BEST 1W7B2 Electric High Security Key Switch Lock with SPDT Single Switch

The BEST 1W7B2 is a Grade 1 electric key switch lock with SPDT (Single Pole-Double Throw) maintained switch action, designed for high-security electrical control applications in commercial and institutional facilities. The double D lock cylinder prevents slipping and turning, screw terminals simplify field wiring, and the unit is UL recognized for use in demanding environments up to +176°F (+80°C). Compatible with BEST interchangeable core (IC) systems for unified key control across a facility.

Key Features

  • High Security Double D Cylinder: Prevents cylinder slipping and rotation - resists torque attacks common on standard key switches.
  • SPDT Maintained Switch Action: Single Pole-Double Throw configuration holds switch state after key is removed; supports both normally-open and normally-closed circuit legs simultaneously.
  • Heavy-Duty Contact Ratings: 15 A resistive at 125 VAC/VDC and 250 VAC; 0.6 A inductive at 125 VDC; 0.3 A at 250 VDC; 1/2 HP motor rating at 125-250 VAC.
  • High-Temperature Operation: Rated to +176°F (+80°C) - suitable for mechanical rooms, industrial panels, and unconditioned spaces.
  • Screw Terminal Wiring: Tool-accessible screw terminals accept standard wire gauges for clean, code-compliant field connections.
  • BEST IC Core Compatibility: Accepts BEST interchangeable cores (SFIC/LFIC) - swap cores without removing the lock body, enabling facility-wide key control.
  • UL Recognized Components: Meets UL electrical safety requirements for commercial switch applications.
  • Grade 1 Construction: Exceeds ANSI/BHMA Grade 1 durability standards for high-traffic commercial use.

Electrical Specifications

  • Switch Type: SPDT (Single Pole-Double Throw), maintained action
  • Contact Rating - AC Resistive: 15 A at 125 VAC; 15 A at 250 VAC
  • Contact Rating - DC Resistive/Inductive: 15 A resistive / 0.6 A inductive at 125 VDC; 0.3 A at 250 VDC
  • Motor Rating: 1/2 HP at 125-250 VAC
  • Operating Temperature: Up to +176°F (+80°C)
  • Wiring: Screw terminals
  • UL Recognition: Yes

Lock Specifications

  • Series: BEST 1W Series
  • Grade: ANSI/BHMA Grade 1
  • Cylinder: Double D high-security design; BEST IC core compatible (SFIC/LFIC)
  • Key Position: Position 2 - 12 o'clock

BEST 1W7B2626 – Frequently Asked Questions

1) Is the BEST 1W7B2 a door lock, or is it an electrical switch?
It is a key-operated electrical switch, not a door lock. The key turns switch contacts, not a latch or a bolt, and the unit lands in an enclosure or panel and gets wired with screw terminals to whatever it is controlling. That is why it is specified by contact rating (15 A resistive at 125 VAC and 250 VAC) rather than by backset or function code. Buyers put it on access control panels, machine enable/disable circuits, emergency system activation such as fire, HVAC and elevator recall, and equipment lockout at the panel. It carries a BEST cylinder so it keys into the same system as the doors, but the door hardware itself is a separate order.
2) Does the 1W7B2 key switch hold its position after the key is removed?
Maintained action, so it holds. The contacts stay where the last key turn left them, and only another key turn changes them back. Key position is position 2, 12 o'clock. That behavior is what makes it work for machine enable and disable, elevator recall, and locking out electrical equipment at the panel, where the state has to persist with nobody standing at the switch. If your circuit needs to make contact only while somebody holds the key over, a maintained switch is the wrong device for it.
3) What load can a BEST 1W7B2 key switch carry directly, and when do I need a relay?
On AC it is a real load switch: 15 A resistive at 125 VAC, 15 A at 250 VAC, and a 1/2 HP motor rating at 125 to 250 VAC, so a small motor or a resistive AC load can go straight through the contacts. DC resistive is also listed at 15 A at 125 VDC. Inductive DC is where it drops off, to 0.6 A at 125 VDC and 0.3 A at 250 VDC. Anything inductive beyond those figures, a bank of mag locks, a contactor coil, a large solenoid, should be switched through a relay or contactor with the key switch driving the coil instead of the load. Terminations are screw terminals, so it takes standard field wire.
4) Will the 1W7B2 key switch take the BEST cores we already use in the building?
It accepts BEST interchangeable cores, small format and large format both, so the switch goes onto the same keyway and the same master key hierarchy as every other BEST-cored opening in the facility. Cores pull and drop in without taking the switch body off the wall, which matters when a key walks off and a floor has to be rekeyed in an afternoon: the electrical connections stay untouched. For a facility standardizing on one key system, that keeps the control points, panels, machine disconnects and emergency switches, inside the same key control program as the doors.
5) Can I run a normally open circuit and a normally closed circuit off one BEST 1W key switch?
Yes, that is what the SPDT configuration buys you. Single pole, double throw means one key turn makes one leg while it breaks the other, giving a common, a normally open and a normally closed terminal off the single switch. Typical use is driving the controlled device on one leg while the other reports switch state back to a panel or holds an interlock. Wiring is at screw terminals, so all three legs land on standard field conductors with no harness or pigtail to splice.
6) Do I have to order the octagon box with the BEST 1W7B2, or can it go into an enclosure I already have?
Two ways to order it. Box option None gives you the key switch on its own, for mounting into the panel door, enclosure or box already on the wall. Box option OC1, the standard octagon, supplies the box with it for a new installation where there is nothing to mount into. Both choices are offered against every one of the nine finishes, so the box decision does not narrow your finish options.
7) Can a BEST 1W7B2 key switch go in a mechanical room or an unconditioned industrial space?
Operation is rated up to +176 F (+80 C), which covers mechanical rooms, rooftop equipment enclosures, industrial control panels and other spaces with no conditioning. The components are UL recognized for commercial switch applications, and the switch is built to Grade 1, heavy duty, so it is specified for the load and cycle demands of commercial and institutional service rather than light intermittent use.
8) How does the BEST 1W7B2 hold up if somebody puts a wrench on the key switch?
The cylinder is a double D high security design, which stops the cylinder slipping or rotating in the housing under torque. That is the failure mode on ordinary key switches: the cylinder spins in its hole and the circuit makes without a key ever being cut. Combined with Grade 1, heavy duty construction, it is the version to specify at exposed control points, a switch in a public corridor or on the outside of an equipment enclosure, rather than one behind a locked door.
9) What finishes does the BEST 1W7B2 key switch come in for matching existing hardware?
Nine finishes: 605 bright brass, 606 satin brass, 611 bright bronze, 612 satin bronze, 613 satin bronze oil-rubbed, 619 satin nickel, 625 bright chrome, 626 satin chrome, and 690 statuary dark bronze. Those are standard BHMA finish numbers, so if the lever sets and exit devices on the same floor were specified in 626 or 630-family satin work, matching the switch is a matter of ordering the same number rather than eyeballing it. Each finish is available with or without the OC1 octagon box.
