Larger than 3/8" but smaller than 3/4", the GRI 150RS Series is a one-half inch diameter, flush mount contact. This 1/2" diameter design allows additional "working room" for extra wire, E.O.L. resistors, etc. Manufactured from a special polyvinyl material, the unique collar design will "press-fit" into hollow core aluminum or vinyl clad windows with a "snap-in" fit. The 150RS can be ordered with 12" leads or screw terminals.

The G.R.I. 150RS is paired with a matching 1/2" magnet case to offer the installer a 1/2"+ gap. The 150RS switches can also be paired with any of the wide selection of G.R.I. magnets to help resolve difficult installation applications, including our MF-875. Patent Pending.
