About The Continuous SW182-2 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 SW182 is a configuration of two 'Single Pole, Double Throw' type contactors on a common bracket for motor reversing. The SW182 features single pole double-breaking main contacts with Silver-alloy tips, which are weld resistant, hardwearing and have excellent conductivity.
The SW182 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 SW182 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: The opening and closing on load with frequent switching (resulting in increased contact resistance). |
|Uninterrupted Current: No or infrequent load switching requirements (maintains a lower contact resistance). |
