EVO Contact Input Modules – Traditional switches meet modern control.

The contact input module for lighting control allows standard momentary switches to become part of a fully integrated, centralised lighting control system. Designed for projects where traditional switch aesthetics are preferred, EVO contact input modules provide advanced control without introducing keypads, apps, or touchscreens.

By using a contact input module for lighting control, designers and engineers can retain familiar wall switches while enabling scene selection, manual dimming, and custom trigger actions. This makes the system intuitive to use while still delivering the flexibility expected from modern lighting control solutions. The approach is simple, discreet, and ideal for environments where visual consistency and ease of operation matter.

EVO contact input modules convert simple switch inputs into programmable control commands within a lighting system. Each input can be configured to respond to different actions such as press, hold, release, or timed events. This allows a single switch to perform multiple lighting functions depending on how it is used.
When integrated with a centralised lighting controller, a contact input module for lighting control can trigger scenes, adjust light levels, or activate system logic across multiple circuits and areas. This makes it a powerful solution for both small and large projects.
Contact input modules are widely used across hospitality, residential, commercial, and heritage projects. They are particularly well suited to listed buildings, boutique hotels, restaurants, and high-end homes where maintaining a classic switch style is essential.
