Ultra-Miniature Illuminated Pushbutton Switches
FeaturesFeatures
-
Two Types of Contacts TR series: Conductive rubber contact for soft tactile feel. TM series: Metal contact for sharp tactile feel.
-
PC Board Mount Terminal pitch is in inches (multiples of 2.54 mm) for all models. The unique terminal shape prevents the terminal pins from coming loose from the PC board during dip soldering.
-
Enhanced Resistance to Soldering Heat Improved terminal structure protects the contacts from soldering heat. In addition, each pole has two terminals which can be used as a jumper wire.
-
Ultra-Miniature Switch with LED LED is built into miniature housing.
-
Wide Variety of Accessories A wide variety of accessories are available, including color buttons and mounting frames.

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.
| Series | TM | TR |
| Manual soldering | 380 ℃ Max. 3 sec. Max. |
380 ℃ Max. 3 sec. Max. |
| Auto soldering | 275 ℃ Max. 6 sec. Max. |
265 ℃ Max. 6 sec. Max. |
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.
