MHPS2285N is a momentary-action double-pole key switch designed for applications requiring reliable switching without audible feedback. It features non-shorting contacts and operates with a full travel of 2.5 mm and a lock travel of 1.5 mm, delivering an operating force of 180–450 grams. The switch is rated for 100 mA at 30 VDC with a contact resistance of 100 milliohms maximum and an insulation resistance of 100 megohms minimum at 500 VDC. With a minimum mechanical life of 10,000 cycles and an operating temperature range of -20°C to +65°C, this switch is well-suited for industrial control panels, instrumentation, and consumer electronics where silent, momentary switching is required.
