ABSTRACT:
A switch is disclosed comprising a housing formed with a chamber along which a ball can roll. An element having a pair of arms is pivotally mounted within the housing, with one arm either side of the ball, such that an inclination of the switch causes the ball 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. The chamber acts as a dump for hydraulic fluid from the hydraulic circuit.
