It's a single pole switch with connections exactly as in the photograph.
A lot of these switches look similar, but the pin position and configuration are different as is the switch action depression distance. Thus some switches will not operate correctly, if they are used in incorrect machines.
SAFETY WARNING! All electrical parts should ONLY be fitted by an electrically COMPETENT person.
