Hi Gary, I appreciate the quick response. We have worked with suppliers like your company in the past and submitted these types of switches to UL as part of the end-use application. Our goal now, however, is to source a switch already having the needed agency approvals. Once we have such a source identified, it becomes a rather simple, paperwork project to add that source to the doc report for our product.
We not only want to avoid the initial testing and investigation of the switch, but also the ongoing, periodic follow-up testing required. All of this is quite expensive and better left to the switch manufacturer. Thanks again for your reply. Good day, Richard I.

We make input panels for folks like you, the medical, ITE, and military systems. We don't typically just provide a "switch" since they are really stack-up of parts, pcb contacts, metallic domes or elastomer to provide the feel and long life needed. I'm presuming that if these are low voltage then the issue is 100,000 cycles - we typically run our panels to 1,000,000 cycles as part of our internal qualification process. We used to recognized these things by membrane type, and I think its still valid - but I haven't touched this file in better than two years - again we generally do it as a recognized assembly. E173439 I'm not really a sales guy - but I'm certain that we could meet your needs and I can have one of our folks talk with a little more - I really do the Reliability/Compliance issues EMC, Safety, and Specification test and verification stuff.

This switch would mount under a silicone overlay. There seems to be many such switches available but, so far, we haven't identified any having the required agency approvals. Even though the switch will be used in a low voltage, low current part of the circuit, the end-use product standard (commercial food machinery) requires an 'approved' switch in this safety circuit. Thanks in advance for any and all suggested sources for this switch. Good day, Richard I.
