Grayhill 443491103N 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 have one or more momentary positions where maintaining contact requires rotational force; releasing the force returns the switch to a normal detent position. Available in various series (08, 09, 42, 44, 50) and configurations, these switches offer flexibility in design and functionality. They are suitable for a wide range of industrial applications where precise control and momentary action are needed.
