Multiquip 1823100080 Starter Switch

The Multiquip 1823100080 is a genuine OEM Starter Switch designed for the DCA series ultra-silent diesel generators, including the DCA25SSI, DCA25SSIU, DCA25SSAI, DCA25SSIU-GEER, DCA40SSI, DCA40SSAI, DCA45SSIU2, DCA45SSIU2-FEMA, DCA45SSIU2-GEER, DCA60SSI2, DCA60SSAI, and DCA25SSI2 models. As a direct Multiquip OEM component, the part meets the exact electrical specifications required for proper engine start and shutdown sequencing on these units. Sourced directly through authorized Multiquip distribution channels, this part is the correct choice when you need confidence in compatibility and function. DHS Equipment stocks this component to keep your generator service turnaround fast and straightforward.

Key Features

• OEM Electrical Specification — Matched to the precise switching resistance, contact rating, and circuit logic required by DCA series generator control systems.
• Drop-In Connector Compatibility — Designed to connect directly to the existing wiring harness on supported DCA models with no splicing or terminal modification.
• Broad DCA Series Coverage — Fits DCA25SSI, DCA25SSIU, DCA25SSAI, DCA40SSI, DCA40SSAI, DCA45SSIU2, DCA60SSI2, DCA60SSAI, and related variants including FEMA and GEER configurations.
• Dependable Start Sequencing — A correctly functioning starter switch ensures clean engine engagement and proper shutdown control; a worn or failed switch can cause no-start conditions or uncontrolled cranking.
• Electrical Safety Compliance — As a genuine OEM ignition-circuit component, this switch meets the original design intent for safe start and stop operation on diesel generator equipment.

The starter switch is the operator-facing control that initiates and completes the engine start and stop circuit on the generator. When the switch is activated, it closes the ignition circuit, signaling the starter motor to crank the engine and allowing fuel and spark timing systems to engage. Over time, internal contacts within the switch can wear, corrode, or fail to seat properly, resulting in intermittent starting, failure to crank, or an inability to shut the engine down cleanly — all of which can interrupt generator availability on critical jobsites.
