About Intermittent (INT.) SW500 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 SW500 is a compact contactor that can be busbar mounted vertically or horizontally. If mounted vertically, the coil should be at the bottom.

 Magnetic Latching: The 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.
