The OMRON A6SN is a surface-mounting slide DIP switch, while the A6TN is a through-hole mounting version. They feature a knife-edge structure with a high contact pressure mechanism for high reliability. High pressure is generated by the actuator pushing the contact leaf which is made of hardening material. This mechanism also makes them washable even without seal tape. They come in a wide range of models from 1 to 10 poles, with both flat and raised actuators. The A6SN and A6TN can solder at exceptionally high temperatures – A6SN peak reflow temperature is +260°C, while A6TN peak flow temperature is +265°C.
