would be sufficient time to address the problem. Apparently not... No more Bosch routers for me.
