Handling Notes

Ambient Conditions

• In case of switches with silver-plated contacts, do not use in an environment where there is corrosive gas such as sulfuric or ammonia gas which may affect the silver plating.
• TM and TR series are open-structure switches and should not be used in a dusty environment.

Soldering Specifications

• Preheating in the flow line should be 80 °C to 120 °C and within 120 seconds.
• Do not dip solder the switches with color buttons or mounting frames attached. Soldering heat may deform the accessories or cause ingress of flux.

Flux Cleaning

• Solvents : Fluorine or Alcohl type
• The TM/TR series are not washable. To wash the PC board, clean the soldering surface of the PC board with a brush so that the switch is not exposed to the cleaning solution.
• After soldering, wait until the temperature of the terminals cool down to 90℃ or below or until the parts are exposed to room temperature for more than 5 min. before washing.
