WebAug 21, 2024 · Reed switches come in two main varieties called normally open (normally switched off) and normally closed (normally switched on). The key to understanding how they work is to realize that they don’t just work as an electrical bridge but as a magnetic one as well: magnetism flows through them as well as electricity. WebEntirely disabling the switch seems improper, not only because the light would stay on but because this fridge seems to change its fan behavior depending on the door open/close state. I briefly experimented with taping the sensor to a location much lower on the face of the unit, far enough from the freezer door to avoid it tripping when only ...

WebAdafruit Industries, Unique & fun DIY electronics and kits Magnetic contact switch (door sensor) : ID 375 - This sensor is essentially a reed switch, encased in an ABS plastic shell. Normally the reed is 'open' (no connection between the two wires). The other half is a magnet. When the magnet is less than 13mm (0.5") away, the reed switch closes. WebFeb 3, 2016 · Description. A magnetic contact switch is basically a reed switch encased in a plastic shell so that you can easily apply them in a door, a window or a drawer to detect if the door is open or closed. The switch that we are going to use has two parts: the switch itself, that usually comes opened, and the magnet.
WebA float switch detects the liquid level in a tank or container. The switch floats on top of or within the liquid and acts as a mechanical switch as the liquid level goes up or down. Float switches control devices like pumps (by pumping the water in or out), valves (by opening/closing the inlet/outlets), or alarms to notify users.
