LTR1

Ultra-Miniature Illuminated

Pushbutton Switches

RoHS Compliant

■Series

Conductive Rubber Contact

（LTR type）

Mettal Contact

（LTM type）

■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.
