■Features
1. Two Types of Contacts
TR series: Conductive rubber contact for soft tactile feel.
TM series: Metal contact for sharp tactile feel.
2. 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.
Insulation resistance

3. 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.
4. Ultra-Miniature Switch with LED
LED is built into miniature housing.
