Honeywell SP-CO Plunger Microswitch, Screw Terminal, 15A - BZ Series - BZ-2RQ18-A2

Use this snap-action plunger microswitch from Honeywell to convert mechanical energy into an electrical signal. It features silver contacts that provide good conductivity and ensure a secure connection. It's also housed in a sturdy phenolic case that's resistant to wear and burns, making it a good choice for use in extreme environments. A low operating force of 2.5 to 3.61N means it's sensitive enough to ensure quick response times in a variety of industrial and commercial applications.
