Flush-Mount 16 mm Panel-Mount Push-Button Switches
Because these switches mount flush against a panel, they're easy to clean and hard to damage.
Note: Illuminated switches include a bulb. If wiring the switch and the bulb to the same circuit, the circuit voltage must not exceed bulb voltage.
Switches with quick-disconnect terminals are rated IP40 for parts behind the panel, and IP67 for the front of the panel.

16 mm Emergency Stop Panel-Mount Push-Button Switches
Immediately cut power with a single push. These switches meet EN 418 for compliance with European machine directives for emergency stop applications. They're rated NEMA 4, 13, and IP65 for protection from washdowns and oil/coolant spraying.
Key reset switches are keyed alike, so if you buy multiple switches they will all reset with the same key.

16 mm Panel-Mount Lever Switches
Avoid accidental actuation—these switches won’t turn on or off until you grip and twist the lever. Install in a 16 mm dia. cutout. To help users identify switches without having to read labels, use differently colored switches for different tasks. Rated NEMA 4, 13, and IP65, all are protected from washdowns and oil/coolant spraying.
Three-position switches are off in the center position.
Add a bulb (sold separately) to illuminate switches, so they’re easy to see in dim and dark areas. If wiring the switch and the bulb to the same circuit, the circuit voltage must not exceed bulb voltage.
Use removal tools (sold separately) to replace bulbs and contact blocks.
Mounting wrenches (sold separately) make it easier to install switches in crowded panels.

16 mm Panel-Mount Build-Your-Own Plastic Switches
Choose an actuator and contact block to make your own switch. All switches are rated NEMA 4, 13, and IP65 for protection from washdowns and oil/coolant spraying.
Actuators spring back (momentary), but can be wired to stay switched (maintained).
Add a bulb to illuminate actuators. If wiring the switch and the bulb to the same circuit, the circuit voltage must not exceed bulb voltage.
Use removal tools to replace bulbs, lenses, and contact blocks.
Mounting wrenches make it easier to install switches in crowded panels.

16 mm Panel-Mount Key Switches
Limit access to sensitive equipment—these switches require a key to actuate. Rated NEMA 4, 13, and IP65, they're protected from washdowns and oil/coolant spraying. All are keyed alike, so they open with the same key.
Mounting wrenches (sold separately) make it easier to install switches in crowded panels.
