The Multiquip 1742263700 Key Starter Switch DCA40SSKU4i is a genuine OEM ignition switch designed for the DCA40SSKU4i ultra-silent diesel generator. As a direct Multiquip OEM component, this switch is built to the same specification as the original unit — ensuring the correct electrical contacts, key cylinder fitment, and switching positions that the DCA40SSKU4i control panel requires. If your generator is experiencing ignition faults, a failure to crank, or an unresponsive start circuit, replacing the key starter switch with part 1742263700 restores proper starting system function right away.
Key Features
- Correct Contact Configuration — Matches the original multi-position switching circuit of the DCA40SSKU4i, ensuring start, run, and stop positions engage precisely as designed.
- Genuine OEM Component — Sourced directly from Multiquip, this part carries the same electrical ratings and terminal layout as the factory-installed unit on the DCA40SSKU4i generator.
- Direct Panel Fit — Designed to drop into the existing control panel cutout on the DCA40SSKU4i without rework, using the original mounting hardware and wiring harness connectors.
- Restores Full Starting System Control — A worn or failed key switch can prevent the generator from cranking or cause unintended shutdowns; replacing it with 1742263700 brings the start circuit back to proper operation.
- Electrical Safety Compliance — As a generator ignition component, using the correct OEM-rated switch maintains proper current handling and prevents overload risk at the control panel.
The key starter switch is the primary operator control for the generator's ignition and engine management circuit. When the key is turned, it completes or interrupts electrical paths that signal the engine to crank, run, or shut down — making it one of the most frequently used components on any generator control panel. A switch that has worn internal contacts, a damaged cylinder, or a faulty position detent can result in hard starting, unexpected shutoffs, or a complete failure to energize the start circuit. Replacing a failed switch promptly keeps the generator ready to power when it's needed most.
