Power switch cable for ZX Spectrum with LED

Inline switch cable, fits between the UK1400 PSU and Spectrum power socket
Saves wear and tear and tedious insert/remove cycles.
Green LED, useful as the Spectrum16/48 has no power indicator
Good quality 20AWG cable.
2.1mm pin / 5.5mm outer diameter socket and plug
Correctly switches the positive supply - most generic cables will switch the negative side because of the unusual polarity used by the Spectrum
Suitable for Spectrum 16 / 48/ 128 Toastrack and 128 +2 (Grey case model)
Please note: A few early Spectrum PSUs have a 5.00mm diameter plug -this will be too loose for the socket on this cable. It's quite difficult to judge by eye, but you can refer to this diagram for assistance.
