Frequently Asked Questions
- Is this suited to timber doors and windows?
Yes. This mini surface mount reed switch is specified as ideal for wooden doors and windows. - Is this a Normally Closed contact?
Yes. The contact type is Normally Closed. - What is a common installation mistake to avoid?
Avoid exceeding the recommended operating gap - if the magnet is positioned too far away the contact may not change state reliably.
Additional Information
- Mini surface contacts are commonly chosen where a larger wide-gap contact would be visually intrusive.
- Plan cable routing before mounting so the 350 mm lead can be dressed neatly into the frame or cavity.
- For doors with larger misalignment or wider clearance gaps, a wide-gap surface mount reed switch may be more suitable.
