DESCRIPTION

M3786/36-0239 is a military-qualified multi-deck rotary switch from Grayhill's Series 53, 57, and 59 line, designed for applications requiring high reliability and compact form factor. The switch features a 1.125" diameter with 1/4 amp current capacity and employs a gold-plated contact system compatible with logic circuitry, meeting MIL-DTL-3786/36 specifications. It is constructed from military-grade materials including stainless steel shafts, brass gold-plated terminals, and silicone rubber seals, with shaft and panel sealing via O-rings for environmental protection. The switch supports multiple deck configurations (up to 12 decks), variable pole counts (1 to 8 poles per deck), and position ranges (2 to 24 positions depending on series), with contact resistance of 50 milliohms maximum and insulation resistance of 1,000 megohms minimum. It meets demanding environmental requirements including thermal shock (-65°C to 125°C), salt spray, vibration (10 to 500 cps), and high shock conditions. These switches are ideal for military, aerospace, and industrial control applications where durability, precision switching, and compliance with military standards are essential.
