Locks a power operated switch

Restricts the use of a hand operated switch or derail

An Electric Switch Lock is primarily designed to restrict the use of a hand-operated switch or derail. This mechanism enhances safety by ensuring that only authorized personnel can operate the switch or derail, which helps to prevent unintended train movements that could lead to accidents or derailments. By providing a locking function, it ensures that the switch remains in a specific position unless it is specifically permitted to be changed, often requiring certain conditions to be met or the presence of a responsible operator.

In the context of operations, this is critical for maintaining the integrity of the rail network, especially in areas where hand-operated switches are used regularly. The switch lock is crucial in signaling the operational status and limiting access to ensure the appropriate protocols are followed when changing switch positions.
