Reed Switches - Standard Reed Switches
Our standard KSK reed switch series are our most popular all purpose switches ranging in size from 7-14mm. They may be used as a proximity sensor or internal to a relay. [more]
SPDT Reed Switches
Reed Switches - SPDT Reed Switches
Our SPDT KSK-1C90U and KSK-1C90F reed switch products are a changeover or single-pole double throw switch type. Also use as a Form-B, normally-closed switch (NC) in a relay or sensor. [more]
Latching Reed Switches
Reed Switches - Latching Reed Switches
Our latching or bistable reed switches are a magnetically biased spst switches that will stay On once switched on and off when the polarity is reversed. Used is sensors and relays. [more]

Form A = normally open contact (N. O.)
Form B = normally closed contact (N.C.)
Form C = change over contact (S.P.D.T.)
Form E = Bistable / Latching
AT = Ampere Turns; Parameter that describes magnetic sensitivity.
