The Telsitine High Current Master Battery Switch, 12V-48V Heavy Duty Battery Isolator Switch with Face Plate, 300A Waterproof Marine Battery Cut/Shut Off Switch for RV Marine Boat Vehicle Truckseems good quality and well made.I fully believe it is waterproof based on its construction.Gives a vary solid on / off feeling when actuating the lever.I just wish the max current and voltage were labeled on the switch itself.The studs measured right around 3/8" / 10mm as advertised.It's got a good heft and feels quality but without knowing what's inside only time will tell how it holds up.At ~$21 at the time of this review it appears you get a good quality switch.

Telsitine High Current Master Battery Switch, 12V-48V.Solidly built heavy duty switch. Sealed main body of the unit is advertised as water resistant, which I believe. Impressive high current (300A) continuous duty makes it a great choice for your switch option. It's indiscriminate to your DC voltage choice options between 12-48 V.Wide variety of applications is another benefit of purchasing this switch.

Good and heavy, should stand up to my switch killing, battery draining truck. Won’t know until later how it holds up.

This is a very useful master battery switch that can withstand the high current loads during engine starting.Rated at 300 amps, it should be suitable for many marine, automotive, and maybe some light truck loads, but you naturally want to check the normal starting loads, particularly for trucks, before you install this.These days almost every piece of aftermarket electronics seems to have a parasitic current draw when turned off. This means that you have to have a master battery switch installed to prevent a dead battery, especially for vehicles that sit idle for long periods of time.This switch is simple to install and easy to operate.

This is a very well made master battery switch.It's a switch leaves no question if it is on or off. It is a little bit bigger than I expected, but that is not a problem.

This is perfect for a battery disconnect. It has a solid mechanical action and given it is rated for 12-48V, even with max amps of 300amps you aren't likely to see much arcing.The switch is strong and sturdy. It is waterproof, but feels more splash proof than submergible.I installed mine in a bracket on a tractor to disconnect my battery when not in use. This will prevent unwanted drain and allow the battery tender to only tend to the battery and not app the vampire draws that exist in the old wiring.For $20 this is an excellent value and is easier than disconnecting the battery after every use.
