Available in red or white in flush or surface and with or without an LED Indicator, they can help to keep engineers safe during routine testing and maintenance. Supplied with a plastic key and plastic key switch mechanism to reduce the risk of electric shocks, they have no exposed metal or conductive parts so no earthing is required. Fitted with a 5A high rupture capacity fast blow fuse, they feature a mechanically linked double pole switch to prevent the risk of contacts welding together and false isolated readings on LED variants.

Brian Foster, C-Tec’s UK Sales Manager, said: “Our new fire alarm mains isolator key switches are robust, reliable and very versatile. As with all our products, they are manufactured here in the UK at our multiple third-party certified facility to the highest quality standards. For additional assurance, all variants have been independently tested to the prime insulation and isolation requirements of IEC/EN 60669. They also have an optional branding label that allows them to be used on evacuation alert and emergency voice communication systems too.”
