Security system installers and DIY smart home enthusiasts, this Securitron door position switch is your go-to solution for monitoring wood doors discreetly!

This white concealed magnetic switch requires drilling 3/4-inch holes in both the door and frame directly opposite each other for a clean, nearly invisible installation.

The switch is normally closed (SPST), meaning the circuit completes when the door is shut and opens when the door is opened - perfect for security systems, access control, or automation setups.

The activation distance typically ranges from 1/2 to 3/4 inch depending on your door's gap, and the package includes both the magnetic switch and cylindrical permanent magnet.

The white color blends seamlessly with most wood door finishes, maintaining your door's aesthetic while adding important security functionality.

Whether you're setting up a basic alarm system, creating smart home automations, or need reliable door status monitoring for commercial applications, this quality switch delivers reliable performance.
