Marine batteries are connected to the trolling motors by the help of switches for better connection, and option of turning them off when you want. These switches are of great help in maintaining the connection, and protecting the batteries from draining due to unnecessary work. These switches cut connection of one battery, while other is on work, for charging. For that, you have to connect the batteries one by one to the switches. This is of great help when you want to immediately charge the low the battery.

Blue Sea Systems e-Series Selector Battery Switch
The main use of switches is to cut power, of all, or one battery, without cutting power. The design of make-before-break contact allows switching between batteries without disturbing the operation. Also the switch is security wise safe and sound, and made from best quality materials, the proof is CE Mark on the product. The switch is Ignition protected which ensures safe installation, when it could be really dangerous in the case of gasoline powered boats. The design of blue sea systems eseries selector battery switch case is unique and allows surface or rear panel mounting, according to the size of the boat and placing of the motor. It also meets American Boat and Yacht Council (ABYC) safety standards for battery switches. The switch has 3/8″-16 tin-plated copper studs for better conductivity and the alloy is corrosion resistant, accepts 3/8″ and M10 ring terminals. 7/8″ (22.22mm) stud length to accept multiple cable terminals. The special tactile textures indicate knob position by touching it only. The switch is red in color, and looks elegant while using. It is not only a looker, but also a great worker. Personally, I have found no problem in using this switch.
Marinco 701 Battery Disconnect Switch
This switch of battery disconnects the power connection very efficiently and without any fusss. It features a control knob which can’t be removed while the apparatus is working, i.e. in on/off position. The only way it can be removed is by switching to a counter-clockwise 45 degree position. One of the most fascinating feature is removable side plates on 4 sides for access of I/O cables. The rear cover insulates the rear terminals against by any malfunction. The Marinco 701 Battery Disconnect switch is considered very safe, and it meets ABYC requirements. The switch can be mounted on the surface of the boat or by cutting a 52 mm hole. The switch has 3/8″-16 tin-plated copper studs for better conductivity and the alloy is corrosion resistant, accepts 3/8″ and M10 ring terminals. 7/8″ (22.22mm) stud length to accept multiple cable terminals. The color combination looks really well, and the design is elegant enough to match your boat. The switch is very good in terms of every aspect, whether it is safety, performance or anything else. I would recommend this switch to every boat user, as it has everything one needs, I have personally used it, and found decent.
Perko 8501DP Marine Battery Selector Switch
The Perko 8501DP marine Battery Selector switch works perfectly between 50 volts capacity, 250 amps continuous and 360 amps intermittent. The main use of switches is to cut power of individual or all batteries, while simultaneously working. The design of make-before-break contact allows switching between batteries without disturbing the operation. Also the switch is security wise safe and sound, and made from best quality materials, the proof is CE Mark on the product. The switch is Ignition protected which ensures safe installation, when it could be really dangerous in the case of gasoline powered boats. The design of the case is unique and allows surface or rear panel mounting, according to the size of the boat and placing of the motor. It also meets American Boat and Yacht Council (ABYC) safety standards for battery switches. The switch has 3/8″-16 tin-plated copper studs for better conductivity and the alloy is corrosion resistant, accepts 3/8″ and M10 ring terminals. 7/8″ (22.22mm) stud length to accept multiple cable terminals. The special tactile textures indicate knob position by touching it only the switch looks elegant, and has standard features that every switch in this category has. But the way it works and represents itself is amazing. I would recommend it for change from mainstream.
How do Marine Battery Switch Works?
The basic function of switch is to cut the power or make the circuit depending upon which side it is connected. But marine switches are slightly different than normal switches. Whereas normal switches purely cuts the power, marine switches cut power of one battery, or another or all, depending upon the knob. This particular thing helps in switching the drained batteries, charging them, or connecting a new one.
All the batteries are connected to the switch, and switch has three positions(normally) 1,2, all and off. When the knob is on 1, the first battery is connected in the circuit, and all connections are broke. When the switch is at 2, the battery which is second in the circuit, is connected, all for all batteries and off is the totally incomplete circuit position. The secret of working lies in the wires which are connected to the switch. Each battery should be individually connected to the switch by wires. Then switch does the job of breaking the circuit. The procedure is real simple, just like normal switch, but has few modifications.
Benefits of Using Boat Battery Switches
There are many benefits of a switch; they’re integral part of the motor circuit. They play the role of completing the circuit and breaking it.
They protect the circuit from malfunctions like overheating, short circuit, fire and many more. Had there been the connection open, it would break by the short action of the force. So in a way, switch acts as a protector for the circuit.
The switch helps in changing the route of the current of one battery and another, depending upon the knob. Marin switches are designed to work simultaneously, while the power of one battery is cut down. This helps in replacing drain and old batteries.
Switch save the hustle and bustle of opening wire, and joining to another, when the battery gets low. You can simply shift the knob, and your job is done.
They help in preventing unnecessary power usage caused by the absence of a switch, as direct connection will keep the motor running.
They are comparatively safe, open wires can be dangerous, it can give mild electric shocks, which could divert your attention to something else
Switch is the part that you should have in your boat. It is among must haves.
How To Choose The Right Boat Battery Switch?
Choosing the right switch for your boat is art. There are so many varieties of switch in the market that you may need double check what you’re buying. There are some points that you should check while making the final decision.
If you’re using more than two batteries, than you need to get the switch with more number of knobs. Usually two batteries switch are used, but choice is always yours to increase them.
The hardness of the switch depends upon the plastic used, and if the case is made of industrial grade plastic, then it is a must go. Simple plastic can crack by simple accidents.
You should go for the switch which is highly durable, I mean; wear and tear should be less on heavy duty. These kind of switches are hard to find, but worth the hardwork. Pins should be made of high tensile alloys, for hardness and conductivity.
They’re important while looking for switch. Make sure they’re of high quality and durable enough.
Design of the switch should be great, it should be easily installed, and knob should twist in the right way. Else, you’re going to get some problems.
