SURDHI make Push Buttons, Selector Switches and Pilot Lamps are normally Suitable for Control & Auxiliary Circuits, AC or DC backed by thirty years of proven performance in the field.
These devices have contact reliability, increased operational safety, compactness and reduced labour input. These devices generally comply with the requirement of IS / IEC : 60947-5-1 : 2003. Push Buttons & Selector. Switches are available in Chrome Plated Metallic body.
The elements are interchangeable and can be stacked without additional hardware, 1 to 4 element (NO or NC) can be used with Push buttons and Selector Switches. For illuminated Push Buttons 1 or 2 element (NO or NC) may be used.
Indicating Lights with switching device and integral LED modules can be directly mounted on panel and rated voltage can be directly applied to the module input. These are available in Standard and barrel type enclosure in Thermoplastic housing for AC or DC Supply. We are counted among leading electrical control panel accessories exporters.
