l
Although the product ranges mentioned aim to meet the design considerations for Part M compliance, Crabtree
would be prepared to discuss any future development on a project by project basis and assist, where possible,
with any other requirements.
Operation
Light switches, which are to be used by the general
public are encouraged to have large rockers at a
height corresponding to the door handle, within the
900 - 1100mm range.
This would enable people with a physical disability or
visual impairment to both locate and activate them
easily.
The Crabtree range of electrical wiring accessories all
come with a large concave rocker, with the ‘Corinthian’
range having an extra wide rocker.
Freedom from obstruction
Light switches and controls should be ‘well separated’
or activated by a large push pad to prevent
inadvertent operation.
The operation of switches, outlets and controls does
not require the simultaneous use of both hands,
except where this mode of operation is necessary for
safety reasons.
Where several switches on panels are required.
In addition the Crabtree Rockergrid range provides a
wide choice of switch options.
