AN APPARATUS FOR INDICATING ACTUATION OR DE-ACTUATION OF A MAGNETICALLY ACTUATED DEVICE

摘要

An apparatus (100), provides an indication when a magnetically actuated device is actuated without affecting the device performance. The apparatus (100) comprises a magnet (110, 150), a guiding arrangement (120), and an indication unit (130, 155). The magnet (110, 150) is disposed on a plugnut (55) of an actuation unit (50) which actuates the device (52). A side (112, 152) of the magnet (110, 150) facing a side (57) of the plugnut (55) has same polarity as that of the side (57) of the plugnut (55). Due to same polarities, when the plugnut (55) is energized, the magnet (110, 150) is repelled by the plugnut (55). The indication unit (130, 155) identifies the displacement of the magnet (110, 150), and provides a visual indication to indicate actuation of the device (52).
