Killark has a long-standing reputation as a trusted brand, and push buttons and signaling devices from this company deliver consistent results in critical applications across the USA and beyond. The operator types range from momentary to maintained to push-pull configurations. All allow for easy operation, even while wearing gloves, which is essential in heavy-duty industrial settings. The enclosures—most of which are made from stainless steel or copper-free aluminum—are rugged and reliable, and they are going to perform for years in unfriendly conditions. Whether for start/stop operation or process initiation, the inputs these switches provide are reliable and responsive.
More Information about Killark Push Buttons, Switches & Signaling Devices
At all times, it is critical for the operators to know what’s going on with their machine. Beyond visual signals, audible alerts like buzzers and horns can be used to enhance operator awareness and safety in large, noisy facilities. Operators in any kind of facility must be kept apprised of the most critical conditions. For that reason, signaling devices are often used to ensure any operator is informed of critical system changes, alarms, and fault detection indications. The most common audible signaling device is a horn or siren likely to be heard even in a loud facility. These devices emit a sound that carries over a long distance and can do so at a low decibel level that is easily heard.

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.
