How to Confirm This Is the Right Switch for You
Check your existing switch or your toilet's parts documentation for either part number 38645 or the older 36293 — these are the same component under Thetford's updated numbering system. This switch is designed for Tecma Silence Plus models specifically; if you have a different Tecma model (Silence Plus 2G, Elegance, Evolution, etc.), your control panel/switch may differ. If you're unsure which model you have, check your toilet's data plate or contact us for help confirming fitment.
Frequently Asked Questions
Is part #38645 the same as the old #36293?
Yes — Thetford updated the part number from 36293 to 38645. It's the same physical switch with no functional changes; if a parts diagram or old documentation references 36293, this is the correct current replacement.
Why does this switch need to be waterproof?
Marine and RV bathrooms are exposed to significantly more moisture than a typical household bathroom — splashing water, humidity, and cleaning products. A standard switch can corrode or short out over time in this environment, which is why Thetford builds this switch with sealed, waterproof rubber connectors specifically for these conditions.
Will this fit my Tecma Silence Plus 2G?
This switch is specified for the original Silence Plus line. The Silence Plus 2G uses different control panel options (such as the 2-button wall switch, part #36387) — check your specific model before ordering to ensure correct fitment.
My flush button feels spongy or doesn't respond consistently — is this the right fix?
Yes — a worn or water-damaged flush switch is one of the most common causes of inconsistent or unresponsive flush activation on Tecma Silence Plus toilets. This is a direct, affordable fix before assuming a larger electrical or control panel issue.
Is installation something I can do myself?
Yes — this is a straightforward wall-mounted switch replacement with waterproof connectors, typically requiring basic hand tools and no specialized plumbing or electrical expertise.
