Albright SW68-45, 27 volts DC 80 Amps DPST Normally Open (NO) switch contactor, continuous.
- The SW68 type of solenoid contactors has been designed for direct current loads, including motors, as used on electric vehicles such as industrial trucks.
- Developed for both interrupted and uninterrupted loads, the SW68 is suitable for switching Resistive, Capacitive and Inductive loads.
- The SW68 features double pole double-breaking main contacts with Silver-alloy tips, which are weld resistant, hardwearing and have excellent conductivity.
- Due to its small form build, repair kits are not available for this unit.

About Continuous (CO.) SW68-45 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 SW68 features double pole double-breaking main contacts with Silver-alloy tips, which are weld resistant, hardwearing and have excellent conductivity. The SW68 has M6 stud main terminals and 6.3mm spade coil connections. It can be mounted via M4 tapped holes or using various mounting brackets supplied as separate items.
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). |
