It is engineered to function as a localized, maintenance-free control interface that transmits standard Zigbee commands directly to smart hubs, coordinators, and compatible routing nodes.
The hardware maintains a static 0V DC baseline. It requires no battery replacements and no external hardwired mains electrical lines to operate.
The Kinetic Mechanism: Physical depression of a rocker switches an internal spring-loaded, over-center mechanics layout. Once the user applies enough force to pass the structural mechanical threshold, the mechanism snaps instantly.
The Induction Yield: This rapid snap shifts a powerful micro-magnet across a high-density, stationary copper coil loop. The resulting instantaneous change in magnetic flux generates a brief voltage pulse yielding 120 mu J to 210 mu J (microjoules) of raw electrical energy.
Power Management Sub-circuit: The electrical spike is immediately routed into an onboard energy management sub-circuit. It is rectified, smoothed into a stable DC voltage via a low-leakage capacitor bank, and regulated to power the onboard 2.4 GHz Zigbee radio chip long enough to assemble and broadcast its data packets.
Because a kinetic switch must wake up, transmit, and power down before its stored microjoules of energy dissipate, it does not maintain a constant, active polling connection with a coordinator. Instead, it utilizes an efficient, high-speed broadcast protocol.
| Technical Parameter | Specification Value |
| Operating Frequency | 2.4GHz ISM Band (2405MHz to 2480MHz) |
| Wireless Protocol Standard | Zigbee 3.0 / Zigbee Home Automation Stack Compatible |
| Channels Utilized | Operates on Zigbee primary channels (typically 11, 15, 20, or 25 depending on hub assignment) |
| Modulation Scheme | O-QPSK (Offset Quadrature Phase Shift Keying) with DSSS |
| Transmission Window | Data payload assembly and transmission finishes in less than $30\text{ milliseconds}$ |
| Signal Redundancy | Fires up to 3-5 redundant packet bursts per mechanical actuation across the network to guarantee intercept by the closest router node |
The module broadcasts standard Zigbee frames. Smart hubs listening on the mesh network intercept these packets and read the secure data payload embedded inside:
Static Hardware Signature: Every switch contains a unique, factory-assigned 64-bit IEEE MAC address (EUI-64). This identifier acts as the hardcoded identity token used during the initial app pairing phase.
Rolling Sequence Counter: To prevent "replay attacks" (where a malicious party captures a packet out of the air and rebroadcasts it later to manipulate your devices), the switch increments a built-in 32-bit rolling sequence counter with every single click. If a coordinator receives a packet with a sequence number lower or equal to the last one processed, it automatically discards it.
Payload Encryption: The data frame (including button action states) is cryptographically signed using an AES-128 (Advanced Encryption Standard) security key, ensuring data security across your home automation mesh network.
The underlying transmitter module contains four physical contact nipples mapped as Channel A (Left Rocker) and Channel B (Right Rocker).
The specific choice of your Retrotouch glass paddle setup determines the software assignments inside your smart home app:
| Physical Rocker Assembly | Physical Action | Internal Contact Triggered | Ecosystem Translation (e.g., Hue / Home Assistant) |
| 1-Gang (Single Large Rocker) | Press Top Edge | Channel A: Nipple 0 | Target Group/Room: ON or Dim Up |
| Press Bottom Edge | Channel A: Nipple 1 | Target Group/Room: OFF or Dim Down | |
| 2-Gang (Split Dual Rockers) | Press Left Top | Channel A: Nipple 0 | Endpoint 1: ON / Toggle / Scene Activation |
| Press Left Bottom | Channel A: Nipple 1 | Endpoint 1: OFF / Dim Down | |
| Press Right Top | Channel B: Nipple 0 | Endpoint 2: ON / Toggle / Scene Activation | |
| Press Right Bottom | Channel B: Nipple 1 | Endpoint 2: OFF / Dim Down |
The 2.4GHz spectrum provides highly responsive, near-instantaneous communication, but is more vulnerable to material density attenuation than lower sub-GHz frequencies. Structural installation design must align with the following behavior indices:
| Environmental Layer | Structural Attenuation Index | Practical Transmission Range |
| Open-Air Path / Clear Line of Sight | 0% Reduction | Up to 100 meters |
| Drywall / Standard Stud Walls | 10% to 30% Reduction | Up to 15 to 20 meters indoor mesh distance |
| Brick / Reinforced Concrete / Glass Panels | 60% to 90% Reduction | Significantly diminished range. Relies heavily on a nearby mains-powered Zigbee node to repeat the signal. |
| Solid Metal Enclosures / Foil-Lined Drywall | 95% to 100% Reduction | Destroys RF path (Faraday Cage). The switch module must be surface-mounted or used in conjunction with plastic back-boxes. |
