Isolation Switch

The MacLean Isolation Switch acts as an access point used in marker posts and underground vaults. The switch is a safe and secure location to attach a ground wire and up to 5 tracer wires. Rotating the switch allows an operator to toggle between a fully grounded system and a status where all the tracer wires are isolated. Color coded terminals allow for secure and easy to identify directional attachment points for tracing equipment.
