The 56SDP30-01-2-AJN is a single-deck rotary switch from Grayhill's Series 56, designed for industrial applications requiring compact panel-mount switching. It features a 0.5" diameter knob with a 200 mA contact rating at 115 Vac or 30 Vdc, and requires only 0.355" of space behind the panel, minimizing installation depth. The switch offers a 30° angle of throw with adjustable stop types to accommodate prototype and production requirements. Available in both PC-mount and solder-lug terminal configurations, it is rated for non-shorting (break-before-make) operation with resistive loads and supports up to 30,000 cycles at rated current. This economically priced switch is ideal for control panels, instrumentation, and industrial equipment where space constraints and reliable switching performance are critical.
