The 093111-4-03N is a spring return rotary switch designed for special function applications including hold-to-test, hold-to-calibrate, and other momentary control scenarios. This switch features 4 decks with non-shorting contacts and 3 positions per pole, providing reliable momentary operation that requires rotational force to maintain contact at momentary positions. The switch is rated for 10,000 cycles of operation and has a 30° angle of throw, with a dimension A of 1.764 inches (44.81 mm) and dimension B of 0.062 inches (1.57 mm) stud projection. The spring mechanism automatically returns the contact to a normal detent position when rotational force is released, making it ideal for instrumentation, calibration systems, and test equipment where momentary switching is required.
