HySecurity MX3011, SWITCH, SPDT, 16A, 125V
HySecurity MX3011 is an SPDT electrical switch rated 16A at 125V for select HySecurity operator applications. Current listing data identifies the part as "SWITCH, SPDT, 16A, 125V."
This switch should be matched by part number, switch function, actuator style, terminal layout, mounting style, and the HySecurity parts diagram. Because SPDT switches can be used in different operator locations, MX3011 should not be assumed to be a limit switch, reset switch, hold-open switch, disconnect switch, kill switch, or interlock switch unless the documentation for the specific operator confirms that use.
What This SPDT Switch Does
An SPDT switch provides one common terminal and two switched contact paths, commonly described as normally open and normally closed contacts depending on how the switch is used in the circuit. In a HySecurity operator, the exact function depends on where MX3011 is installed and how the operator wiring diagram uses the switch.
A failed, loose, burned, corroded, miswired, or incorrect switch can cause intermittent control behavior, a failed input, incorrect command response, a switch-related fault, or a circuit that does not change state properly. Similar symptoms can also be caused by damaged wiring, loose terminals, failed controller inputs, broken connectors, incorrect switch adjustment, bad relays, failed contactors, or prior non-factory wiring changes.
Compatible With
Use HySecurity MX3011 only where the operator parts diagram, original switch, or HySecurity documentation confirms this part number.
- Select HySecurity operator applications where MX3011 is listed as the required SPDT switch.
- Repairs where the original switch is marked, listed, or cross-referenced as HySecurity MX3011.
- Applications requiring a 16A, 125V SPDT switch where the mounting, terminals, actuator style, and switch function match the original installation.
- Operator control or switch-circuit repairs where the parts diagram specifically identifies MX3011 for that switch location.
Important Compatibility Warning
Do not order MX3011 based only on the rating "16A 125V" or the term "SPDT." Many switches share similar ratings but have different actuator styles, terminal positions, mounting holes, case sizes, switch actions, and circuit functions.
MX3011 should not be substituted for a safety switch, kill switch, limit switch, reset switch, disconnect switch, or interlock switch unless the operator parts diagram confirms that exact part number. The wrong switch can create incorrect operator behavior or prevent the operator from responding properly.

Related Parts and Accessories
The correct related parts depend on the installed operator model and the circuit where MX3011 is used. Inspect the full switch circuit before ordering only the switch.
- Switch mounting hardware - verify whether it is included or reused from the original installation.
- Wire terminals or connectors - inspect for corrosion, heat damage, loose crimps, or broken conductors.
- Related controller input wiring - inspect if the replacement switch does not restore proper operation.
- Limit, reset, hold-open, disconnect, or kill-switch parts - verify separately if the failed switch is part of one of those circuits.
- Relays, contactors, fuses, and circuit protection - inspect if the switch shows heat damage or repeated failure.
Technician Note
Before replacing MX3011, identify what the switch does in the operator. Check the original part number, switch markings, terminal labels, actuator style, mounting position, and wiring diagram. Do not assume another SPDT switch with the same amp rating will work correctly.
When moving wires from the old switch to the new switch, confirm the common, normally open, and normally closed terminals. Reconnecting wires by physical position alone can change the circuit behavior if the new switch terminal layout is different.
Before Ordering, Confirm
- The required part number is MX3011.
- The operator parts diagram lists MX3011 for the specific switch location.
- The required switch type is SPDT.
- The required electrical rating is 16A, 125V.
- The actuator style, terminal layout, mounting style, and switch action match the original part.
- The repair requires a switch, not a relay, contactor, controller, circuit breaker, limit cam, reset kit, or disconnect assembly.
- The wiring, terminals, connectors, and controller input have been inspected for related problems.
- The package includes the expected switch and any required mounting hardware, or related hardware is ordered separately if needed.
Installation and Service Notes
- Disconnect and secure operator power before servicing any switch or wiring.
- Label the original wires before removing the old switch.
- Confirm common, normally open, and normally closed terminals before reconnecting wires.
- Do not bypass the switch or controller input to force the operator to run.
- Inspect terminals for corrosion, heat damage, loose crimps, or broken conductors.
- After installation, test the exact switch function in the operator, not just continuity at the switch.
- Verify that all stop circuits, limit controls, kill switches, access control safety inputs, and required safety devices remain connected and working properly.
Professional Advisory
Electrical switch replacement should be handled by a qualified gate technician when the repair involves live voltage, control-panel wiring, unknown wire modifications, burned terminals, failed controller inputs, switch safety functions, or unsafe operator behavior. Do not bypass limit controls, stop circuits, kill switches, interlocks, controller protections, access control safety inputs, photo eyes, safety edges, or any required safety devices to keep the operator running.
Product Questions & Answers
What is HySecurity MX3011?
HySecurity MX3011 is an SPDT electrical switch rated 16A at 125V for select HySecurity operator applications.
What does SPDT mean on MX3011?
SPDT means single pole double throw. The switch typically has a common terminal and two switched contact paths, often used as normally open and normally closed contacts depending on the circuit.
What operators use MX3011?
MX3011 should be used only where the HySecurity operator parts diagram confirms this part number for the specific switch location.
Is MX3011 a limit switch?
Not automatically. MX3011 is listed as an SPDT 16A 125V switch. Verify the operator parts diagram before using it as a limit switch replacement.
Can I replace MX3011 with any 16A 125V SPDT switch?
No. The switch rating alone is not enough. The actuator style, terminal layout, mounting style, switch action, and operator parts diagram must match.
What should be checked before replacing MX3011?
Check the original switch markings, terminal layout, wiring, actuator style, mounting position, connectors, controller input, and operator parts diagram before replacing the switch.
Should a technician replace this switch?
A qualified gate technician is recommended if the repair involves control wiring, live voltage, burned terminals, unknown wire changes, safety-related switch functions, or operator behavior that is not clearly diagnosed.
