We are engaged in manufacturing and exporting the premium quality Cam Rotary Switches. The Cam Rotary Switches, offered by us, are made by using the highest quality raw materials such as Plastic Granules, Non Ferrous And Ferrous Metals, Bakelite Powder and many others. Our team of engineers fabricates the Cam Rotary Switches as per the international quality standards. Moreover, we conduct stringent tests before delivering these Cam Rotary Switches to our clients for ensuring efficient performance. Moreover, our Cam Rotary Switches (10 Amps. to 63 Amps.) Programs nos. are available in both the models i.e. SDV-SE and SDV-PS. (DB)Sheet Steel Enclosure fitted with three Phase Selector Rotary Switches, R,Y,B Indicators and Bakelite Connectors available Upton 100 Amps.

Note : 100 Amp. is available in SDV-SE series only.

Features & Specifications
SE and PS Series rotary switches represent the most advanced rotary switches by Surdhi suitable for wide variety of applications. Switching versatility is available Phase to Phase, Phase to Neutral with off, Direct and CT operated to read voltage and Amperage for Voltmeter/Ammeter selector switches respectively. For reliability in performance switches are manufactured with the latest concepts in switching technology and are designed on On-Load basis, Surdhi SE and PS Series rotary switches are a turn for the better because they eliminate all the unnecessary completion in selection, ordering and application.

Surdhi SE and PS series rotary switches are stacked with add-on CAM and each CAM consists of contact block which are supported with the hexagonal center shaft. The quality of the insulting materials standards to with stand electrical and mechanical stress and has got an very high insulation resistance with good mechanical strength. For switching inside the CAM high grade silver contact tips are used to pass Electrical/Mechanical endurance test. Also for better making/breaking capacity of switching elements under normal/abnormal conditions stainless steel spring with appropriate tensile strength are used. According to different contact sequence & current rating different types of CAM are used.

For different purposes different kind of beautiful and elegant knobs/Handle with sharp and clear pointers are used.

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

Indicating Plate
Elegant and aesthetic indicating plates made of plastic are provided with attractive colour combination. Other colour combinations indicating plats are provided on request.
