Control and Signaling Devices

SALIENT FEATURES

  • Very good flame resistance

 

  • Self wiping contacts ensure trouble free operation

 

  • Interchangeable blocks provide multiple contact configurations at site.

 

  • State-of-the-art workmanship aesthetic elegance

 

  • VAISHNO/HOTLINE Hotlines traditional hall mark for precision & exacting quality and assurance for consistency & reliability

 

  • VAISHNO/HOTLINE Hotlines more than two decades of trust and confidence

 

  • Safe in operation, locking device unaffected by vibration
  • Protection against electrical shock (Unit Earthed).

 

Push Buttons & 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 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.

The Pilot lights and illuminated switches are suitable for direct supply or supply through series resistor, using bayonet cap filament bulb type BA-9S for both AC/DC supply from 6V to 230V.

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 and AC or DC Supply.

SIGUT TERMINATION: This unique feature is highly user oriented. It increases safety to the user by preventing accidental contact by the user with live terminals.

COMPACT 22.5 mm DIAMETER: The smaller mounting diameter reduces mounting space by 30% as compared to conventional 30.5 mm design.

ENERGY SAVER: 22.5 mm devices require lamp with 2/2.6W instead of 7 to 10 watt lamps used in 30.5 mm devices. Thus results in energy saving.

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.

DC Shunts

VAISHNO/HOTLINE/HOTLINE HOTLINE DC SHUNTS are available for current ratings from 5A to 15000A with mV drops of 50-150 mV. DC Shunts are manufactured with Stringent Quality Control confirming to IS: 1248. Shunts consist of manganin rods/wire soldered or silver brazed to Brass/ Copper Blocks. The shunts are artificially aged after manufacturing, then tested on full load.

APPLICATION
Shunts are used for measuring current in DC Applications by connecting them to Moving Coil Panel meters, Digital Meters or other measuring devices. Shunts can also be used in Control Devices such as Power Supplies and Battery chargers or for over Load Protection.

 

TECHNICAL SPECIFICATIONS
