Perko 8521DPC Compact Battery Selector Switch, Cup/Recessed Mount

The Perko 8521DPC Compact Dual Battery Selector Switch uses a cup-mount (recessed mount) design that encloses the switch behind a durable, easy open/close cover. The cover hides and protects the switch face. An installation hole size of 4" is required.

This battery switch lets you select between batteries or run both batteries combined in parallel for starting or charging. It can also serve as an emergency main disconnect switch in the event of an electrical problem.

Key Features:

• Cup-mount/recessed design with an easy open/close cover that protects the switch face
• Requires a 4" installation hole
• Make-before-break design
• Ignition protected
• Includes a removable key for extra security of the electrical system
• Four switch positions: Both Off, Both On, Battery 1 On/Battery 2 Off, and Battery 1 Off/Battery 2 On

A practical choice for dual battery setups that need flexible battery selection, parallel operation and a main disconnect in one compact switch.
