Electro-Mech Series S570 is a compact, snap-action DPDT (or 4PDT) switch with an independent lamp circuit. The switch series is available in both 2 Form C (DPDT) or 4 Form C (4PDT) versions which are ideal for reliable power circuit operation where snap- action switching is preferred. The S570 is a rugged switch (designed to meet Mil-PRF-22885) that has been increasingly applied in the most demanding commercial and industrial applica- tions. This product series was formerly manufacturing by Pendar/General Instruments/Pollak Pendar Switchlight Division.
