Rotary Switch Lock

The Medeco® Rotary Switch Lock is designed for use with most brands of rotary switches, providing maximum versatility in systems requiring multiple switch functions.  Switch Locks are available with a variety of key withdrawals at either 45 degrees or 30 degree increments.  Positive stops are available to eliminate over-torquing of switch stops.  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 lcoks are protected under patent, trademark and copyright laws. Medeco3 keys may only be duplicated by Medeco® or by an authorized Medeco® dealer, and only at your request.
