Editing DPST

'''Double pole single throw''', or '''DPST''', refers to a switch that makes two connections simultaneously: two pairs of contacts are closed at the same time when the switch is pressed. One advantage of this design is reliability: should damage or oxidisation interfere with one pair of contacts, the other pair may remain functional, extending the life of the switch.

DPST microswitches typically take the form of a symmetrical slider with identical contacts on either side. The same slider may be used for both the [[SPST]] and DPST versions.

Numerous switch families were designed with DPST support, including many Cherry switch series.

DPST should not be confused with [[double action switch]]es, which contain two sets of contacts, but make the connections at different points in the force curve.
