Vibration-Resistant Plastic 22 mm Emergency
Stop Panel-Mount Push-Button Switches
A single-piece construction prevents the contact block from separating from the actuator in high-vibration applications. These switches immediately cut power with a single push. They have positive force contacts that will open a circuit when actuated even if a spring fails or the contacts stick. These switches meet American, Canadian, European, and other global safety requirements. They’re rated NEMA 4X, NEMA 13, and IP65 for protection from corrosion, washdowns, and oil/coolant spraying.
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.
Continuously illuminated switches stay lit once installed for high visibility in dark areas.

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 Relays
Unlike mechanical relays, these solid state relays have no moving parts, so they require less maintenance and last longer, switch faster, and are quieter. They mount on 35 mm DIN rail (also known as DIN 3) for fast installation. IP20 rated, their terminals are recessed, so they prevent fingers and other objects from touching live circuits.
Relays with an integrated fan are best for applications that generate more heat. The fan automatically turns on to provide additional cooling. When the temperature exceeds 176° F, an alarm sends a signal to an external device, such as a controller or indicating light.
