The George Risk Industries 506-W 10 PACK is a set of 10 surface-mount, single-pole, single-throw, normally closed (SPST-NC) magnetic reed switches. These switches are ideal for applications requiring reliable detection of door or window openings and closings.
Each switch in this convenient 10-pack is designed for easy surface mounting, minimizing installation complexity. The normally closed configuration ensures that a circuit is completed when the magnet is in proximity and is broken when the magnet is moved away.
