This redesign was done with the aim of improving the usability of a standard three pin plug for an elderly or infirm person. The final design had many novel features which could aid the user:
- Moulded loop handle integrated into the casing.
- Lock nuts used to attach cable clamp.
- Improved labelling and wire channel design.
- Colour coded push-fit wire clamps.
- Quick release casing once unplugged.
