Thetford Reed Switch Housing Assembly - C402C Cassette Toilet

This is Thetford's reed switch housing assembly used on the C402C electric cassette toilet. The reed switch is a small magnetically-triggered sensor housed in this bracket, forming part of the toilet's electric flush and level detection circuit, a common point of failure when the electric flush stops responding correctly or works intermittently. It is supplied as a complete housing assembly rather than a bare switch, for a straightforward like-for-like swap.

• Application: Thetford C402C electric cassette toilet
• Type: Reed switch housing assembly
• Function: Level/position sensing for the electric flush circuit

• Q: What symptoms suggest a failed reed switch?
  A: An electric flush that does not respond, cycles erratically, or stops partway through a flush can point to a faulty reed switch in this housing.
• Q: Does this fit other Thetford cassette toilets like the C200 or C250?
  A: No, this specific housing (3231662) is for the C402C model; other cassette toilets use their own reed switch parts, such as part 50716 for the C250.
• Q: Is this a genuine Thetford part or aftermarket?
  A: It is a genuine Thetford OEM part, also referenced by its earlier part number 32316.

  A: It involves accessing the toilet's electrical components, so some confidence with 12V wiring is helpful; Thetford's service documentation covers the fitting steps.
