This post is for informational purposes only. Please review the specifications carefully to verify that any replacement or alternate parts are suitable for your application.
This is based on a customer inquiry we had recently, looking for some limit switchs AKA micro switches with markings for a company called “Toneluc.” Finding documentation for these was not possible, but based on the markings and physical size we can find some decent options to replace the old switch. Markings as follows:
MQS-1D
5A 30VDC
- Additionally there was a diagram showing a DPST circuit at the bottom.
- The pins were about 8.5~9mm apart.
Based on the above specifications we can reasonably claim Z8552-ND, made by Omron, to be a good option per the electrical specifications and the PCB footprint.
