The 5237YCDBX445 is a single-pole, momentary (MOM-OFF-MOM) miniature toggle switch from the 5000 series, designed for PCB mounting. It features gold-plated brass contacts rated for a maximum of 0.4 VA at 20 VAC or DC, making it suitable for low-level switching. The switch is configured with epoxy-sealed straight PC terminals and a short mounting bracket, and includes the X445 special option, which specifies a plain bushing with a height of 7.2 mm. Due to its momentary action and reliable contacts, this toggle switch is well-suited for applications in instrumentation, telecommunications, and control panels where temporary signal inputs are required.
