The 48BFSP1M2RT is a Series 48B sub-miniature slide switch featuring SPDT (Single Pole Double Throw) circuitry with momentary operation and M2 termination. It delivers a contact rating of 3A at 125 VAC or 28 VDC (Q option) with a maximum contact resistance of 10 milliohms and an insulation resistance of 1,000 megaohms minimum. The switch operates reliably over a temperature range of -30°C to 85°C with an electrical life of 30,000 make-and-break cycles at full load, and features a dielectric strength of 1,000 V RMS. The housing is constructed from stainless steel with a nylon switch handle and copper alloy contacts with gold or silver plating, sealed with epoxy for durability. This compact design is ideal for space-constrained applications requiring reliable switching performance in industrial, telecommunications, and consumer electronics equipment.
