SW822 Paired Double Pole Single Throw for Motor Reversing
(Part of the SW80 Series)
The SW822 has been designed for Motor Reversing applications with direct current loads,
particularly motors as used on electric vehicles such as industrial trucks. Developed for both
interrupted and uninterrupted loads, the SW822 is suitable
for switching Resistive, Capacitive and Inductive loads.
•t
Interrupted current - opening and closing on load with
frequent switching (results in increased contact resistance).
•t
Uninterrupted current - no or infrequent load switching
requirements (maintains a lower contact resistance).
The SW822 features single pole double breaking main contacts with
silver alloy tips, which are weld resistant, hard wearing and have
excellent conductivity. The SW822 has M8 stud main terminals and
6.3mm spade coil connections. Mounted using supplied brackets,
mounting can be horizontal or vertical, when vertical the M8 contact
studs should point upwards. If the requirement is for downwards
orientation we can adjust the contactor to compensate for this.

The SW822 has fast drop out times and relatively slow pull-in
times. Motor direction changes can be undertaken without risk of all
contacts being closed at the same time. Note, some coil
suppression such as diodes substantially increase drop out times
and care must be taken to ensure suitable suppression is used (e.g.
diode and resistor in series).
