How to choose this product

reed-switch

Reed switches are small electrical switches that are activated by an applied magnetic field. Configurations include normally open or normally closed.

Applications

Reed switches are used in the automobiles as position sensors, parking sensors and movement sensors. A common application of a reed switch is to detect the opening of a door. In marine applications, reed switches are used to detect liquid levels or anchor position.

Technologies

Reed switches are created by hermetically sealing two ferromagnetic contacts in a glass tube. The contacts have a gap between them which can be altered when a magnet is present. A reed switch can come as either normally open (NO) or normally closed (NC). A reed switch can be used to make a reed relay by surrounding it with a coil.

How to choose

When selecting a reed switch, be sure to provide information such as the rated power (W), the switching voltage (V) and the switching current (A) of your application.

Advantages

- Compact
- Inexpensive
- Availability

Disadvantages

- Sensitive to high voltage
- Sensitive to high current
- Fragile
