Benshaw Push Buttons, Switches & Signaling Devices
Benshaw push buttons and signaling devices are built for industrial control applications where durability, performance, and safety are essential. These devices make the operator interface between humans and machinery possible, allowing for the precise control of motors, automation systems, and process equipment.
Each push button is made of high-quality materials and is designed to withstand the heavy-duty operation demanded of it in an industrial facility. Benshaw's focus on a rugged design means that its push buttons, switches, and other control components deliver a long service life with reliable functionality when mounted in any panel or control enclosure.
Push buttons are a basic control component that Benshaw makes in a variety of configurations—including maintained, momentary, illuminated, and emergency-stop designs. A 30mm push button has a clamp ring that makes for easy NEMA sealing. Benshaw also makes pilot lights, signal towers, beacons, buzzers, strobes and horns which provide visual and audible indications as to the status of equipment in industrial settings.
FAQs
What environments are Benshaw push buttons, switches and signaling devices designed for?
These products are built to perform in industrial applications and are rated for environments requiring durable control components, including NEMA 4X enclosures and heavy-duty usage.
What sizes are available for Benshaw push buttons?
Benshaw offers 30 mm push buttons in maintained or momentary versions, illuminated or non-illuminated, with black polyester clamp ring NEMA 4X construction for harsh-environment installation.
What ratings do Benshaw push buttons, switches and signaling devices have?
Many devices are UL listed, designed for NEMA 4X protection, and specified for industrial resistance to dust, moisture and mechanical stress suitable for machine control environments.
How do I replace a contact block or switch module?
Benshaw devices support field configurable options, installation must follow the manufacturer’s instructions to maintain ratings.
What is the ideal Benshaw pilot device when rotating is required?
The ideal Benshaw pilot device when rotating is required is a selector switch, which allows multi-position control for operating or selecting machine functions with a turning motion.
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.
