<p>This invention relates to magnetically operated locks. In prior art magnetically operated locks when a key containing a magnet is placed on the enclosure, the arm is lifted from the locking tab and the magnet in the key is then moved to pivot the locking arm. This arrangement is relatively expensive and may be operated by unauthorized personnel. Other magnetically operated locks often require key magnets arranged to both attract and repel corresponding locking elements. The arrangement of locking elements for both attractive and repelling movement contributes to the expense of magnetically operated locks while the use of an access opening often enables the purpose of the lock to be frustrated. The present invention provides a magnetically operated lock for a coaxial switch in which a slide member is operated in opposite directions by a slide magnet in a key to connect an incoming coax line to either another coax line or to ground. The key has a configuration corresponding to the lock housing and when associated with the lock housing, automatically positions a plurality of spaced magnets in the key to operate a plurality of pins in opposite directions to unlock the slide. Removal or disengagement of the key from the lock housing enables the pins in the lock to engage the slide and lock the switch in either position to which it is operated.</p> |
