An inductive fixture switch for INGUN MA 3xxx manual test fixtures. Inductive sensing detects the pressure frame's position without physical contact, so there is no mechanical actuator to wear, no contact bounce, and nothing to drift out of adjustment as the fixture accumulates cycles.
The switch reports where the frame is — open, or closed and contacting — so a test run can be gated on the DUT genuinely being clamped rather than on an operator pressing start. That matters most on exactly the kind of large, high-throughput fixture the MA 3xxx series is built for, where a mis-seated board wastes a long test cycle.
This is the MA 3xxx variant; the equivalent switch for the smaller MA 2xxx series is stocked separately. Check the fixture's frame size before ordering — the two are not interchangeable.
