Innospo Rotary Battery Disconnect Switch, 12–24V DC, 200A

Take Control of Your Battery Power

The Innospo 200A Battery Disconnect Switch brings manual power control to compatible 12V and 24V DC systems. Built around a raised red rotary knob and black housing, this model supports dual-battery switching and is suited to battery management in boats, RVs and vehicles.

Use it to isolate circuits connected through the switch when your setup is parked or being prepared for service. The kit includes copper cable lugs, heat-shrink sleeves, mounting bolts and a hex key to support installation.

Key Features

• 12–24V DC compatibility: For compatible 12V or 24V battery circuits. This switch does not convert voltage.
• 200A specification: Choose wiring, circuit protection and connected equipment to suit your installation. Verify continuous-duty and starting-load requirements before use.
• Dual-battery switching: Supports switching between two batteries in a correctly configured system. Follow the terminal markings and the wiring instructions for the supplied unit.
• Manual battery isolation: Disconnect power to circuits routed through the switch when required; independently connected loads remain powered.
• Easy-to-identify rotary knob: A raised red control makes the manual switch easy to locate, with a black housing and recessed mounting points.
• Connection accessories included: Four copper cable lugs, four mounting bolts, four heat-shrink sleeves and one hex key accompany the switch.

Made for Your DC Power Setup

Frequently Asked Questions

Does it work with both 12V and 24V systems?

Yes, the supplied specification is 12–24V DC. Use it within a compatible system; it does not turn 12V into 24V.

Can I use it with two batteries?

The supplier confirms support for dual-battery switching. Have the terminal configuration and switch positions checked against the supplied unit before wiring.

Is this an automatic circuit breaker?

No automatic overcurrent trip function is specified. This is a manual battery switch and does not replace the correctly rated fuse or circuit breaker required by your installation.

Will it disconnect every load on my battery?

Only circuits routed through the switch are isolated. Equipment connected directly to the battery or through another supply path can remain powered.

Can I install it on a boat or RV?

It is intended for compatible boat, RV and vehicle DC power setups. Select a protected mounting location and confirm the electrical load, cable size and terminal fit before installation.

Can I switch it while an engine or charging system is running?

Do not assume it is safe to disconnect a running engine or active charging system. Follow the switch, engine and charging-equipment instructions before operating it.

Are cables and batteries included?

No. The kit includes the switch and the listed connection and mounting accessories. Select compatible cables and batteries separately.

Installation: Have a qualified installer verify the wiring arrangement and load requirements. The 200A specification alone does not establish a continuous-duty duration or engine-cranking rating.
