Overview

Lauritz Knudsen Electrical & Automation Rotary switch designed to make and break operation by rotating the knob in different position and it ensures reliable.


This switch has a quick-make, quick-break mechanism with spring return functionality, and it ensures smooth and responsive operation.


Rotary switches offer versatile mounting options including standard panel, flush, and single-hole configurations, along with enhanced safety features like door interlocking, padlock provision, and lock & key mechanisms.

Isolators Switches

Isolators Switches

Isolators are ON-OFF Switches to isolate the power to a particular area of operation. Isolator Switch comes in a wide range from 1 Pole to 12 Poles. Isolators with spring return upto 4 Poles are available to energise circuits. Isolators with pre-close contacts are used for safety circuits and for connecting neutral and earth lines.

Changeover Switches

Changeover Switches

Changeover Switches also called Double Throw Switches are available with OFF and without OFF. These are used to operate two different circuits with different number of inputs and outputs. Changeover Switches without Jumpers (potential free contacts) are used to connect two different circuits from two different sources with two different operating voltages or any other incompatible lines.

Phase Changeover Switches

Phase Changeover Switches

Phase selector switches which allows the user to manually change the connection of the equipment to different phases, which can be useful for balancing loads, managing power distribution, or performing maintenance on electrical systems.

Breaker Control Switches

Breaker Control Switches

TNC switches are used for remote tripping and closing of circuit breakers. It has barrel lock option available with 1NO+1NO & 2NO+2NC option available in 25A

Ammeter and Voltmeter Selector Switches

Ammeter and Voltmeter Selector Switches

Ammeter/Voltmeter switches are used to measure currents/voltages in different circuit with a current Transformer

Multistep Switches

Multistep Switches

Multistep switches are also called as Pole-Way switches, they are available with OFF & without OFF. It does the function of connecting different circuits to a common supply or vice versa.1 pole, 2 pole & 3 pole are popular for 1 Ph, 2 Ph & 3 Ph supply.

Loadbreak Switches

Loadbreak Switches

Loadbreak switches has Double break contracts with polycarbonate shroud for wired terminal protection is included with excellent switching and high short circuit capacity. With outstanding electrical characteristics of loadbreak switches with compact design, it also contributes to space saving installation and operational convenience.
