Blue Sea Systems Black ON-OFF Battery Switch with locking key operation
p/n: BSS-6004200
This switch can be locked in the off position with the aid of a small padlock (not included)  This might lead it to be used for things such as golf carts or in systems where a service lockout is required. As a service lockout it could be locked with a wiretie. This Mini Battery Switch is also suitable for smaller boats such as center consoles or runabouts. The rating of the switch is almost as high as the e-Series switches but its compact size makes it more suitable for smaller boats. If you are installing this with large battery cables such as 2/0 awg and above you will find it easier to use the bigger switch if space is available. However if you want to use the maximum rating the switch allows you have to use 4/0 cables to meet its rating.  This is because the cables help to remove any excess heat.
