Safety Switches
A safety switch is an electrical device used to disconnect power to equipment, machinery, and circuits for maintenance, servicing or emergency purposes. Safety switches are commonly applied at motors, HVAC systems, pumps, conveyors and industrial equipment, and provide a visible disconnecting means to help protect personnel from electrical hazards, while ensuring the safety of the electrical and safety codes.
Industrial safety switches are robust and rugged devices used in heavy-duty industrial applications. They are available in a wide variety of voltage and current ratings and have rugged metal or non-metallic enclosures that are suitable for use in indoor, outdoor, corrosive or washdown locations. Some versions are also provided with lockable handles and door interlocks for lockout/tagout (LOTO) requirements to ensure workplace safety.
Most safety switches are designed to meet NEMA and/or IP standards for use in hazardous locations or for applications where they are exposed to dust, water, chemicals, temperature, etc. Fused and non-fused versions are available along with options for visible blade disconnects, auxiliary contacts for remote monitoring, etc.

FAQs
What is the purpose of a safety switch?
A safety switch provides a safe, visible means to disconnect electrical power from equipment, helping protect workers during maintenance or emergency situations.
What is the difference between fused and non-fused safety switches?
Fused safety switches include fuses for overcurrent protection, while non-fused switches rely on upstream circuit protection such as breakers.
Are safety switches required by electrical codes?
Yes, electrical codes often require a local disconnecting means for motors and equipment, making safety switches a common compliance solution.
Can safety switches be used outdoors?
Many safety switches are designed for outdoor use and are available with weatherproof or corrosion-resistant enclosures rated for harsh environments.
Do safety switches support lockout/tagout procedures?
Most industrial safety switches feature lockable handles that support lockout/tagout practices, helping prevent accidental re-energization.
