Compact Safety Limit Switches
Shorter and thinner than other safety limit switches, these are sized to fit tight spaces. They protect machinery and ensure the safety of personnel. Positive-force contacts open the circuit when actuated, even if a spring fails or the contacts stick. When an object in motion comes into contact with the actuator, it sends a signal to open or close a circuit. They’re often used on conveyor systems and bin filling operations. All are NEMA and IP rated for protection from washdowns.
Styles E and F have an actuator that allows you to adjust its height, making it easier to align switch with the target during installation.
NEMA 13 and IP67 rated switches are protected from oil/coolant spraying and temporary submersion.

Durable Disconnect Switches
Protected by a steel enclosure, these switches withstand tougher conditions than switches in a plastic housing. Also known as safety switches, they have quick-make/quick-break action to eliminate arcing and prolong switch life. A safety interlock keeps the door closed when the switch is on, and prevents the switch from turning on when the door is open. They have a lockout to secure in the off position using a padlock (not included).
Use switches with a fuse holder where overload protection is needed. When used with UL Class RK1, RK5, or T fuses, they require rejection-style fuse clips. Note: Horsepower ratings are based on time-delay fuses installed.

Outdoor Durable Disconnect Switches
A raintight NEMA 3R rated enclosure protects these switches from falling liquids and light splashing. The enclosure is steel, so it withstands tougher conditions than plastic enclosures. All have quick-make/quick-break action to eliminate arcing and prolong switch life. They have a lockout to secure in the off position using a padlock (not included).
Use switches with a fuse holder where overload protection is needed. When used with UL Class RK1, RK5, or T fuses, they require rejection-style fuse clips. Note: Horsepower ratings are based on time-delay fuses installed.
Switches with safety interlock keep the door closed when the switch is on, and prevent the switch from turning on when the door is open.
