VAISHNO CFG make Push Buttons, Selector Switches and Pilot Lamps are normally suitable for Control & Auxiliary circuits, A.C or D.C had been successfully proven performance in the field since 1979.
These devices have contact reliability, increased operational safety, compactness and reduced labour input. The availability of two separate models of contact blocks-rear wire connection type for panel mounting, application and front wire connection type for base mounted and other features make them as ideal choice for panel builders and machining tools etc.

Salient Features:

  • Excellent flame resistance.
  • Self wiping ensures trouble free operation.
  • Interchangeable blocks provide multiple contact configurations at site.
  • VAISHNO CFG hall mark for precision & exacting quality and assurance for consistency & reliability.
  • Safe in operation, locking device unaffected by vibration.
  • Protection against electrical shock.
Push button and selector switches are available in chrome plated metallic body and bezel as well as in glass filled thermo plastic body and bezel and are functionally interchangeable.

The elements are interchangeable and can be stacked without additional hardware, 1 to 4 element (NO + NC) can be used with push buttons and selector switches. For illuminated Push buttons 1 or 2 (NO + NC) be used.

The pilot lights and illuminated switches are suitable for direct supply or series resistor supply, using bayonet cap filament bulb type BA-9S and for both AC/DC supply ranges from 6V to 220V.

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 Thermoset (DMC) and Thermoplastic housing for AC/DC supply.
Compact 22.5mm Diameter: The small mounting diameter reduces mounting space by 30% as compared to conventional 30.5mm design.
Energy Saver:
22.5mm devices require lamp with 2/2.6W instead of 7 to 10W lamps used in 30.5mm devices. This results in energy saving.
