The main purpose of a circuit board is to send electronic signals to other components of an electronic device. This allows signals to flow freely so each part of the device can communicate with all the others.
PVC components used in electrical installations to connect and secure PVC conduits, which are used to protect and route electrical wiring.
PVC (Polyvinyl chloride) is widely used in electrical cable construction for insulation, bedding and sheathing. It was the 1950s when PVC started to replace rubber insulated and sheathed cables in general household wiring due to its ease of processing.
A coupling is used to join two PVC conduits together in a straight line. It has a female socket on each end that fits over the ends of the conduits, which are secured with adhesive or solvent cement.
Caps are used to seal off the end of a conduit to prevent debris or moisture from entering. They are typically used when a conduit run is left open or unfinished.
