Big Gap Surface Mount Reed Switch, White
Built as a surface mount reed switch for door and window security applications, the Big Gap CSD-2001 accommodates larger-than-standard gaps between the magnet and switch body, giving installers more flexibility where tight alignment isn't possible. Its white finish suits most residential and light commercial environments. Compatible with standard alarm control panels.
Why This Model
- Big gap tolerance: The extended operating distance between magnet and switch means reliable detection even on warped frames or uneven surfaces where standard reed switches would false-trigger or miss activations.
- Surface mount design: Mounts directly to the face of doors, windows, and frames without routing or rebating, keeping installation fast and non-destructive.
- White finish: Blends with painted timber, uPVC, and aluminium frames commonly found in Australian homes and commercial fit-outs, reducing visible hardware impact.
