Description
Overview:
This Volvo/Terex Isolator Key is a non-genuine replacement designed to operate the battery isolator/master switch on construction and garden machinery. Moulded from durable plastic in a high-visibility red finish, it is built to withstand daily use on site or in the workshop. The key engages the isolator switch to connect or disconnect the electrical circuit, helping to protect components, prevent battery drain, and support safe lock-out during maintenance. It replaces Volvo OEM No. 8157766 and suits a wide range of Volvo and Terex equipment such as excavators, wheel loaders, site dumpers, and similar plant. A practical spare to keep on hand, it restores functionality quickly when the original key is lost, worn, or damaged.
