EDSAC1LFS is a momentary-action tactile switch featuring a disc dome contact element designed for reliable switching in electronic applications. It delivers an operating force of 2.4 N (240 grams) with ±25% tolerance, a short travel distance of 0.3 mm ±0.15, and tactile feedback of =25%, providing responsive user interaction. The switch operates at voltages up to 100 VDC with a maximum current rating of 100 mA, contact resistance =100 mO, and an operating life of 1,000,000 cycles. It features through-hole PCB terminations with silver plating (RoHS-compliant lead-free compatible), operates across a temperature range of -25°C to 85°C, and exhibits a bounce time of =3 ms. This switch is ideal for aircraft panels, instrument controls, and radio equipment where compact size, reliable tactile feedback, and long operational life are essential.
