About Intermittent (Int.) SW822-7 Solenoids
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 contactors are compact in size and are fully serviceable, with a full range of spare parts available. The SW822 has M8 stud main terminals and 6.3mm spade coil connections. It can be mounted via the supplied mounting bracket. Mounting 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). |
