What is a Battery Switch and What are the Different Types?


A battery switch help controls total onboard power usage. They are used to connect or disconnect electrical devices from the electrical system. They help prevent battery discharge during periods of inactivity. Allow a quick and easy way to shut down the entire electrical system in case of emergency. An optional keypad lock helps prevent unauthorized use of the boat.


It is a security system that consists of a current battery switch, which when activated interrupts the electrical circuit and leaves it without voltage. It is presented in the form of a safety mushroom with or without a key, with a red rotary switch. This last mechanism is similar to a water tap, since when tightening it allows the connection, while when loosening it stops. The disconnector is placed on the positive pole to ensure that there is no voltage.


It is used in caravans to release the battery from the electrical circuit and connect the auxiliary input of alternating current. In machinery and cars it serves to avoid current leaks that drain the battery, as well as an additional anti-theft system. If two batteries are installed at the same time, this system separates them and gives a passage of current in case of an emergency.


In addition to doing everything a battery disconnect switch does, battery selectors allow battery selection (of two or more batteries) for specific purposes, including starting engines, running accessories or even recharging. They allow the use of one or more batteries in systems with one or more motors and make it easier to put the batteries in parallel for emergency starting when one or both batteries are substantially discharged.


Whether you're getting away from your car, boat, RV or farm machinery, or if you simply want to keep away potential thieves, a battery cut-off switch can come in handy. Disconnecting the battery when you are away from your vehicle for an extended period of time helps prevent the battery from running out. When it's necessary to reconnect, simply use the switch to reconnect the battery and you're ready to go.


Disconnecting the battery from cars with digital systems will erase the memory of clocks, radios and the computer, and may affect the operation of the car.


Different Types of Battery Switches


Actors: The actuators of the circuit-breakers can be normally open when the circuit is closed (the case of the buzzer) or normally closed when the circuit is opened.


Pushbuttons: Also called momentary switches. This type requires the operator to maintain pressure on the actuator so that the contacts are joined. An example of its use can be found in the bells of houses or apartments.


Double pole switch.: These are the number of individual circuits controlled by the switch. An example of a single pole switch is the one we use to light a lamp. There are 2 or more poles. For example, if we want to start a 220-volt motor and a 12-volt indicator light at the same time, we need a 2-pole switch, a pole for the 220-volt circuit and another pole for the 12-volt circuit.


A number of ways: It's the number of positions a switch has. Again, the example of a one-way switch is the one used to turn on a lamp: in one position it turns on the lamp while in the other it turns off.


Two-way switch.: There are 2 or more ways. An example of a 3-way switch is the one we would use to control a traffic light where a bulb of each color is lit for each position or way.


Combinations: The above three classes can be combined to create different types of switches. The following graphic shows an example of a DPDT switch.
