The Qubic System Motion-Lock Switch is a wired, dual-state control for the MOTION-LOCK subsystem. Pressing the switch immediately stops connected compatible Qubic System devices, while the dual-channel design also monitors the wiring. Two independent contacts, an integrated status LED and support for daisy-chaining multiple devices make it easier to control an advanced motion setup.

| Device | Compatibility | Notes |
|---|---|---|
| Qubic System QS-210 | Yes | The switch is included with the platform as standard |
| Qubic System QS-220 | Yes | The switch is included with the platform as standard |
| Qubic System QS-S25 | Yes | The switch is included with the system as standard |
| Qubic System QS-V20 | Yes | The switch is included with the system as standard |
| Qubic System QS-BT1 | Yes | Optional accessory; the QS-BT1 can operate without a separate switch |
| Qubic System QS-CH2 | Yes | Optional accessory; the device normally connects to a QS-210 or QS-220 system, so an additional switch is usually unnecessary |
| Qubic System QS-DD-20 | Yes | Can operate in the same chain or on an independent MOTION-LOCK circuit |
| Other Qubic System devices | Conditional | A MOTION-LOCK subsystem is required; check the current manufacturer compatibility guide for the specific hardware revision and any required adapter |
1. What does the Qubic System Motion-Lock Switch do?
When pressed, it stops connected devices that support the MOTION-LOCK subsystem. It can control a single device or an entire chain of compatible components.
2. Does the switch operate at hardware level?
Yes. MOTION-LOCK combines hardware and software functions, while the stop request is handled directly by the subsystem. Its response therefore does not depend on in-game button support.
3. Which devices are compatible?
It works with Qubic System products equipped with the MOTION-LOCK subsystem. Confirmed examples include the QS-210, QS-220, QS-S25, QS-V20, QS-BT1, QS-CH2 and QS-DD-20.
4. Is the switch included with Qubic System motion platforms?
Yes, it is included as standard with systems including the QS-210, QS-220, QS-S25 and QS-V20. A separately purchased unit can serve as a replacement or an additional control point for a compatible configuration.
5. Can one switch stop several devices?
Yes. Devices can be daisy-chained through their MOTION-LOCK inputs and outputs. The manufacturer describes the number of units supported in one chain as virtually unlimited.
6. Can independent MOTION-LOCK circuits be created?
Yes. This allows different device groups to be stopped separately, for example the motion platform, QS-DD-20 wheel base and QS-BT1 belt tensioner.
7. Why does the switch use two contacts?
The two independent contacts provide two control channels. If one contact fails, the other can still stop the device, while the MOTION-LOCK subsystem detects and reports the fault.
8. What does the LED indicate?
The LED flashes while a device is in motion. It remains steadily lit after the system has stopped, making the current state easy to identify.
9. Where should the switch be installed and how often should it be tested?
Install it close to the user, within easy reach from the driving position. The manufacturer recommends testing its operation at least once a month and after any wiring changes.
10. Does MOTION-LOCK replace a certified emergency power-disconnect system?
No. The MOTION-LOCK input is not SIL- or PL-rated and does not guarantee functional safety. It is designed to stop compatible devices; installations requiring certified energy isolation must use appropriately engineered external safety equipment.
11. How long is the warranty for Qubic Systems products?
Simline is the largest authorised distributor of Qubic Systems in Poland and Europe. As an authorised Qubic Systems partner, all products from this brand are covered by full warranty protection for up to 2 years within the European Union, in accordance with Qubic Systems warranty terms.
12. How do I submit a warranty claim for a Qubic Systems product?
Simline.eu is an authorised Qubic Systems partner, so we act as an intermediary in the warranty process and handle submissions. Please email support@simline.eu or qubicsystem@simline.eu with photos and videos showing the defect, a description of the issue, and pack the equipment for collection.
