George Risk Industries 150RS 1/2-Inch Recessed Switch Set

Create a concealed magnetic opening point on protected doors, windows, cabinets, and similar movable openings. George Risk Industries 150RS-12-B is a recessed magnetic switch set that changes state when its matching magnet moves away from the switch. Recessed placement keeps the sensing components largely hidden within the mounting surfaces rather than exposed on the face of the frame. The short 1/2 in recessed format fits applications where mounting depth is limited and a compact drilled installation is required. Install the switch body in the fixed frame and align the magnet with it on the moving surface so the two components meet in the closed position. The attached 12 in leads provide a defined connection length for terminating the contact into compatible low-voltage security wiring. This version combines the short recessed body with a brown housing finish, making it suitable for brown door frames, window frames, or cabinetry where a closer visual match is wanted. The switch-and-magnet set supports a complete sensing point without requiring separate contact and magnet selection. Its recessed construction differentiates it from surface-mounted contact hardware and helps preserve the appearance of finished architectural surfaces.
