MAGNETIC PROXIMITY SWITCH

摘要

A magnetically operated proximity device is provided with a pivotal armature formed as a hat in cross section with two L-shaped members, one being longer and greater in mass than the other. The horizontal leg of each L-shaped member is arranged such as to contact an electrical contact. The greater surface area of the L-shaped members enhance the sensitivity of the device, with the horizontal leg of each L-shaped member extending over a different pole face of a permanent magnet.
