Abstract:
An electrical switch for switching on and off an electrical appliance comprising:a body,a fixed contact and a movable contact,an actuator supported by the body for pivotal movement, causing movement of the movable contact between a switched-on position and a switched-off position, wherein the actuator has an external part for manual operation, and an internal part for causing movement of the movable contact, and an intermediate part about which the actuator is hinged to the body,a first internal spring engaging the internal part of the actuator and acting upon the actuator, the first internal spring extending generally in-line with the actuator, in compression, such that the actuator and spring are pivotable simultaneously in opposite directions through an over-centre action about an unstable central position, anda second internal spring incorporated in the internal part and bearing on one side of the internal part for holding the movable contact in the switched-on position when the internal part is initially departing from a first of a pair of opposed parts until an opposite side of the internal part impacts a second of the pair of opposed parts, whereby a sound is produced indicative of the movable contact reaching the switched-off position.
