About Continuous (CO.) Normally Closed SW185 Solenoids
Normally Closed Continuous contactors by design are for an ‘Always On’ line function and break only when the coil is energised, they make and break slower than intermittent solenoids and are recommended for prolonged contact periods.
The SW185 features single pole, single throw, double breaking main contacts with silver alloy tips, which are weld resistant, hardwearing and have excellent conductivity. The SW185 has M8 stud main terminals and 6.3mm spade coil connections. It can be mounted via M5 tapped holes or mounting brackets supplied 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.
