ajn1, 2 super-miniature operation switches turquoise snap switches (ajn1/2) features 1. designed to be as compatible as possible with other switches. as shown in the table below this switch is compatible with both the toggle and push-button switches of other companies. remark: c: compatible; n/c: not compatible 2. hermetically sealed for superior resistance against adverse environments (dust and gas) and washing protective grade: the body is hermetically sealed to the level of ip67 so it can be washed as is (except terminals). also, there will be no problem when using a standard substitute freon cleaning solution. (for details, please inquire.) 3. low level rating of 0.1?, 1 mv achieved. sliding contacts on both sides are used to ensure high contact reliability. 4. resistance to static electricity of up to 20 kv at the lever tip the operation lever is made with resin to prevent entry of static electricity into the signal circuit. however, 10 kv at the lever tip for bracket types 5. long electrical and mechanical life achieved. electrical: min. 100,000 times (0.4 va) mechanical: min. 200,000 times 6. all models use pc board independent terminals press ?ting is possible to pc board using only light force and the ?ing force prevents the switch from rising. 7. lead free compatibility. construction applications of?e automation equipment (personal computers, printers, etc.), large-scale computers, walky-talkies, professional video cameras, switching equipment, electrical measuring instruments, and control panels (robots, sequencers, elevators, etc.). mew other company ? company ? company a series b series a series 1 p 2 p pc board terminal c c n/c bracket type c n/c n/c pc-h terminal 0.2 inch pitch type ccc 0.3 inch pitch type ?c pc-v terminal c n/c n/c rohs directive compatibility information http://www.nais-e.com/ contact movement as seen from directly above fixed terminal dual-side sliding contacts dual-side sliding contacts (au plating on contact part) fixed terminal (au plating on contact part) reinforced resin lever anti-static electricity property of at least 20 kv realized. sealed with o-ring. higher level than ip67. highly reliable dual-side sliding contacts 0.1 a, 1 mv realized pc board independent terminals automatic solder rising prevention te r minal area is sealed with epoxy resin. all rights rese r v ed c o p y r i gh t matsushita elect r ic w o r k s , ltd.
