Allen-Bradley Guardmaster 440T-MSSSE23JJ Code JJ Single Standard Key Code Labeling Trapped Key Interlock Switch
Slamlock™ trapped key interlock switches combine the features of trapped keys with tongue actuated interlocks. When the actuator is inserted into the interlock (guard closed), the trapped key can be rotated and removed. With the key-free, the actuator cannot be removed. This locks the guard door. The trapped key must be re-inserted and rotated 90 deg to unlock the guard door. Slamlock™ interlock switches are available in mechanical, electrical and solenoid versions.
