INGCO S-HG-SW-HG20008, Switch PCB(S-HG-SW-HG20008)

product details:

In a heat gun, the switch PCB (Printed Circuit Board) assembly plays a critical role in controlling the flow of electricity and functionalities like power on/off and potentially variable temperature settings. Here’s a detailed breakdown of its components, functions, and replacement considerations:

Components:

The switch PCB assembly typically consists of several key components:

• Switch: This is the physical part you press or turn to activate the heat gun. It can be a simple on/off switch, a rocker switch with variable settings, or a more complex electronic switch depending on the model.
• Printed Circuit Board (PCB): This is a thin board made of insulating material with conductive tracks and pads. It serves as a foundation for mounting the electronic components and allows them to communicate with each other.
• Electronic Components (Variable Speed Models): In heat guns with variable temperature control, the PCB might house additional components like resistors, capacitors, and a triac (electronic switch). These components work together to regulate the power delivered to the heating element, influencing the air temperature output.
• Connectors: These connect the switch PCB to the power cord and the heating element within the heat gun.

Functions:

The switch PCB assembly has two main functions:

• Power Control: When you activate the switch, the circuit is completed, allowing electricity to flow from the power cord to the heating element. This activates the heating element and generates hot air.
• Temperature Control (Optional): In models with variable temperature settings, the switch PCB regulates the power delivered to the heating element. This can be achieved through a dial or buttons on the switch that interact with the electronic components on the PCB to adjust the heat output.
