Potentiometer V.R-3SW is a panel setting device for a maximum wattage ratting upto 3 watt with a micro NC / NO switch with maximum current rating upto 5A @ 230VAC- V.R-3SW has been specifically designed to have longer life, No discontinuity and smooth movement of shaft along with a additional feature to completely isolate the system from voltage entering the system.
- It has a feasibility to customize in several ways. Such as shaft modification, lug terminal arrangement, a vast range of ohmic value from 10 ohms to 100k ohms.
- The capability of the company to produce a vast range of ohmic value in potentiometer is a USP on its own.
- The Product can be made to Ingress protection upto IP65 and above on request.
- V.R-3SW has several other variants with model number V.R-3 (panel set potetniometer), V.R-3G (Ganged Potentiometer), V.R-3S (Endless Potentiometer), V.R 3CT (4 wire potentiometer),

Mounting Specification / Acessories
For best performance of V.R-3SW below points needs to be taken into consideration.
1) The hole in the panel should not be more than 9.5mm.
2) V.R-3SW should be mounted with Star washer given along with the product and perpendicularity between the panel and axis of potentiometer should be maintained.
3) For applications with extreme vibration please use lock nut assembly which is being supplied on the demand.
Operating Sequence
- From 0 to 54 degree the resistance between pin 1 and 2 and pin 3 and 2 will be infinite and switch will be in Normally
close mode - From 54 to 285 deg resistance between bin 1 and 2 will slowly increase from from 0 ohms to full range while the resistance between pin 3 and 2 will decrease from full range to 0 ohms
