Editing RAFI RS 76 M (diode) (section)

==Design==
Unlike most if not every other switch type that supports an internal diode, RS 76 M has only two legs. The stationary contact is attached directly onto one of the diode legs, and the other leg of the diode is used as a terminal.

The diode is therefore non-optional: it is part of the switch mechanism itself. The internals of the switch are quite different to that of the non-diode switch. The base of the switch does not secure the diode: the lid of the switch includes a block that rests on the diode and holds it in place. The movable contact is also not secured by the base, and appears to also be held in place by the lid.

The stationary contact is minute, measuring a mere 1.7 × 2.6 × 0.9 mm.
