Abstract: In a spring-loaded retractile cord arrangement for an electrical appliance or telephone handset, a magnetically actuated catch mechanism is employed to arrest the cord at any preselected position without requiring the user to work against spring tension while holding the cord in that preselected position. Inadvertent locking during the rewind cycle is prevented by inhibiting the latch mechanism with a cam arrangement.
