Cautions of Latching Relay:1. Suggestions of relay's input
(1) Polarity- Please check the polarity inside of our technical specification, if a single coil then"+ -" or "- +"is fine,
(3) Contact status may be changed during transportation or installation due to the impact of external force,
therefore please reset to the required status.
(1)When choosing the relay with a hard connection, please avoid the external force on load terminals during or after
