## Description

Product Description

Review: this is a Good product - This is a quality product for a fair price Working at -20C for more than one year zero issues
Review: Nice build quality and great range of adjustments. Installed on pull-down attic stairs(video) - I was looking for a limit switch with several options for adjustments and this switch fits the bill. Sturdy metal body, metal arm and metal roller make this switch seem like it’s built to last. I needed a solution for a switch that turns my attic lights on when accessing the pull-down attic steps. I was fortunate that the switch fit perfectly between the bracket and spring. The switch also includes a water resistant screw down cable nut. This switch is also designed with two circuits that can be wired always on, and always off.

## Questions & Answers

**Q: How many degrees of travel after the switch contacts have been made?**
A: 30 degrees.

**Q: I will be using this as a limit switch on a horizontal bandsaw.  am i correct on my understanding that contacts are rated at 10a @ 300vac?**
A: You could, but I would recommend keeping it under 5A for highly inductive loads if you want the contacts to last. Consider having the limit switch drive a relay.

**Q: normally open or closed?**
A: 1x normally open, 1x normally closed.

**Q: If this cuts the power when the switch is activated, how is power provided to reverse direction?**
A: There are 6 terminals inside the switch. Switch can be wired so that movement of arm in either direction starts or stops current flow. Or wired so that movement of arm in one direction powers in that direction ar movement of arm in opposite direction sends power to that direction.
Switches so farm have performed perfectly.
