DESCRIPTION

DPS9131AK is a dual pushbutton code switch from the DPS9 series designed for front-mount applications with BCD (Binary Coded Decimal) encoding and PCB short terminal connections. The switch features a width of 0.315 inches per section, gold-clad wiping contacts rated at 0.4 VA @ 20 VDC with a maximum contact resistance of 0.20 Ohm, and a mechanical life exceeding 1 million operations. It operates with an approximate force of 16 oz and functions reliably across a temperature range of -20°C to +80°C, with a dust-sealed window protecting the wheel markings. The DPS9131AK is ideal for applications requiring silent, bi-directional operation and can directly retrofit common thumbwheel switches, making it suitable for instrumentation panels, control systems, and equipment requiring reliable numerical input selection.
