BEST 1W7R4626 – Frequently Asked Questions

1) Can the BEST 1W7R4 switch lock be used with our existing BEST interchangeable core master key system?
Yes. The 1W7R4 takes any BEST interchangeable core, so it drops into an existing BEST keyway and master key system without adding a separate key to the ring. The cylinder uses a double D design that keeps the core from slipping or turning in the housing under repeated operation. For a facility already standardized on BEST cores, that means the electrician installs the switch lock and the locksmith pins and drops the core the same way as on every other opening.
2) What does the momentary action on the BEST 1W7R4 mean for how the key behaves?
Momentary means spring return. Turn the key and the circuit changes state only while you hold it; release and the switch springs back to its rest position. Key positions sit at 2 o'clock and 10 o'clock. That behavior is what you want for a start pulse, a reset, or an emergency stop reset circuit, where you do not want a technician to be able to walk away leaving the circuit latched. If your application needs the circuit to stay switched after the key is released, a momentary unit is the wrong choice and you want a maintained action switch lock instead.
3) How many circuits can a BEST 1W7R4 switch lock control at once?
Four. The 1W7R4 carries four SPDT (single pole, double throw) switches operated together by one key. Each SPDT gives you a common, a normally open and a normally closed contact, so a single key turn can make one circuit and break another across four independent circuits at the same time. That is the configuration to specify when one key action has to kill a motor circuit, signal a PLC, light an indicator, and drop an interlock simultaneously. If you only need one or two circuits, a smaller switch count in the same family is the cheaper specification.
4) Will a BEST 1W7R4 handle a 15 amp motor load, and what are the contact ratings?
The 1W7R4 switches are rated 15 amps at 125 VAC resistive, 15 amps at 250 VAC resistive, and 15 amps at 30 VDC resistive, with a 1/2 HP rating at 125 to 250 VAC for motor loads. Note the difference: the 15 amp figures are resistive ratings, and inductive motor loads are governed by the 1/2 HP number, not the 15 amps. Size the branch circuit and conductors to the 15 amp application load. Switching a larger motor means putting this lock on the coil of a contactor rather than in the motor circuit itself.
5) Do I need to order a box with the BEST 1W7R4, and what does the SWR option get me?
Two box choices are offered on the 1W7R4. Ordering with Box Option None gives you the switch lock alone, for mounting into a panel door or an enclosure you already have. The SWR option supplies a standard weather resistant box, which is what to specify for exterior gate controls, loading docks, or any wash down or unconditioned location. Pick the box before you pick the finish, because both choices are available across the whole finish range.
6) Is the BEST 1W7R4 a door lock, or does it go on a panel?
It is a key operated electrical switch, not a latching door lock. The 1W7R4 has no bolt and no latch; turning the key throws four sets of electrical contacts. Its job is to put a keyed, master keyable barrier in front of a circuit, control panel security, machine access control, lockout tagout points, emergency stop reset, and motor control center access. If you are securing a door leaf, you want a bored or mortise lockset instead.
7) How hot can the environment get around a BEST 1W7R4 switch lock?
Operating temperature runs up to +176 degrees F (+80 degrees C), which covers boiler rooms, rooftop mechanical, motor control centers and most industrial process areas without derating. That upper limit is the deciding number when the lock is going on an enclosure that sits next to heat producing equipment.
8) Is the BEST 1W7R4 switch lock UL recognized, and is it rated for commercial use?
All switches in the 1W7R4 are UL recognized or listed. The unit is Grade 1, heavy duty, and specified for commercial rather than residential use. Grade 1 is the highest ANSI/BHMA duty tier, which is what an institutional or MRO spec normally calls for on equipment access and lockout points.
9) How is the BEST 1W7R4 wired in, and what should the electrician allow for?
Connections are made at screw terminals, so no soldering or special crimp tooling is needed. Kill power before starting, then mount the unit with enough clearance behind it for wiring access, ventilation and later service. Use wire gauge and connectors sized for the 15 amp application load, follow the manufacturer wiring diagram, then energize and test each of the four SPDT switches through both key positions before signing it off.
10) What finishes does the BEST 1W7R4 switch lock come in for matching existing hardware?
Nine finishes are offered: 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. Every one of them is available with or without the weather resistant box. For a facility standardized on 626 satin chrome across its lever trim and cylinders, the switch lock matches without a special order.
