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.

Many Dwyer Instruments, Inc. electrical products are connected to the receiver and power supply with wires that are run through electrical conduits. Often, the conduit passes through multiple ambient temperature zones in the building or plant installation.
These temperature changes can cause water vapor condensation inside the conduit.
If this condensation flows into or forms in the instrument, it can create electrical shorts or lead to corrosion that can create an instrument failure. Continue reading “Condensation Issues in Instrumentation Enclosures and How to Prevent Them”
The Proximity Controls Division of Dwyer Instruments, Inc. specializes in both bulk level monitoring and valve position indication. Rarely do these two sides of the business intersect. That is until the engineers at Proximity Controls came across a challenge to improve an industry standard level sensing technology. Continue reading “Rotary Paddle Level Switches Re-Invented”
