UP Switch - Nussbaum - 85.23 — a direct-fit replacement electrical control component. Ordering the electrical control component from us gets you the OEM piece that matches the lift, not an aftermarket knock-off that is close but not the same.
Specifications
- Part number: ALS-7453-89
- Type: Genuine OEM electrical control component
The control gear — switch, contactor, overload, limit switches — is what makes the lift safe to operate, not just able to run. The button has to be hold-to-run so the lift stops when you let go; the overload has to trip before the motor cooks; the limit switch has to cut power at full height. When a control part fails, the risk isn't only a lift that won't work — it's a lift that won't stop when it should.
The electrical system feeds the motor, and the motor drives the pump — so an electrical fault often looks like a hydraulic one and vice versa. A lift that won't rise might be a dead capacitor, a burned contactor, a tripped limit switch, or a pump that's seized and stalling the motor. The wiring, the switch, the contactor, the motor, and the pump are one chain; trace it in order instead of guessing.

Replacing your electrical control component
Servicing the safety cutouts — limit switch, overhead shut-off, overload — is about confirming the lift stops on its own when it's supposed to, not just that it runs. Replace the failed device, then test each cutout deliberately. Since these are what make the lift safe to operate, the step-by-step procedure is worth following start to finish. Not sure on the procedure? Find your lift in our parts lookup or call and we will walk you through it.
Find the right part for your lift
If you are not sure this part matches your setup, the fastest check is the visual breakdown: open our parts lookup, pick your model, and match your part against the drawing where every item is numbered. Can't read the model plate? our guide to finding your model number shows exactly where it lives on each lift type, and we are a phone call away if you would rather have us confirm it.
Signs of an electrical fault
If the lift runs sometimes and not others, look for a loose or corroded connection. Intermittent operation is the classic signature of a bad connection — a loose lug, a corroded terminal, a pitted switch contact that makes only when it feels like it. With the power safely off, check every terminal for tightness and every contact for pitting and discoloration. Intermittent almost always means connection, not component.
Parts commonly replaced at the same time
Plan the electrical repair as a circuit, not a single part. The components around a failure often share its age, and doing them together while power is off is safer and cheaper than repeat visits. Give us your lift's configuration and we will assemble the matched set.
Safety notes
Before the cover comes off, the power comes off — and gets verified off. Lift controls tie the motor, the interlocks, and the shutoff together, so a careless connection can make a lift move when it should not. Match the diagram, respect the safety circuit, and get help on anything outside your comfort zone.
Before you order
Ordering tip: electrical components are specific to the lift's voltage and phase, so read the plate before you buy. A 208-230V single-phase lift and a three-phase version of the same model do not share the same contactor or motor. Send the markings off the old part and we will confirm the match.
Check your lift's serial before ordering
The most common reason a lift part comes back is not a defect — it is a revision mismatch. Manufacturers change sub-parts between production runs while keeping the same lift model name, so "it fits my lift model" is not always enough. The model plate carries the serial number that pins your lift to a specific run, and that is the number that settles which version of this part belongs on your lift.
Can't find the plate? Measure the old part — overall length, bolt-hole spacing, thread size on anything threaded — and photograph it from a couple of angles. Send that with your lift's brand and rough age and we will match it against the parts breakdowns we service from every week.
Why buy your electrical control component from Auto Lift Services
We install, inspect, and repair automotive lifts every week — the ALS-7453-89 is a part we handle in the shop, not a random SKU we drop-ship. The phone answers if you have a question mid-install — call 800-674-9302 — and every part ships genuine, no aftermarket substitution unless you ask for it.
About this 8523 switch nussbaum
The 8523 switch nussbaum is a direct-fit replacement engineered to restore original manufacturer performance on the lift model it services. Every piece we ship carries the exact dimensional and material specifications the OEM published for that application. Fitment on this component is critical: it interfaces with adjacent hardware in ways that any deviation from spec can drive premature wear on nearby parts or trigger the lift's mechanical safety systems into an unexpected condition. Shops that source this from us instead of a generic aftermarket substitute consistently report zero fitment issues on first-time installation.
Technical specification & installation notes
Technical specification matches the OEM published dimensions to within manufacturing tolerance. When a shop installs the 8523 switch nussbaum correctly, the lift returns to factory-rated performance immediately — no break-in period, no cycle-count adjustment required. The lift's safety systems (mechanical locks, hydraulic pressure relief, and electrical interlocks) treat a correctly-installed replacement exactly as they would treat a factory-original component during initial commissioning. That parity is what lets us honor warranty coverage without asking for the lift's full operating history.
Shipping & ordering
Shipping runs 3-5 business days on standard ground to the lower 48 states. Expedited overnight and two-day options are available; call 800-674-9302 before ordering to quote expedited freight. We stock the 8523 switch nussbaum in Iowa and ship same-day for orders confirmed before 2 PM Central. Orders that come in later than that or on a Friday afternoon pick up on the next business day. A tracking number gets emailed to the address on the order the moment the package leaves our dock.
Warranty coverage
Consumables and wear parts like this are covered under the manufacturer defect warranty for twelve months. Because the 8523 switch nussbaum is a component that eventually needs replacement in normal operation, warranty coverage specifically addresses failure due to manufacturing defect, not failure due to normal end-of-life wear. Our team can help distinguish between the two on a phone call if there is any question after installation — call 800-674-9302 and describe the failure pattern; we will tell you honestly whether it looks like a warranty case.
Cross-reference & fitment
Fitment on the 8523 switch nussbaum is verified against the lift serial number when the order comes in. Even inside one manufacturer's catalog, a lift model built in one production year can carry subtle revisions from the same model built two or three years later. Sending us the lift serial number when you place the order — either in the order notes or in a follow-up email — lets us verify the piece against that specific serial's parts list. That five-minute step catches revision mismatches before shipping and prevents the delay of an incorrect delivery.
