About The Intermittent SW88B-27 Reversing Contactors

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

 The SW88B is a configuration of two SW84B type contactors on a common bracket for motor reversing. The SW88B features single pole double-breaking main contacts with Silver-alloy tips, which are weld resistant, hardwearing and have excellent conductivity.

 The SW88B 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 SW88B 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.

Magnetic Blowouts

 These contactors are fitted with magnetic blowouts (denoted by the 'B' suffix in the SW88B 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.
