Operating Characteristics

The following examples show typical operating characteristics of a reed switch. Generally, when a reed switch is actuated by a permanent magnet, the ON-OFF region differs depending on the type and Operate AT of the switch, and size and power of the permanent magnet. The ON region corresponds to the Operate AT and the ON region and the Hold region together corresponds to the Release AT of the Reed Switch. These characteristics will vary if there is any other Ferro-magnetic material nearby. Each characteristic curve will be enlarged as a whole if a stronger magnet is used for actuation, or if the Operate AT of the reed switch is low.
