There is a switch panels in the “couch” and apparently the switch marked “Read” - which turns on a reading light, is no longer working.

Disassembled the switch panel. The panel consists of a circuit board and 7 little “modules” which push into it with pin/tube connectors.

The switch panel has a short 10“ wire, then what looks like a RS232C Male connector.

There is a wide label stuck to the cable. It has this information on it:

CUST P/N: SPS-2-4-4567
S/N: 060100840

Etched into the gold metal on the switch panel is this information:

The switch is a small mechanical push switch plus a small circuit board.
