The Multiquip EM97028 Ignition Switch With Key is a genuine OEM component designed for ST-45HRM and ST-70 submersible pumps. As a direct OEM replacement, this switch is sourced to the original specification, ensuring the correct electrical connections, key profile, and switching action for these units. Confirmed fitment for ST-45HRM and ST-70 models makes part selection straightforward — no guesswork on compatibility. Order EM97028 to restore full electrical control to your pump with a part built to the same standard as what came on the machine.
Key Features
- Genuine OEM Electrical Spec — Matched to the original switching resistance and contact configuration, so the ignition circuit operates exactly as engineered for these pumps.
- Correct Key Profile — Ships with the matching key, so the lock cylinder and key cut are ready to use right out of the box without sourcing additional hardware.
- Confirmed Fitment — Verified for ST-45HRM and ST-70 submersible pump models; use part number EM97028 to confirm your application before ordering.
- Restores Full Start/Stop Control — A worn or failed ignition switch can prevent the pump from starting, cause intermittent shutdowns, or leave the circuit in an uncontrolled state; this replacement brings back clean, consistent switching.
- Electrical Safety Integrity — A properly functioning ignition switch is a critical control point in the pump's electrical system; using an OEM-spec replacement maintains the circuit protection and insulation ratings the system was designed around.
The ignition switch is the primary operator control that opens and closes the electrical circuit powering the pump's motor. When the switch is turned to the run position, it completes the circuit and allows current to flow to the motor; when switched off, it breaks the circuit and stops the unit. A failing ignition switch can cause hard-start conditions, unexpected shutdowns mid-operation, or a complete loss of electrical control — all of which disrupt dewatering or transfer operations and can leave a site without a functioning pump when it's needed most.
