Trapped key systems use a series of mechanical locks and keys to control the access of gates or doors to running equipment or machines, ensuring safe access. Solenoid locking gate sets, available with one to five gate switch modules, afford maximum protection by adding electrical interlocking, and can be configured in series or parallel arrangements.
