Abstract
A component (10) of a device, such as a keypad mechanism (10) of a cash dispenser, is provided with a mechanism for detecting separation of the component from another part (16) of the device, for example a front panel (16) of the cash dispenser. The mechanism includes a member (64) moveable between first and second positions, and biasing means (34) to bias the member resiliently in the first position. In use, the member (64) is forced into the second position by contact with the part (16). If the component (10) and the part (16) are separated, the member (64) moves from the second position to the first position. The mechanism also includes a signal means to provide a warning signal when the member (64) moves to the first position. A tube (50) of ceramic material or other hard material is provided to resist ingress of a drill bit to the member (64).
