Define the isolation duty
Confirm whether the switch is used for routine parking isolation, maintenance safety, emergency disconnection or body-equipment control. The application influences current duty, mounting and access requirements.
Compare electrical and mechanical details
Review continuous and short-duration current requirements with the nominal system voltage. Then compare terminal size, mounting dimensions, key or lever operation and environmental exposure.
12V or 24V system
Continuous and intermittent current
Terminal type and cable size
Panel or surface mounting
Key, lever or rotary operation
Confirm the exact order reference
Agree the switch model, accessories, labels and packaging before production. Battery switches that appear interchangeable can differ in terminal orientation and mounting footprint.
