Frequently Asked Questions (FAQs)
1. What is a magnetic switch used for?
Simple magnetic switches are used to detect the opening of doors and windows. A basic magnetic switch comprises two parts— the magnet and a magnetically sensitive switch (usually a reed switch enclosed within a glass envelope). Switches may be either normally open (close on alarm) or normally closed (open on alarm).
2. What are magnetic switches called?
A reed switch is an electromagnetic switch used to control the flow of electricity in a circuit. They are made from two or more ferrous reeds encased within a small glass tube-like envelope, which become magnetised and move together or separate when a magnetic field is moved towards the switch.
3. Are there magnets in light switches?
Since most keys are made of brass, the keys themselves don't stick to magnets. Only the steel ring is attracted.
4. How does a coded magnetic switch work?
Non-contact coded magnetic switches work by pairing a magnetically-actuated reed contact and specially-coded actuator. In most applications an interlock is a device used to help prevent a machine from harming its operator or damaging itself by stopping the machine when tripped.
