˙Features
1. Full Surface Illumination (LTM2, LTMG2, LTR2 Series
Miniature, low-cost switch with full surface illumination by
LED. Buttons available in square shape (7.5/10mm sq.)
and round shape (7.5/10mm dia.) in 3 colors (Red, Green,
Yellow). Non-illuminated switches also available (LTM1,
LTMG1, LTR1 series).
2. Two Types of Contacts
LTR series: Conductive rubber contact for soft tactile feel.
LTM/LTMG series: Metal contact for sharp tactile feel.
3. PC Board Mount
Terminal pitch is in inches (multiples of 2.54 mm) for all
models. The unique terminal shape prevents the terminals
from coming loose from the PC board during dip soldering.
4. 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.
5. Compatible With Lead-Free Soldering (LTM Series)
Heat-resistance resin for lead-free soldering.
