BC Magnetic Reed Switch

### Magnetic Reed Switch (BC Type) Overview

1. **Functionality**: A magnetic proximity sensor that consists of a pair of ferromagnetic reeds sealed in a glass tube with inert gas. These reeds are normally open contacts that close in the presence of a magnetic field.

2. **Operation**: When a magnet is brought near the switch, the reeds inside the glass tube come into contact, allowing electrical current to flow through the switch.

3. **Applications**:

– **Security Systems**: Used in doors and windows to detect opening and closing.

– **Proximity Sensing**: Detects the position of objects and equipment in industrial applications.

– **Switching Circuits**: Actuates circuits based on the presence or absence of a magnetic field.

### Typical Uses:

– **Alarm Systems**: Triggers alarms when doors or windows are opened unauthorized.

– **Automation**: Detects the position of movable parts in machinery and equipment.

– **DIY Electronics**: Used in hobbyist projects for detecting magnetic fields and triggering actions based on proximity.
