There was a problem filtering reviews right now. Please try again later.
Regarding my specific setup: I have a standard marine battery running to a 120hp Yamaha outboard. For the last couple seasons I have had an issue with the battery dying if I didn't use the boat for several weeks. Physically disconnecting the battery terminals after using the boat solved the problem, but it wasn't the most user-friendly solution for the rest of the family. The issue suggests a larger trickle from the battery than there should be, but it's not worth my time or money to figure out what device is pulling current even when the key is off. So the solution was to get a simple switch that does the same thing as physically disconnecting from the terminals. It's worked great so far; no battery drain after leaving the boat for a month.
Originally I intended to mount it below the dashboard, but I ended up taking more simple route and mounted it closer to the battery in one of the compartments under a back seat. I used a 3 5/8" hole saw to cut through the plastic wall of the seat, about halfway up from the floor. Then I pushed the switch into the hole, marked the four locations of the bolts, drilled four small holes, and mounted the switch with four nuts and bolts.
NOTE, I needed the following extra materials to install the switch:
1. 3 5/8" hole saw (not needed unless flush-mounting, and you could use a different tool too)
2. Four bolts and nuts (at least 3.5" in length, I forget the diameter)
3. Wire and crimp-connectors to extend the wire from the battery to where I mounted the switch, remember that you only need to extend the positive (+) cable to the switch)

デザインもよく、使い勝手が良い物です。
外観を一切変更せず、私の独自の方法で、接触抵抗を85%低減できました。
このため、発熱が低減できます。
非常時やメンテ時のみ使用する場合には問題ありませんが、頻繁に使用する時は、電極構造を変える必要があります。
