EATON 10250T line of 30.5 mm pushbuttons features a heavy duty zinc die-cast construction. Reliability nibs improve contact reliability even under dry circuit and fine dust conditions. In addition, drainage holes prevent the build-up of liquid inside the operator, which can prevent operation in freezing environments.
