Need a NC Button

[chasjabber]

I want to use a sensor as an “on” switch, replacing the Reed switch with a Normally Closed button. Want a small one that fits on the sensor. Anyone already do this so I don’t have to search around for this button?

Thanks

I haven’t seen a tiny button that I remember, but there have been a few that made modifications to act as a button. Here’s one:

Modifying Wyze Contact Sensor to act as a Button

[IMG_20191217_105358] Video here I tore apart one of my Wyze Contact Sensors the other day. The sensor uses a simple reed switch to detect when a magnet is present, closing the circuit. I desoldered the reed switch and wired up a Cherry MX switch I had lying around. I also 3D printed a quick casing up and made a button that allows me to trigger lights on and off. I also got this working with a toggle switch, but it only allows two states: on and off. You can add more functionality by addin…

Here’s another with a 2d printer file:

Wyze Smart Button

Does seem like it would need much. The few people that have used this seem to say it works. I think what I have made needs a lot of work. But it should just be as simple are a wyze sense with a button on it instead of a magnetic reed switch or even an accessory like I have made. However custom notifications and labeling would be needed. One nice part about making a series of accessory attachments would be that the sensor could be repurposed if it isn’t needed in that configuration any more. …

I am still working on my button btw. I ran into a few roadblocks because the PLA would lose its spring after a while. I am getting other types of filaments and have other designs in the works as well. Hope to have something soon. But If I you wont need to solder anything. You will just be able to pop it into a bracket.
