    Rugged enough for mining operations, these limit switches require a high actuation force, like heavy rocks moving on a conveyor. They open and close a circuit as quickly as a snap-acting switch but have a larger actuator for larger objects. The roller on the end of the lever arm reduces friction to prevent wear and tear on the switch. Rated NEMA 4 and 13 as well as IP67, these switches are protected from dirt, oil spraying, and temporary submersion.
    To determine if you need a right or left actuation direction, stand facing where you'll put the switch. If objects will be passing to the right, you'll need a right actuation direction. If they'll be passing to the left, you'll need a left actuation direction.
