Recessed 1/2" Switch Set - 150 Series - 10 Pack - 10 Pack

Larger than 3/8” but smaller than 3/4”, we introduce our newest innovative switch design, the one-half inch diameter, flush mount, 150-12. This new design is in response to requests from our customers for a switch that would give them additional “working room” for extra wire, E.O.L. resistors, etc., yet would more readily install in the increasingly popular hollow core windows. The 150-12 is a 1/2” diameter contact, manufactured from a special polyvinyl material with a unique collar design that will “press-fit” into wooden or vinyl clad windows with a “snap-in” fit for hollow core vinyl or aluminum windows.

The 150-12 is paired with a matching 1/2” magnet case to offer the installer up to a 1” gap. The 150 switch can also be paired with any of the wide selection of our magnets to help resolve difficult installation applications, such as our MF-875.
