Resistance value R should be calculated using the formula on the right. Accessories mounting 1.Installing the mounting frame Install the mounting frame so that the tab on the frame is in the same direction as the slot on the switch. R= EVF IF R= 52.0 0.02 =150 Use VF=2.0V to calculate. 2.Installing the button Install the button so that the recess on the button is in the same direction as the protruding portion on the switch. The mounting frame cannot be installed with the switch button installed. 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 Flux Cleaning Series Manual soldering Auto soldering TM TR 380 Max. 3sec. Max. 275 Max. 6sec. Max. 380 Max. 3sec. Max. 265 Max. 6sec. Max. 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. 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.
