Electric lock and key assembly

摘要

An electrical lock assembly which includes within a lock housing a set of flexible electrical key contacts and a set of electrical unlock contacts mounted in the lock housing and located proximate to the key contacts. A key directly engages the flexible key contacts and presses them directly against the unlock contacts thereby completing an electrical circuit between the key contacts and the unlock contacts. An unlock circuit means electrically connected to the unlock contacts is responsive to the completion of a circuit between the key contacts and the unlock contacts. In another embodiment the lock assembly includes flexible alarm contacts which are pressed against a second set of alarm contacts to activate an alarm circuit when an improper key is employed.
