What’s the difference?

Standard UK Light Switches

  • Functionality:
    These are the most common type of switches in UK homes. They toggle between two fixed positions: on and off. Once flipped, the switch stays in that position until manually changed.
  • Use Case:
    Ideal for controlling a single light or appliance with straightforward on/off functionality.

Retractive (Push) Switches

  • Functionality:
    Retractive switches return to their default position (usually off) after being pressed and released. They don’t maintain a fixed on/off state. Instead, they send a momentary electrical pulse.
  • Use Case:
    Frequently used in smart home setups, dimmer systems, or multi-way circuits where a single press might trigger an event (e.g., turning on a smart light or dimming).

Frequently Asked Questions

What is a retractive switch and when do I need one?

A retractive (also called momentary or push) switch returns to its default position after being pressed and released — instead of staying in a fixed on/off position like a standard switch. It sends a momentary electrical pulse, which is exactly what Samotech smart dimmers (SM309/SM309-S, SM323) and 2-way circuits expect for triggering dim, on/off, or scene events.

How is a retractive switch different from a standard UK light switch?

A standard switch toggles between two fixed positions — on or off — and stays in that state until you flip it again. A retractive switch is "normally open" and only closes the circuit while pressed; it returns to its default state on release. Retractive switches are essential for smart dimmer modules and multi-way circuits where a press triggers an event (turn on, dim, scene activation).

Which Samotech modules is this retractive switch compatible with?

The SM-RTRS-V retractive switch is ideally matched to most Samotech Zigbee, Matter, and WiFi modules — including the SM309/SM309-S in-line dimmer modules and SM308-S switch modules, particularly when wiring for 2-way / multi-location control.

What’s the electrical rating?

The switch is a Schneider Lisse GGBL1012RS rated at 10AX, 240V — suitable for fluorescent loads, inductive loads, low-voltage lighting, and the typical loads handled by Samotech smart modules (10–100W).

What back box depth does the switch need?

The technical minimum back box depth is 16mm; we recommend a 25mm back box to comfortably fit the switch alongside a Samotech in-line module behind it. The switch has a raised rounded profile with screwed faceplate.

What cable size do the terminals accept?

The angled in-line terminals accept cable sections from 1mm² up to 2 × 2.5mm² — plenty of capacity for typical UK lighting installations and for daisy-chaining cables.

What material is the switch made from?

The switch is constructed from high-quality urea plastic, which is durable and offers antimicrobial properties. The white plastic finish blends with most modern interiors and includes screw cap covers for a streamlined look.

What’s included in the package?

Each switch ships with: 1 × Schneider Lisse retractive switch (1-gang, 2-way), screw cap covers for a clean finish, and fixings supplied. Backed by a 1-year manufacturer guarantee.
