Honeywell Plunger Limit Switch, SPDT, 28V DC - CH Series - 1CH28-12
Automate industrial machine processes with this plunger limit switch from Honeywell. The switch works by opening or closing a circuit when an object presses down on its plunger. Its SPDT (single pole double throw) configuration means it can control two circuits at once, helping to increase efficiency in your work environment. Thanks to its current rating of 4A, this limit switch is suitable for use in low-current applications. This switch has compact dimensions of 65.913 (height) x 25.4mm (diameter), so it will add minimal bulk to your equipment.
Features & Benefits

What's overtravel?
Overtravel is the extra distance that a switch's plunger can be pushed without harming the switch. It allows the switch to break the circuit and shut down a machine when it detects excessive force to prevent damage to equipment.
