1/4 DIN Rotary 'Jab-In' Selector Switches for Thermocouple, RTD and Thermistor Circuits

Fits Standard 1/4 DIN Cutout
Gold or Silver Plated Contacts
2, 3, or 4 Poles
2 to 34 Positions
Round or Pistol Grip Handles
For isothermal, low resistance switching of temperature measurement circuits, OMEGA offers the SW14 1/4 DIN switches with gold or silver-plated contacts. Each style offers 2 to 40 positions in a break-resistant Noryl case. They are available with break before make and make before break contact action, in 2, 3 or 4 pole versions. They come with the standard round knob or optional pistol grip handle.
The isothermal design of these rotary switches minimises temperature gradients between the input and output thermocouple wiring. This in turn minimises errors in transmitting thermocouple signals due to the generation of a thermal emf at the wire junctions. The low resistance of the silver or gold plated contacts also enables switching of temperature sensitive resistance devices, such as RTDs and thermistors.
