The US Automatic 590050-2PK includes two replacement limit switches for Patriot RSL slide gate opener service. The pair is commonly used when replacing both open and close limit switch positions or when keeping one spare on hand during field service.
When a limit switch fails, the gate may stop inconsistently, overtravel, fail to stop at the cam point, or require repeated limit adjustments. Physical damage, corrosion, loose wiring, or worn limit cams can also cause similar symptoms, so the full limit mechanism should be inspected.
This is a slide gate opener part, not the Patriot swing actuator limit assembly. Patriot RSL slide operators and Patriot swing actuators use different limit components, and the wrong part can cause improper travel or damage.

| Part Number | 590050-2PK |
| Application | Patriot RSL slide gate opener limit system |
| Operator Type | Slide gate operator |
| Function | Open / close travel limit signal |
| Included Components | Two limit switches |
| Notes | Do not confuse with 510103 Patriot swing actuator limit switch assembly |
If a Patriot RSL is missing its stop point, check both the switch and the limit cam adjustment. A good switch cannot stop the gate correctly if the cam is loose, worn, or not contacting the actuator lever.
Limit switch service should be done with the gate secured and power removed. After replacement, run a controlled test cycle and verify stop positions, safety devices, and obstruction response.
Yes. The 590050 is for Patriot RSL slide gate opener limit switch applications where the parts diagram calls for it.
No. Patriot swing actuators use the 510103 actuator limit switch assembly. The 590050 slide limit switch is not interchangeable with that part.
On an older operator, both open and close switches may have similar wear or corrosion. The 2-pack is useful when servicing both positions.
It can fix overtravel caused by a failed switch, but loose cams, bad wiring, worn chain components, or a dragging gate can also cause limit problems.
This listing is for the switch or switch pair, not a full mechanical cam assembly unless otherwise shown in the product images or parts list.
