Micro Switch with Arm Details Description
The MQS-421BE02-AG01 micro switch with arm is a miniature waterproof Microswitch with IP67 protection level. And the circuit for this model is SPDT which means the switch has a “single pole and double throw”. I mean this can control 2 circuits in switching, one of them connecting the COM and NC, and another one controlling the COM and NO. Meanwhile, because of its small size and waterproof function, our switch can be used in most automotive parts and electric tools.
