<p>Snap action switches are highly sensitive switches that respond to very small movements and can rapidly change from one contact position to the other. The SE series are generally environment-sealed enclosed basic switches within a corrosion-resistant aluminum housing to seal precision switch contacts from contamination.</p><p>1SE1-2 Snap Action Switch from Honeywell has N.O./N.C. switch configuration and Single Pole Double Throw circuitry. With an operating force of 4.73 N and a release force of 1.11 N, this SPDT Limit Switch is used in many industrial and machinery applications to control electrical circuits.</p>
