About The Intermittent SW202-136 Reversing Contactors

 Intermittent contactors by design are predominantly used for hydraulic functions on vehicles, they switch quicker than continuous solenoids and are not recommended for prolonged contact periods.

 The SW202 is a configuration of two 'Single Pole, Double Throw' type contactors on a common bracket for motor reversing. The SW202 features single-pole, double-breaking main contacts with Silver-alloy tips, which are weld resistant, hardwearing and have excellent conductivity.

 The SW202 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 SW202 has M10 stud main terminals and 6.3mm spade coil connections. The mounting of the solenoid can be horizontal or vertical, when vertical the M10 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).

Magnetic Blowouts

 These contactors are fitted with magnetic blowouts across contact gaps as standard. 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.
