Old Electrical Equipment - MK Socket Outlets
Several double socket outlets made by MK.
Double unswitched outlet
Double outlet, no switches. Two fixing holes.
Single oval MK logo at the centre of the plate.
The outlets are not vertically centred on the plate - they are positioned towards the top, leaving a much larger space under the live/neutral holes.
Double switched outlet A
Double outlet with centre switches. Oval MK logo at the centre of each outlet. Moulded 'ON' and 'OFF' detail above and below each switch.
Two fixing holes, same spacing as modern outlets.
The outlets are vertically centred on the plate.
This example has signs of overheating on the left outlet - the hole for the live plug pin is discoloured. This was probably due to a plug with a loose connection, causing the plug pin to heat up when in use.
Double switched outlet B
Double outlet with centre switches. Round MK logo at the centre of each outlet.
Four fixing holes. This will not fit onto modern boxes, as they have fixings at the sides. Boxes of the same age as this outlet typically had 6 fixings - two on each longer edge, and one on each shorter edge.
