START WITH THE SWITCHING DUTY

Which function do you need?

The two series can look similar at a glance, but they solve different control and isolation tasks.

Recommended family

LW26 Rotary Cam Switch

Use LW26 when the required result depends on a defined switching angle, contact program or maintained and spring-return operating behavior.

APPLICATION ROUTING

Match the series to the equipment task

Application is the starting point. The exact current, voltage, contact duty and switching category still require circuit-level verification.

LW26

Control Panels & Instrument Selection

Choose meters, circuits or operating states through a defined contact program.

LW26

Machinery & Motor-Control Circuits

Use a configured switching program for control duties after the exact load and sequence are verified.

LW30

HVAC & Ventilation Equipment

Provide local switching and isolation for equipment service and maintenance workflows.

LW30

Pumps & Equipment Main Switching

Use as an equipment-level manual disconnect when the declared duty matches the installation.

ORDERING CHECK

Build a quote-ready switch specification

Send the information that changes the internal switching arrangement—not only the current rating.

TECHNICAL QUESTIONS

Rotary switch selection FAQ

Use these answers to shortlist a family, then verify the exact model against the circuit and installation.

What is the main difference between LW26 and LW30?

LW26 is a configurable rotary cam switch for selection, changeover and control sequences. LW30 is a load disconnect switch for equipment switching and isolation.

Can LW26 be selected by current rating alone?

No. The contact program, number of positions, switching angle, return behavior, voltage and load duty are also part of the selection.

Can LW30 be used as an equipment main switch?

It is intended for load switching and isolation duties, but the exact current, poles, voltage, utilization category, enclosure and applicable installation requirements must be confirmed.

What information should I send for a quotation?

Send the preferred series, current, voltage, poles or contact program, load type, switching positions, mounting, enclosure, quantity, destination market and OEM requirements.
