Fascia housings for Tortoise SPDT switches

I found a PVC fitting at Lowe's that I use as a housing for the SPDT switches.

Here are three mounted in the fascia.

Close-up of one assembly.

Here are the specs:
- Lowe's part # 251179
- Price $0.38 each
- 3/4" Fiting PVC PMSTR ADA
- Apollo 69BV)$)^PZ Cpvc Pipe Inlet/Outlet Pipe Adapter.

Since the inside has a full bore opening I made washers from styrene, bored a hole for the SPDT switche and glued the washer inside the Adapter.
