Review: Works - Had a broken/shorted micro switch on an electric recliner that's super comfortable. Couldn't bear to toss the chair, so took apart the remote and this was the micro switch in it. Contacts were burned in the old one. You can easily take apart these switches to remove the metal actuator arm, and I did that as I did not need the arm for my application. Snapped back together and desoldered the old one and put this one in and it works great. Only needed one so now I have a bag full if the kids break the remote again.
Review: Works great - Worked great on Sewing machine foot pedals, also added them to another foot pedal to customize switching ononly when pressed.

## Questions & Answers

**Q: What are the size of the holes? I need to be able to use sheet metal screws to attach them.**
A: The holes for the screws are about 0.098" (~2.50mm).  This size hole will not allow you to use a #4 screw. However, there is enough plastic around the hole that I was able to use a 7/64 drill to enlarge it.  Then followed up with an 1/8" drill, which will allow a #4 sheet metal screw to slide through.  So far they seem to be working OK.

**Q: I noticed the switch has quite a bit of force. For my application, I need a lighter touch switch. Is such an option available?**
A: I do not know.  I was not aware that this switch required much force.

**Q: distance between hole centers?**
A: 9.5mm center to center

**Q: what size crimp connectors work on these? They are tiny I know.**
A: I can’t tell you what size they are but I use the push on crimp connectors and they work great. Makes it so much easier to install and change out switches later..
