Questions about this product
- What's the difference between the 'Normally Open' and 'Normally Closed' plastic switches?
- A 'Normally Open' (NO) switch, like the GPS-14A model, completes a circuit only when a magnet is brought near it. A 'Normally Closed' (NC) switch, like the GPS-14B, has a live circuit that is broken when a magnet comes close.
- You list a few different model numbers, what are the size differences?
- The MKA14103 and GPS-14 models are a standard 2mm by 14mm size. We also have the smaller MKA10110 model, which measures 1.8mm by 10mm for more compact jobs.
- What's the maximum voltage or current these can switch?
- Reed switches are designed for low-power signalling, not for switching mains voltage or high currents directly. They are best used to send a signal to a microcontroller or a relay, which then handles the higher-power load.
