About the KB-4473-W

The GRI 4473-W is a white, wired recessed magnetic contact switch set for doors and windows, built for installers and homeowners who want a concealed sensor. It pairs a 3/4″ press-fit switch with a 3/8″ rare earth magnet from GRI's Mighty Mag Series, which is under 1/8″ high and meant for the thinner vinyl windows where drilling can cause damage. The closed-loop, normally open design and hermetically sealed construction make it a straightforward choice for wired alarm circuits.

Key features

  • The Mighty Mag Series magnet is less than 1/8″ high, so it installs quickly without risking damage to thin vinyl windows.
  • A rare earth alloy lets GRI shrink the magnet while keeping or improving the gap.
  • Paired with GRI's 3/8″ press-to-fit contacts, the series offers a standard gap of 3/4″+ and 1″+ on wide gaps.
  • The switch is hermetically sealed, and its plated contacts resist sticking or freezing.
  • The recessed 3/4″ switch press-fits into place and uses a closed loop.
  • Connection is by 12″ #22AWG leads or screw terminals.
