About Intermittent (INT.) SW560A Solenoids
Intermittent contactors by design are predominantly used for hydraulic functions on vehicles, they make and break quicker than continuous solenoids and are not recommended for prolonged contact periods.
The SW560A is a compact contactor which can be busbar mounted vertically or horizontally, if mounted vertically the coil should be at the bottom.
Magnetic Latching: Contact position is secured with the use of a permanent magnet within the assembly. The coil requires a pulse to close the contacts, and a reverse polarity pulse to operate the armature and open the contacts, but otherwise remains in the last energised state without the need for power. It should be noted therefore these are not failsafe.
This version of the SW560A unit has an auxiliary microswitch mounted on the top cover, the auxiliary contact connection is triggered by the coil energising.
