When working with CIT Relay & Switch products, it is crucial to follow proper soldering and cleaning guidelines to maintain product integrity.
While the terminal areas are epoxy-sealed to prevent flux wicking into the relay cavity, the covers, actuators, and bushings are not sealed. This means that exposing the switch to cleaning fluids, whether by immersion or spraying, could lead to contamination and potential damage.
Additionally, during soldering, flux vapors can settle on internal components, so good ventilation is recommended. If a cleaning process is required, care should be taken to ensure that the switches are not immersed or sprayed with any fluids or solutions.
