The use of slider resistors or ‘laboratory resistors” have been employed for over 50 years as a means of calibrating electrical and electronic devices. The can be configured in resistance bridge arrangements and provided the correct ratings are available, in high voltage test circuitry.

Slider Resistor Assembly

The single tube slider resistor range is often used in test laboratories where electrical and electronic components are required to be tested to ensure they meet Australian Standards. Examples of these are street lighting systems, traffic lights and transformers. Slider resistors provide for precision adjustment of resistance allowing accurate setup of voltage and current in test circuitry.
