About Continuous (CO.) SW181-16 Solenoids

 Continuous contactors by design are predominantly for drive functions on vehicles, they have weaker coils, switch slightly slower than intermittent solenoids and are recommended for prolonged contact periods.

 The SW181 has M8 stud main terminals and 6.3mm spade coil connections. It can be mounted via M5 tapped holes or mounting brackets purchased as separate items. Mounting can be horizontal or vertical, when vertical the M8 contact studs should point upwards. Please note Normally Closed contacts are not suited to make and break load.

Interrupted current - opening and closing on load with frequent switching (results in increased contact resistance).
Uninterrupted current - no or infrequent load switching requirements (maintains a lower contact resistance).
