SPX Stone 4610-AA Start Switch Button — 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-7004-29 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.

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 Want to be sure before you buy? Pull the model and serial off your lift's plate and open our parts lookup to open the exploded parts breakdown for your model — find your part on the drawing and you know it fits. New to finding your model number? our guide to finding your model number covers it, or send a photo of the plate and we will read it for you. 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-7004-29 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 4610 spx stone Every order for the 4610 spx stone starts with a fitment confirmation. Two lifts of the same model can carry subtle revisions between production years, and a component that fits a rev-A lift may not fit a rev-B lift built two years later. Before your card is charged we verify the piece against the parts breakdown for your specific lift serial number. That five-minute step is the difference between the part arriving and being installed the same afternoon versus the wrong piece showing up and the shop losing a day of billable work. Technical specification & installation notes Technical specification matches the OEM published dimensions to within manufacturing tolerance. When a shop installs the 4610 spx stone 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 Freight covers the continental United States on all standard orders. We ship UPS or FedEx ground for parts under 30 lb; heavier assemblies quote at published carrier rates. International orders on the 4610 spx stone require a freight quote — email dimensions, weight, and destination country to [email protected] and we return a rate within one business day. Alaska, Hawaii, and US territories quote at published rates and typically take five to ten business days depending on carrier and destination. Warranty coverage Consumables and wear parts like this are covered under the manufacturer defect warranty for twelve months. Because the 4610 spx stone 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 Cross-reference on the 4610 spx stone is straightforward: match the OEM part number from the lift's parts breakdown against the number on your original invoice. If the numbers match, the component fits. If your lift's parts breakdown lists a superseded or alternate number, we accept the superseded value on the phone as confirmation of fit. When a manufacturer has issued a running change during production, we track the change in our catalog so ordering by the older number automatically pulls the current-spec replacement.
