LTR1 ~ 2 & ltm1 ~ 2 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 sq uare 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 fo r lead-free soldering. specications rating ltr 10ma 12vdc max. 10 a min. ltm 1va max. 50ma max.48vdc max 0.5ma min. ltmg 1va max. 50ma max.48vdc max. 10 a min. initial contact resistance ltr 500 max. 1ma 2vdc at 1.47n 150gf ? ltm 100m max 1.5ma 200 vac at 1.96n 200gf ? dielectric strength 250vac 1 minute * o t v m b u j p o 3 f t j t u b o d f 100m min yyyyyyyyy 100vdc & |
