Grayhill M3786 13-0048 Rotary Switch

Grayhill M3786 13-0048 Rotary Switch is a Grayhill mechanical switch designed to route electrical connections within equipment. It is rated for 110 VAC and 28 VDC, confirming it can switch both mains-level AC signals and lower-voltage DC control paths in a single device. The M3786 model together with 13-0048 identifies the exact configuration within Grayhill’s rotary-switch lineup, aiding precise matching to compatible assemblies and control circuits. Rotary switches provide a manual, discrete method to change circuit paths or settings without rewiring, which can simplify maintenance and configuration tasks where multiple circuit options must be selectable by one actuator. With 110 VAC and 28 VDC ratings, this switch accommodates both AC power and DC control paths in environments that use mixed-voltage signaling.
