BEST 1W7A1626 – Frequently Asked Questions

1) What is a BEST 1W7A1 electric switch lock actually used for?
It's a key-operated electrical switch, not a door lock. Turning the key throws an SPDT (single pole, double throw) contact with maintained action, so the circuit stays in the position you leave the key in. That's how you get keyed control over a circuit: control panel power, machine and equipment switching, emergency system controls, and access control on electrical equipment. If you're looking for something to latch a door, this is the wrong part.
2) Can the BEST 1W7A1 switch lock be keyed into our existing BEST master key system?
Yes. The 1W7A1 takes a BEST interchangeable core and may be keyed into any BEST system, so it drops into an existing master key hierarchy alongside the rest of your BEST cylinders. For a facility standardized on BEST SFIC, that means the same key ring that opens the doors can also throw this switch, with no separate key to track.
3) Will the 1W7A1 handle 120V line voltage, or is it low voltage only?
It covers both. The switch is rated from 28 VDC up to 250 VAC, with contact ratings of 28 VDC at 10 amps resistive and 125/250 VAC at 10.1 amps resistive. So a 120V branch circuit is within range, and so is a 24V control loop. Size your load against the resistive rating, and note the separate horsepower rating below if you're switching a motor.
4) Can I use a keyed switch lock to start and stop a motor directly?
For motor loads the number that matters is the horsepower rating, not the resistive amp rating. The 1W7A1 carries a 125 VAC, 1/4 HP rating, so it will directly switch a fractional horsepower motor at 125 VAC. Anything larger than 1/4 HP should be switched through a contactor or starter with the switch lock in the control circuit, which is the usual way these get wired into a control panel anyway.
5) Do I need to order a box with the BEST 1W7A1, and which one?
The box is an option you specify with the order, and there are five choices: None if you're mounting into an enclosure or panel cutout you already have, INT for an interior box, OC1 for a standard octagon, OC2 for a deep octagon when you need extra room behind for wiring, and SWR for a standard weather resistant box on an exterior or wash-down location. Pick the box at the same time as the finish, since both are part of how the unit is ordered.
6) Can a BEST 1W7A1 switch lock be mounted outdoors or in an unheated space?
Environmentally, yes on both counts. The unit is rated for operation from -85 degrees F to +257 degrees F (-65 to +125 C), which covers unheated mechanical rooms, rooftop equipment, and cold storage. For an exposed location, order it with the SWR standard weather resistant box rather than a plain octagon.
7) What finishes does the BEST 1W7A1 come in to match the rest of our hardware?
Nine standard BHMA 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. If your building is standardized on 626 satin chrome or 613 oil-rubbed bronze like most commercial and hospitality work, the switch plate will read as part of the same hardware set rather than an add-on.
8) Will the key stay turned, or does it spring back when I let go?
Maintained action, so the contacts hold the position you turn the key to and stay there when you release. That's what you want for an on/off disconnect, a lockout, or a bypass you need to leave engaged. If your application needs the circuit to be live only while the key is held (a momentary or spring-return function), the maintained SPDT is the wrong configuration for it.
9) Is the BEST 1W7A1 heavy duty enough for an industrial control panel?
It's built as a Grade 1 heavy duty commercial unit, and all switches in the range are UL recognized or listed. The cylinder uses a Double D design that stops the cylinder slipping or turning in its mounting under repeated key torque, which is the usual failure point on keyed switches in high-cycle industrial use.
10) What does SPDT give me that a simple on/off keyswitch does not?
A single pole, double throw contact has a common and two outputs, so one key position energizes one circuit and the other position energizes a second. That lets one key transfer between two states rather than just breaking power: normal versus bypass, primary versus backup, or an interlock that signals a panel which mode it's in. If all you need is to break one circuit, you're paying for a throw you won't wire.
11) What do I have to check before wiring in a BEST keyed switch lock?
Confirm your supply voltage and current draw fall inside 28 VDC to 250 VAC and within the 10 amp resistive contact rating before anything else, since the load decides whether this switch is the right one. Kill power at the source before you start, mount with enough clearance behind for wiring access and later service (that's what the OC2 deep octagon box is for), and land the conductors per the BEST wiring diagram for the SPDT configuration.
