241-8368 (2418368) — 24V / 100A (Magnetic Switch Relay / Switch GP-Magnetic). Specifically designed for high-current circuits—such as starter motors and main power systems—it features an integrated metal heat sink and a Deutsch waterproof connector. I. Core Specifications

Part Number: 241-8368 / 2418368

Type: High-Power Magnetic Starter Relay / Power Switch

Coil Voltage: 24V DC

Contact Capacity: 100A (High Current)

Physical Features: Includes aluminum heat sink, two large bolt terminals, and one wiring harness with a Deutsch 2-pin waterproof connector

Mounting: Dual-bolt fixation, includes ground terminal

Function: Uses a low-current signal (from the ignition switch) to control a 100A-class starter motor or main power circuit; prevents voltage drop and protects the ignition switch from burnout
