Abstract
The invention provides a hand-operated interface through which a stairlift user can control the operation of the stairlift. The interface is configured for comfortable reception in the palm of the hand and its position may be adjusted along the axis of the armrest of the stairlift chair to best suit the arm length of the user. The interface may also incorporate an isolation switch which provides both a visual and a tactile indication of whether or not the stairlift controls are activated for use.
