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.

Other Details

Compact 22.5 mm Diameter : Our Product range in Control Panel Accessories are Led Indicators, Push Button, Contact elements, Illuminated Push Button, Selector Switches, Emergency Stop, Mushroom Actuators, Key Mushroom and Key selector Actuators, Led Pilot Lights and many more. We are able to build any customised items in this DIA 22.5mm categories.
Mounting : Only screw driver is required for fixing these devices on to panel having thickness of 1 to 6 mm in any position. The whole assembly is locked into position with the help of two M4 pointed screw on the bracket. These screws also ensure the earthing. We recommend fixing centers as per standard. The Screws should be tightened simultaneously to an extent as to pierce through the paint on the panel from inside.
