Solid State AC Switch [PIC-117]

PIC-117 This is a non-mechanical SPST (single pole single throw) relay switch which does not have any moving mechanical part. The switch requires only a minimum of 3.3V 5mA to activate the AC switch. Digital input voltage can range from 3.3V-12V, which is suitable to be controlled by a microcontroller’s low voltage output.

The AC switch is suitable for 110Vac-230Vac operation. Compare to a mechanical relay, which requires a typical trigger input of 5-24V 30-150mA. Mechanical relay for high voltage/current operation will result in arcing, which can weld the contact, forming a permanent joint after long use. This may result in operation failure.

The AC switch is made of semiconductor material and will not have such issues; it does not have any mechanical part. The AC switch will switch during the zero crossing, therefore minimise suddenly surge/spark upon switching on.
