Wiring diagram
Caution:
1. AST series products are not suitable for switches arc extinguishing for DC loads.
2. It is recommended that an over-voltage protection circuit be connected between pin 1 and pin 2 of this device, such as a piezoresistor in parallel or an RC absorbed circuit in parallel when it is used in case of over-voltage surge.
3. According to customer needs, pin 1 can connect with a fuse in series, and the rated operating current of fuse is 1/3 to 1/2 of the load current.
