2020 Series 3/8" Press Fit Magnetic Switch Sets



This Switch is CLOSED when the magnet is near.

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.
