When coil voltage is removed, a return spring moves the armature back, and the contact returns to the NC position. The SPDT (1C) configuration allows switching between two circuits.","pin_description":"<table><tr><th>Pin<\/th><th>Name<\/th><th>Function<\/th><\/tr><tr><td>1<\/td><td>Coil A<\/td><td>Coil terminal A<\/td><\/tr><tr><td>2<\/td><td>Coil B<\/td><td>Coil terminal B<\/td><\/tr><tr><td>3<\/td><td>COM<\/td><td>Common contact<\/td><\/tr><tr><td>4<\/td><td>NO<\/td><td>Normally open contact<\/td><\/tr><tr><td>5<\/td><td>NC<\/td><td>Normally closed contact<\/td><\/tr><\/table>","application_scenarios":"<ul><li>Signal routing in communication equipment<\/li><li>Audio\/video signal switching<\/li><li>Instrumentation signal multiplexing<\/li><li>Industrial control signal switching<\/li><\/ul>","alternative_models":"<table><tr><th>Model<\/th><th>Manufacturer<\/th><th>Key Spec<\/th><th>Package<\/th><\/tr><tr><td>G6K-2F-Y 5VDC<\/td><td>Omron<\/td><td>5V signal relay 2A<\/td><td>Subminiature<\/td><\/tr><tr><td>TX2SA-4.5V<\/td><td>Panasonic<\/td><td>5V signal relay 2A<\/td><td>Slim<\/td><\/tr><tr><td>IM03 5VDC<\/td><td>TE Connectivity<\/td><td>5V signal relay 2A<\/td><td>Subminiature<\/td><\/tr><\/table>"},"_links":{"self":[{"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/posts\/9803","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/comments?post=9803"}],"version-history":[{"count":0,"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/posts\/9803\/revisions"}],"wp:attachment":[{"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/media?parent=9803"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/categories?post=9803"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/tags?post=9803"},{"taxonomy":"chip_brand","embeddable":true,"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/chip_brand?post=9803"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
