Product Overview
Manufactured by MICRO SWITCH in Freeport, Illinois, part number MS25008-1 (catalog listing DT-2R-A7) provides simultaneous two-pole double-throw switching via an integral top pin plunger. Built to military standard MS25008-1, this snap-action basic switch controls two separate circuits through independent normally open and normally closed contact sets. Six round-head 4-40 screw terminals with lock washers are mounted across the base, separated by a central woven fiber insulating barrier.
Key Features
- DPDT circuitry providing two electrically isolated SPDT contact sets operated by a common actuator
- Top-mounted in-line pin plunger actuator
- Electrical rating: 10 A at 125 or 250 VAC, 0.3 A at 125 VDC, 0.15 A at 250 VDC
- Six 4-40 screw terminals with split lock washers
- Yellow woven insulating separator clearly marked N.O., C., and N.C.
- Heavy-duty black phenolic housing with dual side through-holes for chassis mounting
- Standards compliance: MS25008-1 military standard, UL recognized, CSA certified
Applications
- Replacing worn interlock or limit switches on legacy machine tools, punch presses, and packaging equipment
- Servicing ground-support test consoles and military-specification avionics panels requiring an exact MS25008-1 replacement
- Wiring dual-circuit reversing mechanisms and redundant safety cutoffs in custom shop automation
- Building heavy-duty benchtop test fixtures and foot-pedal controls that demand positive snap-action feedback
Frequently Asked Questions
What are the voltage and current ratings stamped on this switch?
The housing is factory marked for 10 A at 125 or 250 VAC, 0.3 A at 125 VDC, and 0.15 A at 250 VDC.
How are the two circuits isolated on the terminal block?
The switch features two parallel rows of three screw terminals separated by a central yellow insulating barrier. Each side provides one Common, one Normally Open, and one Normally Closed connection.
Why purchase this specific switch instead of an uninspected surplus lot?
You receive the exact switch documented here with legible Freeport markings and clean terminal hardware, without buying an unknown multi-pack just to find one functional unit. This item clears the free shipping threshold on its own, and orders leave our Idaho warehouse the same or next business day.
Built in Freeport back when industrial switches had solid phenolic bodies and a mechanical click you could feel through heavy work gloves. Wire it up, tighten down the terminal screws, and put your equipment back into action.
