About the Continuous SW182B-12 Reversing Contactors

 Continuous contactors by design are predominantly for drive functions on vehicles; they make and break slower than intermittent solenoids, and are recommended for prolonged contact periods.

 The SW182B is a configuration of two 'Single Pole, Double Throw' type contactors on a common bracket for motor reversing. The SW182B features single pole double breaking main contacts with silver alloy tips, which are weld resistant, hard wearing and have excellent conductivity.

 The SW182B main contact circuit, designed for motor reversing, is such that it has a built in failsafe, so that if both coils are energised simultaneously the contact arrangement is open circuits.

 The SW182B has M8 stud main terminals and 6.3mm spade coil connections. Mounted using the supplied bracket, mounting of the solenoids can be horizontal or vertical, when vertical the M8 contact studs should point upwards.

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).

Magnetic Blowouts

 These contactors are fitted with magnetic blowouts (denoted by 'B' suffix in the SW182B range) across contact gaps. These enable high currents to be ruptured very quickly so that arcing time is reduced to a minimum. Fitting of blowouts can make the contacts polarity sensitive and the positive markings on the top cover of the contactor must be observed.
