Medeco® 3/4" diameter, high security switch locks offer a wide range of electrical functions with the physical security and patented key control of a Medeco cylinder. Available in either single or double switch models, Medeco switch locks are ideally suited for applications requiring controlled access to electrically activated systems, including alarms, ATMs, time delay safes, encryption devices, heavy power equipment, control panels, and electrically accessed doors and gates. Switch locks use a five pin cylinder to maximize keyed different and master keying capabilities. Medeco design and engineering resources are available to assist customers with special functional requirements.

The Medeco3 unique design provides triple locking action, making the locks virtually pick proof. All Medeco3 keys and locks are protected under patent, trademark, and copyright laws. Medeco3 keys may only be duplicated by Medeco or by an authorized Medeco Service Center, and only at your request.
