Blue Sea 7701 ML-Series Solenoid with Contura Switch

The Blue Sea 7701 ML-Series Solenoid delivers a 500 amp continuous rating for use as a remote battery switch on inboard gasoline or diesel engines, paired with a Contura rocker switch for on/off control. It is designed for boaters who want to shorten long battery cable runs by mounting the solenoid right at the battery instead of at the helm.

The magnetic latch only draws current while changing state, drawing none in the steady ON or OFF position, and silver alloy contacts provide high reliability switching live loads. An optional manual switch adds a level of safety, letting you control the switch with or without power and offering lockout capability for servicing.
