Specialized Control with Single-Sided Momentary Action

The Pollak 34-578 is a unique Double Pole Double Throw (DPDT) switch designed for specific industrial and automotive tasks. It features a (On)-Off-On configuration, providing one Momentary-On position that springs back to center, and one Maintained-On position that stays locked in place. This setup is ideal for equipment requiring both a constant-run mode and a temporary "jog" or "override" function.

The 6 screw terminals (#8-32) are riveted to a durable Bakelite base, ensuring your wiring stays secure even on the roughest roads.
