Katko is a Finnish family business specialising in safety switches, load break switches and fused switches with more than 70 years of experience. Not all safety and load break switches on the market come from specialised manufacturers by any means, and that is precisely why we are so proud of ours. We design and manufacture every product ourselves in our own factories. The challenging Finnish climate creates a basis for developing switches that work in all conditions across the globe. Switches without compromises. This is what we at Katko think, as did the generations before us.
