Multiquip 11078 Ignition Keyset

The Multiquip 11078 Ignition Keyset is a genuine OEM replacement designed for a wide range of Multiquip and affiliated-brand equipment, including Essick stationary mixers, Mayco concrete pumps, Whiteman power buggies, ride-on trowels, and asphalt rollers. As a direct OEM replacement, the 11078 is sourced and validated to match the original ignition hardware installed at the factory, so you get the correct key profile and switch interface without guesswork. Confirmed fitment includes the PRO12, PRO12E51, PRO12E53, C30HDG, C30HDGA, C30HDN, C30HDNI, WBH-16, WBH-16E, WBH-16EF, WBH-16F, AR13HA/HAR, HHN31V, HHN34TVD, and HTN and JTO series trowels. DHS Equipment supplies this part direct, so you can trust you are ordering the right component for your machine.

Key Features

• Genuine OEM Ignition Interface — Matches the original key profile and tumbler specification, ensuring correct engagement with the ignition switch as built.
• Cross-Equipment Compatibility — A single keyset covering Essick PRO12 mixers, Mayco C30HD concrete pumps, WBH-16 power buggies, AR13 rollers, and HHN/HTN/JTO ride-on trowels.
• Drop-In Installation — Designed to seat and function in the existing ignition housing with no modification to the switch assembly or mounting hardware.
• Consistent Start-Up Security — A worn or mismatched keyset can cause intermittent starting failures or prevent the machine from running altogether; the 11078 restores reliable ignition operation.
• Electrical Safety Compliance — Correct key-to-switch fitment maintains the integrity of the ignition circuit, preventing unintended energizing of the starter and supporting safe machine shutdown procedures.

The ignition keyset is the mechanical interface between the operator and the machine's ignition circuit. When the key is inserted and turned, it completes or interrupts the electrical path that controls the starter motor and main power circuit, allowing the engine to start and stop as intended. A worn, damaged, or incorrect keyset can cause the ignition switch to stick, fail to engage, or allow the circuit to remain live when it should be off — all of which create both operational and safety problems. Replacing the keyset with the correct OEM part restores full control over the ignition system and ensures the machine starts and stops predictably every time.
