A switch 10 is disclosed comprising a housing 15,16 formed with a chamber 12 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 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 switch is used to hydraulically lock an excavator quick connector to ensure the bucket does not come loose during use. |
