The A Series is a family of process-sealed subminiature toggle switches designed for low-voltage, low-current logic-level circuits. These switches feature a totally sealed body to prevent contamination and support automated soldering and cleaning. They have a 2.54mm x 2.54mm terminal spacing compatible with standard PCB grids, and offer PC board mounting options including straight, right angle, and vertical orientations. Electrical ratings include a maximum resistive load of 0.4VA at 28V AC/DC, contact resistance of 50 milliohms maximum, and insulation resistance of 500 megohms minimum. The switches operate within a temperature range of -30°C to +85°C and meet mechanical life requirements of up to 100,000 operations for ON-NONE-ON and ON-OFF-ON circuits. The toggle actuator employs an STC contact mechanism for positive detent actuation and enhanced reliability.
