SW84B-2 Albright Single-pole Double-throw Solenoid 12V Continuous

 SW84B-2 single-pole, double-throw solenoid contactor with magnetic blowouts, 12V continuous.

• The SW84B-2 has been designed for 12V direct current (DC) loads, including motors as used on electric vehicles such as industrial trucks. Developed for both interrupted and uninterrupted loads, the SW84 is suitable for switching Resistive, Capacitive and Inductive loads.
• They are economical in price and compare favourably with sealed automotive style solenoid switches which cannot be serviced or inspected for contact wear.

Magnetic Blowouts

 These contactors are fitted with magnetic blowouts (denoted by 'B' suffix in the SW84B 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.

About Continuous (CO.) SW84B-2 Solenoids

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

 The SW84B has M8 stud main terminals and 6.3mm spade coil connections. It can be mounted via M4 tapped holes or mounting brackets purchased as separate items. Mounting can be horizontal or vertical, when vertical the M8 contact studs should point upwards. Please note Normally Closed contacts are not suited to make and break load.
