NOTE: Snap switch contains two electrically separated sets of contact
elements allowing use on circuits of opposite polarity. Each set
contains two double break contact elements (1 N.O. and 1 N.C.) that
must be used on circuits of the same polarity.

(600 Vdc rating does not apply)
NOTE: Contacts are single pole, double throw—one circuit
normally open and one circuit normally closed. These circuits
are not electrically separate and can not be used on opposite
polarities.
