Many Dwyer Instruments, Inc. switch products have standard snap-action switches. Snap-action switches have a mechanical movement that snaps the contacts together and apart to make or break an electrical circuit.
Silver contact snap switches are very versatile and offer high contact ratings commonly up to 10 or 15 amps when used with 120 volts AC. These switches are often used for control circuits with heavier load requirements such as pumps, motors, fans, and incandescent light bulbs.

Pressure transducers can be used in off-road equipment, construction machinery, performance racing, railroads, engines, and other applications where a transducer may be exposed to shock and vibrations. Transducers can be exposed to shock and vibrations through normal use, as well as during maintenance. Although not all applications subject a transducer to shock or vibrations, these devices tend to be very sensitive and their ability to accurately read pressure can be affected easily.

Every day, billions of gallons of wastewater are collected from our homes, businesses, and industries. Wastewater is exactly what it sounds like: water that has already been used and disposed of via a tub, toilet, sink, or storm drains. Because it is full of contaminants that make the water no longer suitable for use, it is collected in the sewer system and delivered to plants for treatment to make the water safe to be returned to the environment.
