Foot Switches
Keep your hands free for other tasks by triggering switches with your foot.
Back-pivot switches actuate with a tap of the toe. Optional guards prevent accidental switch actuation.

Circuit Board DC Magnetic-Object Proximity Switches
Send signals in response to changing magnetic fields to trigger processes or monitor position, speed, and current. These switches communicate with devices such as programmable logic controllers (PLCs) and microcontrollers. They’re also known as hall effect sensors. To install, push their contacts through holes in a circuit board, then solder them in place.
Momentary switches change their output signal based on whether a magnetic field is present. They’re often used to trigger a process in response to changing magnetic fields, such as turning on a light when a door opens. When they detect a north or south pole, they output a low-voltage signal. When they don’t detect a magnetic field at all, they output a high-voltage signal.

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. An LED indicator lights up when these relays are connected, so you can quickly confirm that they’re wired correctly. IP20 rated, their terminals are recessed, so they prevent fingers and other objects from touching live circuits.
Relays with an integrated heat sink disperse heat to increase the relay’s current rating.
