The Dyson power switch shown here is for use with the DC33, DC40 or DC41 upright vacuum cleaners. This is the internal switch that works with the power button (actuator) seen on the outer portion of the vacuum cleaner unit. On all three vacuum models, this switch is installed on the duct assembly.
On the DC40 & DC41 vacuums this switch is also used for the brushbar power, but is not the same as the brushbar reset switch.
