Kraus & Naimer industrial rotary swtiches & Disconnect solutions

Kraus & Naimer

Kraus & Naimer rotary cam switches, disconnect switches & enclosed switches for industrial, marine & off-highway applications. Authorized distributor since 1957.

When industrial applications require robust switching solutions surviving harsh environments and heavy-duty operation, Kraus & Naimer provides rotary cam switches, disconnect switches, and load break switches engineered for reliability. We help facilties and equipment manufacturers select appropriate Kraus & Naimer switching technology matching application requirements.

Rotary Cam Switches

Industrial rotary switches for motor control, equipment control, and selector applications. Cam switches provide reliable multi-position switching in configurations from simple ON-OFF switches to complex multi-pole, multi-position selector switches with custom switching sequences.


Rotary switches providing manual motor control including DOL (Direct-On-Line) starting, reversing, and multi-speed control. Kraus & Naimer motor control switches handle motor starting inrush currents and provide reliable switching for industrial motor applications.

Rotary switches providing selection between multiple positions, functions, or control modes. Selector switches enable equipment with multiple operating modes, production recipe selection, and manual control sequence selection. Custom cam profiles create application-specific switching sequences.

Rotary switches transferring loads between power sources, control circuits, or equipment configurations. Changeover switches provide reliable switching in applications from generator transfer to motor winding changeover for multi-speed operation.

Disconnect Switches & Load Break Switches

Heavy-duty disconnect and load break switches providing safe equipment isolation for maintenance and emergency shutdown. Kraus & Naimer disconnects combine reliable load breaking capability with visible isolation ensuring safe equipment maintenance.


Combination disconnect switches and enclosures providing complete motor isolation solution. Enclosed disconnects provide NEMA-rated protection with visible blade position and door interlocking for safety compliance.

Heavy-duty switches capable of interrupting full load current under normal operating conditions. Load break capability enables switching motors and equipment without upstream circuit breaker operation. Kraus & Naimer load break switches provide reliable load interruption in industrial control applications.

Specialty & Application Specific Switches

Kraus & Naimer manufactures switches for specific industries and applications beyond general industrial use. These specialized products serve markets with unique requirements—marine, off-highway, hazardous locations, and clean room applications.


Switches specifically engineered for marine vessel applications meeting classification society requirements. Marine switches survive salt spray, humidity, vibration, and temperature cycling while maintaining reliable operation. Classification approvals from major marine societies enable use on commercial vessels.

Switches certified for use in explosive atmospheres where standard electrical equipment creates ignition hazards. Explosion-proof construction contains internal arcs preventing ignition of surrounding atmospheres. Various certifications enable use in different hazardous location classifications.

Switches for pharmaceutical, food processing, and cleanroom applications requiring easy cleaning, corrosion resistance, and contamination prevention. Stainless steel construction and smooth surfaces enable sanitation and meet FDA and pharmaceutical industry requirements.
