Voltage ratings at (or to): 24V DC
Amperage - Continuous (or to): 100A
SW84-4 single pole, double throw solenoid contactor 24 volt dc continuous.
- The SW84-4 has been designed for 24V 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.

- 2070-124 Auxiliary microswitch kit.
- 2126-48A Mounting bracket.
- Height including terminals and coil base cap: 91mm.
- Coil width: 40mm.
- Cap width: 39mm.
- Coil and cap depth, including fixed contact bars: 58mm.
About Continuous (CO.) SW84-4 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 SW84 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.
|Interrupted current - opening and closing on load with frequent switching (results in increased contact resistance). |
|Uninterrupted current - no or infrequent load switching requirements (maintains a lower contact resistance). |
