Multiquip 956-3127 Cole Hersee Ignition Switch

The Multiquip 956-3127 Cole Hersee Ignition Switch is a genuine OEM component designed for the DCA-25 ultra-silent generator series. Sourced directly from Multiquip, this switch meets the original design specifications for the DCA-25, ensuring correct fit and dependable operation. If your generator is failing to start, cycling erratically, or showing ignition circuit faults, the ignition switch is a common service point worth inspecting first. DHS Equipment stocks this genuine OEM part ready to ship so you can get your DCA-25 back online without delay.

Key Features

• Genuine OEM Electrical Specification — Matches the original Cole Hersee switch spec for correct circuit resistance and contact rating, not a generic substitute.
• Direct-Swap Installation — Designed to connect to the existing wiring harness on the DCA-25 with no splicing or adapter wiring required.
• Confirmed DCA-25 Fitment — Verified for the DCA-25 ultra-silent generator series; use part number 956-3127 to confirm compatibility before ordering.
• Protects the Starting Circuit — A correctly functioning ignition switch ensures clean start and stop signals reach the engine control system, preventing unintended cranking or shutdown faults.
• Electrical Safety Compliance — As a primary ignition control component, using the correct OEM-spec switch is essential for safe generator start/stop operation on a live electrical system.

The ignition switch is the operator's primary interface with the generator's starting and stopping circuit. When the key is turned, the switch sends the appropriate electrical signal to the engine control module to initiate cranking, run the machine, or trigger a controlled shutdown. A worn or failed ignition switch can cause hard-start conditions, intermittent shutdowns, or a complete loss of ignition response — all of which take a generator out of service at the worst possible time. Replacing a faulty switch with the correct OEM-spec part restores clean, predictable ignition control and eliminates the risk of ghost faults caused by poor contact quality.
