Uninterrupted current - no or infrequent load switching requirements (maintains a lower contact resistance).
The SW63 features single pole double breaking main contacts with silver alloy
tips, which are weld resistant, hard wearing and have excellent conductivity.
The SW63 has M6 stud main terminals and 6.3mm spade coil connections. It
can be mounted via M4 tapped holes or mounting brackets – either supplied
fitted, or as separate items. Mounting can be on the side or base of the contactor.
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).

SW63
The SW63 is a miniature series single pole, free standing, compact
contactor. It is designed to fill the gap between 30 ampere relays and 100
ampere contactors. Devised for both interrupted and uninterrupted loads,
the SW63 is suitable for switching Resistive, Capacitive and Inductive
loads. Typical applications include switching small traction motors,
hydraulic power packs and small electric winch motors.
