Description
SURAJ Rotary Switches are used to perform Make and Break operation in a sequential way by rotating the switch to different positions. The insulating disk material is High grade Polybutylene Terephthalate (PBT). PBT is an unbreakable, Non-Hygroscopic, High Insulating resistant and High Impulse Voltage withstanding material.
The electrical wiping contacts are made up of superior grade spring hard Phosphorous bronze. The terminals are made up from copper alloys for minimal transmission loss of electric current with low temperature rise which is within a specified allowed limits. The product range is from 16A to 125 Amps and can be customized to customers requirements.
