IP Rating Info Sheet
It’s a quantified measurement of a given switch’s ingress protection. The IP rating will tell you how “waterproof” a switch is and how resistant it is to the ingress of dust.
What is an IP Rating?

How do manual battery disconnect switches work?
Sometimes, items such as solenoids and illuminated switches must be used at the rated current and voltage due to the internal components. Ignition, push-pull, momentary, door and other types of non-illuminated switches can be used in a 24V system, with one provision. For a 24V application, you must de-rate the current capability of a 12V product.
De-rating: using Ohm's Law, if you double the voltage, you must divide the current in half. For example, if you have a 12V, 20A product, you can use it in a 24V, 10A system. You cannot use lighted switches at different voltages than those specified.

Although some manual battery disconnect switches are push-button emergency cutoff switches, in most cases, manual battery disconnect switches are rotary switches with lever, handle, key, or knob actuators. They may be single-pole, single-throw (SPST) switches for simple on/off functionality, dual-pole, single-throw (DPST) switches, or even single-pole, triple-throw (SP3T) battery selector switches for vehicles that use an auxiliary battery.

A switch with a higher rating will have more expensive internal components (bronze, copper, silver, and sometimes gold). Therefore, the cost is higher. Always select a switch that meets or slightly exceeds your needs. Failure to do so could lead to you paying for extra capability that you don't need or you ending up with a switch that fails because it doesn't meet your specifications. Cole Hersee offers a broad range of switches in different current ratings to allow you to buy the product that best suits your needs at the best price.
Two switches in the Catalog look identical, but one has a higher current rating and costs more. Why?
