Push button switches are widely recognized and utilized devices that can be found in various applications around the world. When someone refers to a push button, they're typically talking about a simple switch mechanism that allows a user to control a function or action within a device or system. There are different types of pushbutton switches, such as momentary switches, which only remain actuated as long as the user is pressing them. Once released, these momentary switches revert to their original position. On the other hand, maintained push button switches stay in their actuated position even after the user has stopped pressing them, much like an "on-off" function.

In terms of electrical functionality, push button switches can be classified by the number of terminals and circuits they can control. For example, SPST (Single Pole Single Throw) is a type of push button switch that controls a single circuit. In contrast, SPDT (Single Pole Double Throw) can control two separate circuits but only has one actuated or "on" position. DPDT (Double Pole Double Throw) can control two circuits and has two actuated positions.

More Information about Push Button Switches

When it comes to choosing a push button switch for a specific application, one must consider the current and voltage ratings to ensure the switch can handle the electrical load it's intended for. Incorrectly matching a switch to an application can lead to malfunction or even damage.

The design of push button switches can range from small buttons used in handheld devices to larger buttons found on industrial panels. The panel-mounted buttons, for instance, typically come with terminals on the back to be connected to circuits. It's essential to understand the switch's functionality, whether it's momentary or maintained, to ensure it provides the desired outcome for its application.

Manufacturers produce a variety of push button switches to cater to different customer needs. From those used in everyday household items to those that find applications in complex machinery, push button switches are versatile and crucial components. With advancements over time, these switches have improved in quality, offering better performance and durability.

FAQs

What are latching push button switches?

Latching push button switches are used in applications where it is necessary to maintain a specific state until the button is pressed again. Unlike momentary switches, which revert to their default position once released, latching switches "latch" in their actuated state, effectively toggling between two positions with each press.

 

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.
