Steel Push Button Enclosures

Push button enclosures are designed to work with 22.5 mm or 30 mm push buttons, switches, pilot lights and other indicators. They can have 1 to 42 holes to house illuminated and non-illuminated control and indication devices and are made in steel, stainless steel and non-metallic material. They can be rated for indoor or outdoor use. Push buttons are mechanical switches that open or close one or more circuits to control an aspect of a machine or process.
Push button switches are typically used to start or stop a process, with the switch being in a normally-opened or a normally-closed position. An indication light can be included in the push button to show the state of the switch. Selector switches are mechanical switches that open or close electrical contacts by rotating the handle right, left or center. These switches normally come in 2-position or 3-position options and with or without keys. Some indication and signaling devices give an audible or visual indication of the status of a situation that needs attention. Examples include: beacons, buzzers, pilot lights, signal towers, sounder horns and strobes.

Before mounting to any surface, it is important to understand how the hardware will interface with the enclosure. In many cases, the enclosures will have holes at the corners that can be used to attach any mounting hardware. It is common to see a mounting strut, commonly referring to as a Unistrut, being used with these electrical enclosures. The Unistrut can attach to the enclosure and provide a very strong connection point to either a wall, concrete or pole mount.
When mounting to a concrete wall, there are several things that should be considered to ensure it is done correctly. Industrial concrete anchors provide a very strong and reliable connection that can last a very long time. Make sure that the concrete is thick and strong enough for these types of anchors. Once the anchors have been installed, attach them to the mounting strut that is attached to the enclosure using hardware that is designed for that particular type of mounting strut.
When installing an electrical enclosure on a pole or mass, it is important to make sure that the pole can handle the weight of the enclosure. It is recommended that the pole is made of a very strong rigid material. At least two inch rigid galvanized conduit is recommended. Once the pole has been secured into the ground, strut clamps designed for the size of conduit will attach the enclosure.
