Use reed relays, circuit requirements should be based on the following points: (1) Select the reed relay contacts in the form reed relay contacts are often open (only one set of normally open contacts), normally closed (only one set of normally closed contact) and IS61LV5128AL-10K datasheet and conversion-type (normally open and IS61LV5128AL-10K price and normally closed contacts of a group). The reed and IS61LV5128AL-10K suppliers and the reed 2 and 3 with both conductive magnetic material composition, reed 1 is made of non-magnetic materials, under normal, 1 with the reed 3 reed is closed, when the coil power , reed 2 and 3 closed reed, reed 1 and 3 broken reed. Selection shall be based on the specific requirements of the application circuit to select the appropriate contact form. (2) Select the reed contact form and a voltage application circuit current capacity contr...
