Microswithces Series Series 19N-3

This variant is available in two versions, fully sealed and top sealed. The top seal incorporates arubber seal around the button to stop the ingress of contaminants through this area. If the switch is to be activated by a cam, it would be advisable to do this via a lever, as using a cam directly onto the button can cause damage to the diaphragm seal.The fully sealed version has the top seal and also has integral leads pottedђ onto the terminals.This version is rated at 125C. There is also a derated version, to 105аC, available. This has the advantage of being lower cost than the standard version....
