Description

This 440K-B04026 guard locking switch is positive mode and thumbwheel operated, and is ideally suited for use with simple machines which have short, constant run-down times due to the 20 second delay before the guard door can be opened. It is important that the unit is installed and operated correctly to ensure that the retractable shaft is not extended when the guard is open.
