FSMRA3JH04 is a miniature push button switch designed for reliable switching in compact electronic assemblies. The switch features a maximum contact rating of 50 milliamps at 24V DC and a minimum contact rating of 10 microamps at 1V DC, with an initial contact resistance of 100 milliohms maximum. It incorporates a nylon 6/6 case in black, a steel frame with tin-over-nickel finish, and copper alloy contacts with silver plating for durability and low resistance. The switch operates over a temperature range of -35°C to +85°C with an actuation travel of 0.25 inches (±0.10 inches) and offers a life expectancy of 100,000 cycles. This switch is commonly used in control panels, instrumentation, and consumer electronics where space is limited and reliable momentary switching is required.
