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.

Foot Switches
Keep your hands free for other tasks by triggering switches with your foot.
Front-pivot switches reduce fatigue by letting you rest your foot on them. They won't actuate until you lean into them with your bodyweight. Optional guards prevent accidental switch actuation.

Subminiature Wet-Location Snap-Acting Switches
Small enough to fit in the tiniest spaces, these switches are rated IP67 for protection from temporary submersion. They open and close circuits quickly to minimize arcing and prevent contacts from sticking. They’re often used as door-open indicators on appliances and enclosures or as internal components in limit, pressure, and temperature switches.
Switches with a plunger actuator require a push to actuate.
Switches with a lever actuator have an arm that increases the size of the actuation surface.
Switches with a roller lever actuator allow parts to glide across the actuation surface with less friction than standard levers.

Miniature Snap-Acting Switches
Smaller than standard size snap-acting switches, these fit in tight spaces. They open and close circuits quickly to minimize arcing and prevent contacts from sticking. They’re often used as door-open indicators on appliances and enclosures or as an internal component in limit, pressure, and temperature switches.

Tilt Switches
Often used as position indicators, pump level controls, and machine limit switches, these switches actuate when tilted to a certain angle. They mount horizontally and activate when tilted downward, and deactivate when tilted up. Differential angle is the total angle from the point of activation to the point of deactivation. All combine electromechanical and solid state technologies for reliability and long life.

DIN-Rail Mount Solid State Interface Relays
With no moving parts, these solid state relays last longer, switch faster, and are quieter than mechanical relays. They interface between your controller and components to isolate input and output circuits, which protects components from voltage spikes, amplifies the relay’s signal, and reduces interference for reliable transmission. The included relay socket mounts on 35 mm DIN rail (also known as DIN 3 rail) for fast installation. Relays disconnect from the socket for easy replacement. Rated IP20, they prevent fingers and other objects from touching live circuits.
