2013年7月30日 · You could fix that with a transistor, a resistor and a diode to make a circuit that works around the other way, OR you could switch the relay using a microswitch or similar that …
Reed Switch Hookup Guide - SparkFun Learn
Reed switches are a perfect trick for non-contact activation applications. We used a reed switch to detect when the doors of this TARDIS-themed music box opened. Or you can hook a large, …
Protection Circuits for Reed Switches - Magnetic Reed Switches and Reed ...
The simplest Suppression Circuit is to place a resistor in series with the reed switch and as close to the reed switch to limit the surge current. Shown below are typical examples of protection …
Reed switch melting closed in simple LED circuit -- What resistor …
Let's assume you have a 12V relay with a 200Ω coil... 12V/200Ω = 60mA of current in the coil. That also leaves plenty of margin for the reed switch (max of 200mA). Note that relays come in …
