BATTERY SELECTOR SWITCHES

Ignition Protected

Standard features include a “make-before-break” design, for use with two or more batteries and single- or dual-engine systems.* They permit selection between batteries for staring and charging, or operation of both batteries in parallel. They allow the addition of an extra battery for use with accessories. The “OFF” position also acts as an emergency disconnect, in the event of an electrical problem. In addition, some models offer unique options, such as a keylock for additional theft protection.

Protected by the following U.S. patents: Design  260,637 – 4,280,028 – 4,424,424.
*For dual-engine systems, two switches are required.

Features

• Surface mount.
• Red plastic housing with large, black plastic knob.
• Improved design protects copper contacts and brass terminals used as electrical connection.
• For use with systems under 50 volts.

Capacity: 250 amps continuous, 360 amps intermittent

Description

Take a look inside a typical battery switch and you’ll find small, spring-loaded “line contacts” that provide the electrical gateway to your system. These line-contact designs provide a very small conductive area for high current flow, resulting in critical wear, carbon tracking and contact burns over time. At Guest, we understand the key to long, efficient switch life is large contact surface area.

That’s why Guest switches feature an innovative “sweep contact” design, which provides a large, flat surface area for maximum

conductivity and efficiency, without the excessive wear, carbon tracking and contact burns of inferior line-contact designs. All Guest battery switches safely provide positive battery disconnect, isolate all circuits and conform to U.S.C.G. safety standard 183.410 for ignition protection.

Guest Battery Switches Features

• Heavy-duty copper sweep contacts.
• Positive click-stop on all positions.
• Built-in skirt protects connections.
• “Make before break” contacts allow selection of all positions except “off” while engine is running.
• Alternator Field Disconnect (AFD) models allow selection of any position, including “off”, without damage to alternator or electrical system.
• For 6, 12, 24 and 32 volt systems.
• Marine UL Listed.
• Momentary ratings are for five minutes continuous.
• 1-year limited warranty.

Guest ‘Sweep’ Contacts Are Just Better

Guest’s smooth, flat “sweep” contacts provide up to 60% more contact area than inferior line-contact designs. Our contacts are “machined” to guarantee an electrically sound path, while line-contact designs suffer from a lack of matched contact surfaces, leading to arcing and excessive carbon tracking. Guest contacts also provide a unique, self-cleaning sweep every time the switch is used, maintaining a matched contact area for maximum efficiency and long life.
