BEST 1W7B1626 – Frequently Asked Questions

1) Will the BEST 1W7B1 key switch work with the BEST interchangeable cores we already master key?
Yes. The 1W7B1 electric switch lock can be keyed into any BEST interchangeable core system, so it drops into an existing master key hierarchy rather than becoming a one-off key on the ring. That is the main reason a facility already standardized on BEST small format cores buys this switch instead of a generic key switch: the same maintenance key that opens the doors runs the switch.
2) Can a BEST 1W7B1 key switch directly switch a motor or a door operator, or does it need a relay?
The 1W7B1 is rated 15 amps at 125 VAC resistive and 15 amps at 250 VAC resistive, with a 1/2 HP horsepower rating at 125-250 VAC. Inside those numbers it can switch the load directly, including a small motor load such as an operator or fan. Above 1/2 HP or above 15 amps, run the switch into a contactor or relay and let that carry the load. Connections are screw terminals, so field wiring lands directly on the unit.
3) What does SPDT maintained action mean on a BEST 1W7B1 key switch, and when should I use momentary instead?
Maintained means the switch stays where the key leaves it. Turn it and the contacts hold that state until someone turns the key back, so it suits things you latch on and leave on: disabling an alarm zone, locking out a control panel, holding a door release, taking a machine out of service. SPDT gives you one common with a normally open and a normally closed leg, so the same key turn makes one circuit while breaking another. If your application needs a pulse instead, a signal that fires while the key is held and drops when released, a maintained switch is the wrong choice and you want a momentary version.
4) Which box do I order with a BEST 1W7B1 electric switch lock for an outdoor gate or an exposed exterior wall?
Five box choices are offered: SWR standard weather resistant, INT interior box, OC1 standard octagon, OC2 deep octagon, or None. For anything outdoors or exposed to weather, take the SWR weather resistant box. Indoors, the interior box or one of the octagon boxes suits a surface mount, with OC2 the deep octagon when the wiring behind the switch needs more room. Order None only when the switch is going into a box or panel cutout you already have.
5) Can a BEST 1W7B1 key switch go in a boiler room or a mechanical space that runs hot?
Rated for operation at temperatures up to +176 F (+80 C), so a mechanical room, a boiler space, or an equipment enclosure that runs hot is within its range. Construction is Grade 1 heavy duty and specified for commercial use, not residential trim duty.
6) What finishes does the BEST 1W7B1 key switch come in to match the rest of the hardware in the building?
Nine architectural finishes are offered on the 1W7B1: 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 matching the switch to the levers and exit devices already in the opening is a matter of ordering the same number, 626 with 626 satin chrome, 613 with oil-rubbed bronze trim.
7) Is the BEST 1W7B1 switch UL listed for use in a commercial control circuit?
All switches in the line are UL recognized or listed. Pair that with the 15 amp contact rating and the 1/2 HP motor rating when the electrical inspector or the spec engineer asks what the switch is qualified to carry.
8) Can one BEST 1W7B1 key switch both cut one circuit and make another at the same time?
Yes, and that is what the single pole double throw contact set is for. One key turn transfers the common between a normally closed leg and a normally open leg, so you can drop power to one device and energize another off a single key position, for example killing a machine circuit while signalling a monitoring panel that it was taken offline. It is one pole, so both legs share the same common; two independently switched circuits need a two-pole unit instead.
9) Why does the BEST 1W7B1 use a Double D cylinder instead of a standard round one?
The Double D cylinder shape keys the cylinder body to the switch housing so it cannot slip or spin inside the unit when someone puts torque on the key. On a keyed switch that matters more than on a lockset, because the whole point of attack is twisting the cylinder to throw the contacts without a key. This is a security detail, not a keying detail: the core itself still keys into the BEST interchangeable core system.
