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.

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.

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.


Accuracy Class- 1 or 0.5 
Over load-- Shunts are capable of with standing temperatures upto 120º C without any permanent alteration in physical or electrical properties. Over loads and faults which results in temperature of this magnitude can be safely handled.   
Temperature Co-efficient- 0.002% per degree centigrade, above ambient temperature in still air, with free ventilation, temperature not exceeding 120º C  at the centre and 90ºC at the ends.
Insulation- Shunts are supplied un-insulated and protection against contact should be installed where applicable.
Over loads (Brass Ended) - Continuous- 1.2 x Rated Current, 5 seconds- 4 x Rated Current upto 30 seconds,
5 seconds- 10 x Rated Current upto 5 seconds
Ambient Temperatures- Calibration -20ºC
 Working Range -20 ºC + 60 ºC


Compact Brass Ended- These shunts are often requested for special applications due to small size. Manufactured to IEC: 51 Class-1, they can be current rated from 5-50A with 25, 50, 60, 75, and 100mV output.
Standard Brass Ended- These Shunts are heavy duty type and provide accurate DC mili Volt signal suitable for measuring instruments and circuits and are manufactured as per IS: 1248, Class-1 or Class 0.5 with current rating from 5A- 15000A and 50- 300mV output.
Installation- For maximum heat dissipation, mount shunts in the horizontal manner, with the blade, standing vertical. Utilize the full end block surface area. Ample ventilation should be provided. Bus Bar should be adequately rated, clean and level, with a thin coat of silicon grease applied to the contact surface area. Use flat and tension washers under the nuts and tighten fully.


Current Transformers

“VAISHNO/HOTLINE/HOTLINE HOTLINE” Current Transformers reproduces proportionate primary current on its secondary side required for extending the range of the instruments or protective devices connected to its Secondary circuit.

Types Available : Tape Wound & Cast Resin Confirming to IS:2705
CORE: Toroidal core of high Permeability silicon steel.


METERING CT: Accuracy will be selected on the basis of the instrument i.e. when installed at a far away from CT the secondary is chosen as 1A instead of 5A.

PROTECTION CT: Meant for Circuit Breakers & Relays

When the ratio is low it becomes difficult to obtain good result with single & primary turn. For this both primary & secondary turns are wound on the toroidal core.

Rated Frequency - 5-60hz * Class of Insulation - E * Rated time thermal current ith - 60 in * Nominal surge current ldyn - 2.5 ith (minimum 100 kA at all window type Ct’s) * Highest voltage for equipment Um - 0.72Kv (other voltages on request) * Rated power-frequency withstand voltage - 4Kv / 1min (Other voltages on request) Instrument security factor - Fs5 or Fs10
