Cam Operated Rotary Switches

JAIBALAJI Cam Operated Rotary Switches are in Great demand owing to their sophistication and the marks of ISI, CSA and CE. Manufactured on the basis of latest concepts in switching technology, JAIBALAJI switches are guaranteed for greater reliability in performance. Made to suit various circuits of multi-pole and multi positions, JAIBALAJI switches enable easy hand operation. JAIBALAJI Cam operated Rotary switches are designed for ONLOAD switching and assembled on add-n-block system and are used for various application.

Range

Switches are available up to12 positions with 30*, 45*, 60*, & 90* switching angles.

Instrument switches like Voltmeter/ Ammeter Selector switches are available phase to phase, phase to neutral with off or without off, Direct and through CT operated to read Voltage and Amperage respectively.

Range of products includes Phase Change over, Forward/ Reverse with single or Double Speed, Star Delta Switches for smooth change over and other motor control application.

These switches are available with sheet steel or aluminium housing.

Mounting

Two types of mounting plates for flush back of panel mounting are available with different dimension

Indicating plate

Elagant and aesthetic indiacting plates made of plastic are provided with attractive colour combination. Other colour combinations indicating plates are provided on request.

Specification

Cam Operated Rotary switches comply with IS 13947/Part5/Sec.1 of 1993 & JEC947-5-1 and carry unique ISI mark.

Cam Operated Rotary switches are certified by CSA International Canada, US and they conform to European standards

Temperature

Cam Operated Rotary switches are recommended for use up to 55* C ambient temperature, and they will withstand hot falling sand upto 300 * F

High Voltage

All switches withstand a test of 2.5 KV for one minute between phase and earth between terminals when the switch is off.

ConStruction

Cam operated Rotary switches are units of contact blocks assembled on add-on block system, support by a hexagonal operating centre shaft. High quality insulating materials are used to withstand Mechanical & Electrical stress and have excellent effective properties

Contact blocks are made of Engineering grade plastic to increase the life, insulations and mechanical strength.

Switches are provided with two independent sets of double break type contacts tips. For perfect making and breaking, stainless steel springs are provided.

Different types of Cams are used for different contact sequences.

Beautiful and sleek knobs or handles are provided for smoothy operation of making and breaking.
