Katko Fireman Switch

"A fireman switch is a critical safety component used to isolate power to high-voltage neon signs and other exterior electrical installations in the event of an emergency. At Demesne Electrical, we are the leading stockists of the Katko Fireman Switch range, specifically engineered to provide firefighters with a safe and rapid means of disconnecting power before entering a fire zone. These switches are mandatory for many commercial buildings to comply with standard electrical safety regulations and insurance requirements.

Why Choose the Katko Fireman Switch?

The Katko range stands out in the industry due to its specialized reverse operation mechanism. Unlike standard electrical switches, the "OFF" position is located at the top. This design is intentional: it allows a firefighter to quickly strike the handle downwards with an axe or heavy tool to instantly isolate the circuit.

Our Katko switches feature robust housings, typically available in die-cast aluminium or high-impact polycarbonate, ensuring they can withstand the harsh environmental conditions of an Irish winter. With an IP66 rating, these units offer complete protection against dust and high-pressure water jets, making them ideal for exterior mounting on shopfronts and industrial sites.

Reliable Construction for Critical Safety
Safety is at the core of the Katko design. The units are built with a mechanical interlock to prevent the cover from being removed while the switch is in the "ON" position, ensuring maintenance is carried out safely. To complete your installation, explore our range of SWA cable glands and high-quality cables to ensure secure connectivity.

Whether you are looking for a compact 16A model or a high-capacity 25A unit, our Isolators and Switch Fuses category provides versatile options. For systems requiring clear identification, we also stock cable markers and labels to assist in emergency identification."
