HySecurity MX4050, Bracket, Breakaway Arm w/Kill Switch Kit
HySecurity MX4050 is a HyProtect breakaway arm bracket kit with kill switch and harness for select HySecurity barrier arm applications. Current listings describe MX4050 as a breakaway bracket with stop switch or kill switch and harness, designed to prevent barrier arm operation after an arm strike.
This kit is commonly associated with HySecurity StrongArmPark DC and WedgeSmart DC operators where the parts diagram confirms fitment. Because breakaway arm hardware can vary by operator model, arm type, harness style, lighting configuration, controller generation, and installation date, MX4050 should be selected only after confirming the original bracket, arm hardware, harness routing, and HySecurity parts diagram.
What This Breakaway Arm Bracket Kit Does
The breakaway arm bracket is designed to release or protect the arm mounting area when the barrier arm is struck. The included kill switch or stop switch circuit is used to prevent continued barrier arm operation after an arm strike, helping reduce additional damage to the arm, bracket, operator, and connected hardware.
A damaged, loose, misaligned, or incorrect breakaway bracket can cause the barrier arm to sit incorrectly, fail to reset properly, trigger a stop/kill switch fault, damage wiring, or prevent the operator from running after an impact. Similar symptoms can also be caused by a damaged kill switch, broken harness, bent arm, damaged pivot hardware, missing magnet, incorrect controller wiring, broken cover, or prior non-factory repairs.
Compatible With
Use HySecurity MX4050 only where the operator parts diagram, original bracket, or HySecurity documentation confirms this part number.
- Select HySecurity StrongArmPark DC applications where MX4050 is listed as the breakaway arm bracket with kill switch kit.
- Select HySecurity WedgeSmart DC applications where MX4050 is listed as the HyProtect breakaway bracket with stop/kill switch and harness.
- StrongArmPark DC arm hardware repairs where the original breakaway bracket kit is marked, listed, or cross-referenced as HySecurity MX4050.
- Applications where the breakaway bracket, kill switch, harness connection, arm hardware, and controller wiring match the HySecurity parts diagram.
- Retrofit or service applications where the technical bulletin or installation instructions confirm MX4050 and the required harness routing.
Important Compatibility Warning
Do not order MX4050 based only on the words "breakaway bracket" or "kill switch." HySecurity uses multiple breakaway bracket parts, covers, harnesses, magnets, arm assemblies, and switch kits depending on the operator family and arm setup.
MX4050 is commonly listed as a breakaway arm bracket kit with kill switch and harness. It should not be treated as the same part as the LED light/kill switch harness, the kill switch by itself, a breakaway cover, a complete barrier arm, or an articulating arm assembly. If the operator has arm lighting, verify the LED light/kill switch harness and connector requirements before ordering.

Technician Note
Before replacing MX4050, inspect the barrier arm, breakaway bracket, cover, hinge/pivot points, kill switch, harness, connectors, target magnet, sensor circuit, arm light wiring, controller connection, and mounting hardware. A no-run condition after an arm strike may be caused by the kill switch circuit doing its job, but it can also be caused by a damaged harness, misaligned switch, broken bracket, bent arm, missing magnet, or controller input fault.
Do not bypass the kill switch or stop switch circuit to keep the operator running after an impact. If the arm was struck, inspect the complete arm system and reset or replace damaged parts according to the service procedure before returning the operator to normal use.
Before Ordering, Confirm
- The required part number is MX4050.
- The operator is a StrongArmPark DC, WedgeSmart DC, or other approved application where the parts diagram lists MX4050.
- The repair requires the breakaway arm bracket with kill/stop switch and harness, not only a switch, harness, cover, magnet, light strip, or arm assembly.
- The installed arm style, bracket style, lighted-arm setup, and controller connection match the HySecurity documentation.
- The existing harness, kill switch, target magnet, sensor circuit, and arm light wiring have been inspected.
- The operator has not been modified with non-standard arm hardware or non-factory breakaway wiring.
- The package includes the expected bracket, switch, harnesses, and hardware, or any missing related parts are ordered separately.
- Retrofit installations are checked for any required chassis hole, harness routing, and controller connection requirements.
Installation and Service Notes
- Disconnect and secure operator power before servicing breakaway bracket wiring or arm hardware.
- Support the barrier arm properly before removing bracket or pivot hardware.
- Do not bypass the kill switch, stop switch, breakaway switch, controller protection, or safety inputs.
- Route harnesses so they are not pinched by the arm, bracket, cover, pivot, or breakaway movement.
- Confirm switch alignment and magnet/sensor relationship where applicable.
- After service, verify breakaway bracket reset, kill/stop switch operation, arm lights where applicable, controller response, arm travel, and all required safety devices.
- If the arm was struck, inspect the arm, mounting hardware, enclosure, bracket cover, and harness before returning the operator to service.
Professional Advisory
Breakaway arm bracket and kill switch repairs should be handled by a qualified gate technician when the repair involves impact damage, heavy or long barrier arms, lighted arm harnesses, controller inputs, switch alignment, chassis drilling, non-factory wiring, or unknown prior modifications. Do not bypass kill switches, stop circuits, breakaway switches, limit controls, controller protections, access control safety inputs, photo eyes, safety edges, or any required safety devices to keep the operator running.
