Emergency Red Stop Switch

An Emergency Red Stop Switch is a specialized safety component engineered to swiftly shut down risky equipment (such as conveyors, power tools, or automated production lines) when emergencies occur—its vivid red color (compliant with global safety norms like ISO 13850) serves as an immediate visual cue, ensuring operators can locate and activate it in milliseconds to avoid injuries or equipment damage.

A key specification here is the 19mm cut-out size—this denotes the diameter of the circular mounting hole needed in control panels or machine casings. Smaller than the common 22mm standard, the 19mm size is ideal for compact equipment or control panels with limited space (e.g., small-scale robotics, portable industrial tools, or tight machine enclosures). It maintains usability: even with its smaller footprint, the switch’s actuator is designed to be accessible, allowing activation with or without gloves in fast-paced work environments.

The metal material of this switch elevates its performance and durability significantly. Unlike plastic alternatives, metal (often aluminum alloy or stainless steel) resists high impacts, extreme temperatures (ranging from -20°C to 80°C in most models), and chemical corrosion—critical for harsh settings like automotive assembly lines, metalworking shops, or outdoor construction sites. It also offers enhanced structural stability, preventing deformation from repeated use or accidental knocks. Most 19mm metal Emergency Red Stop Switches feature an IP65/IP66 ingress protection rating, shielding against dust and water splashes, while their "mushroom-head" design enables tactile recognition and requires a twist-or-pull reset (to avoid accidental restart). Additionally, their normally closed fail-safe contacts ensure that if the switch malfunctions, the emergency stop function remains active, upholding maximum safety.
