Full Surface Illumination (LTM2, LTMG2, LTR2 Series LTM 100m max Resistance Miniature, low-cost switch with full surface illumination by 1.5mA 200 VAC at 1.96N 200gf LED. Buttons available in square shape (7.5/10mm sq.) Dielectric Strength 250VAC 1 minute and round shape (7.5/10mm dia.) in 3 colors (Red, Green, 100M min 100VDC Insulation Resistance Yellow). Non-illuminated switches also available (LTM1, LTR 100,000 operations LTMG1, LTR1 series). Electrical Life LTM 300,000 operations 2. Two Types of Contacts LTR 3 msec. max. Initial value Contact Bounce LTR series: Conductive rubber contact for soft tactile feel. LTM 10 msec. max. Initial value LTM/LTMG series: Metal contact for sharp tactile feel. LTR 1 mm Travel 3. PC Board Mount LTM 0.25 mm Terminal pitch is in inches (multiples of 2.54 mm) for all LTR 0.98 0.39N Operating Force models. The unique terminal shape prevents the terminals at peak force LTM 1.37 0.39N Operating from coming loose from the PC board during dip soldering. 25 70 Temperature Range 4. Enhanced Resistance to Soldering Heat Storage 40 70 Temperature Range 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.
