FK282

An encased magnetic reed switch is held open by a magnet so that when the two are separated, as in the opening of a door, the switch closes and initiates a musical door chime sound. The FK282 not only demonstrates the working of a reed switch it is also ideal for use in shops and domestic situations, to indicate that a visitor or customer has passed through the doorway.
