Allen-Bradley 800TC-H3216A Locking Cylinder With Key

The Allen‑Bradley 800TC-H3216A is a 30 mm selector switch with a locking cylinder and key, designed for secure operator control in panel installations as part of Rockwell Automation’s 800T/800TC family. It uses a keyed cylinder lock with a removable key and provides locking in selected operator positions to prevent unintended actuation. Key-code customization is available for 800T/800TC keyed cylinder configurations, with options configured via the optional cylinder lock key code (for example, the design supports codes such as 04). Some related 800TC variants, including 800TC-H32A, specify a standard key code (D018) for the operator lock, illustrating consistent keying across the line. This model is described by distributors as a 30 mm, finger‑safe selector switch suitable for panel mounting and automation applications where locking is required to control mode or function. Common applications include panel‑mounted control and mode selection in automation systems, Run/Stop or process configuration selections where operator access must be secured.
