The SW80 series of contactors has been designed for direct current loads, particularly motors as used on small electric vehicles such as light industrial trucks, powered invalid cars, etc.
They have double breaking main contacts with silver alloy contact tips, which are weld resistant, hard wearing and have excellent conductivity.
They are economical in price and compare favourably with sealed automotive style solenoid switches which cannot be serviced or inspected for contact wear.
Compact Size: The contactors are compact in size and are fully serviceable with a full range of spare parts available.
Installation: Mounting is by means of 4mm tapped holes in the switch frame together with a range of mounting brackets complete with screws and washers.
