    GRI's recessed switches are most versatile for a variety of applications, but the switch and magnet installed, should never form a "T" configuration
    When the application calls for a wide gap switch, using a bare magnet, keep in mind that GRI's bare magnets are installed with the painted end towards the switch as they are polarity sensitive. When protecting steel doors, use the GRI PA-75 collars with our wide gap switch

    • The Push Button or Plunger actuated PB series was developed in response to installer request for a direct replacement of an existing and problematic mechanical type contact. The PBF-Flanged Push Button can be installed without re-drilling or redesigning the original installation. The sealed contacts of the reed switch insure a long service life.

    Plunger actuated reed switches have also become so popular on new installations that many variations are now being produced. The PB-100 is a press fit design and eliminates the screw mounted flange. A terminal connection is offered on most models and this option can be added by including a "T" at the end of the part number, PB-100T. Mounting hardware is also included where applicable.
