Foot Switches
Foot switches are a type of switch that is activated by the user's foot. They are commonly used in industrial and medical applications where hands-free operation is important. A foot switch can be designed with various specifications, such as maintained or momentary operation, and different types of contacts such as SPDT or DPDT.
The actuator of a foot switch is typically a pedal made of plastic or metal, and the switch body can be made of die-cast aluminum or other heavy-duty materials to withstand harsh environments. Some foot switches come with snap-action contacts for quick and reliable switching.
Foot switches are used in a variety of machinery and equipment, including industrial machines, medical devices, and process control equipment. They can also come with guards for added safety and protection.

Schneider Electric is a manufacturer that produces a variety of foot switches, including those with snap-action contacts and maintained or momentary operation. Their foot switches come in different series, sizes, and colors to provide users with a wide choice of products. Quick-connect or plug-in types are available to simplify installation and maintenance.
When selecting a foot switch, it is important to consider factors such as the application, required specifications, and size. Some foot switches are available in open or closed configurations and with different types of buttons. It is also essential to consider the necessary safety features to ensure that the user is protected from harm.
Maintaining NEMA 4 Rating When Making Enclosure Penetrations
Cutouts are very common when modifying enclosures for push buttons, indication lights, conduit entries or mounting hardware. Cutting into an enclosure runs the risk of eliminating the protective nature of the NEMA rated attributes. Proper steps must be followed in order to preserve the NEMA rating of an enclosure.
Devices mounted to the enclosure must have the same NEMA rating as the enclosure.
This means that if the devices are installed to the manufacturer's specifications, they will be able to maintain the NEMA rating of the enclosure.
Water tight conduit hubs must be used when running wire through a cutout in an enclosure.
There are many different types of conduit hubs that are used to secure conduit to an enclosure. However, only certain conduit hubs are rated for a watertight seal. By using water tight hubs, the NEMA rating of the enclosure is maintained.
Bonded washers are necessary when mounting hardware to an enclosure.
If standard mounting hardware is used, the NEMA rating of the enclosure will no longer be maintained. Bonded washers have rubber gaskets that make a watertight seal around the drilled hole. It is also important to make sure the material used for the bonded washer matches the material of the enclosure. Stainless steel enclosures require stainless steel bonded washers.
