Grayhill 443451203N Spring Return Rotary Switch

Grayhill's spring return rotary switches are designed for applications requiring momentary positions, such as hold-to-test and hold-to-calibrate. These switches feature a spring mechanism that returns the contact to a detent position when force is released. They are available in multiple series (08, 09, 42, 44, 50) with various configurations, ratings, and circuitry options to suit diverse industrial needs. The switch's design allows for flexibility in application and offers a reliable solution for momentary contact requirements.
