<p>A switch (10) is disclosed comprising a housing (15) formed with a chamber (17) along which a ball (11) can roll. An element having a pair of arms (13) is pivotally mounted within the housing, with one arm either side of the ball, such that an inclination of the switch causes the ball (11) to move along the chamber and impinge on one arm of the element to correspondingly turn the element and change the operational state of the switch.
