BEST 1W7K4626 – Frequently Asked Questions

1) What is the BEST 1W7K4 electric switch lock actually used for?
It's a key-operated electrical switch, not a door lock. The 1W7K4 puts a DPDT (double pole, double throw) toggle switch behind a BEST keyed cylinder, so only a keyholder can throw the circuit. Typical uses are control panel security, equipment access control, facility power management, and emergency system override. Buy it when you need a switch someone can't operate without a key, not when you need to secure an opening.
2) Can the BEST 1W7K4 switch lock be keyed into our existing BEST master key system?
Yes. The 1W7K4 uses a BEST interchangeable core, so it drops into any BEST keying system and can sit on the same master key as the doors in the building. That also means it rekeys with a control key like the rest of your cores, no disassembly of the switch. Facilities standardizing on BEST SFIC get one key for the openings and the control switches both.
3) What voltage and amperage can the BEST 1W7K4 key switch handle?
Contact rating is 110 VAC at 15 amps resistive, or 220 VAC at 10 amps resistive, with 1/2 HP at 250 VAC for motor loads. Those are resistive figures, so an inductive load (motor, contactor coil, ballast) is governed by the 1/2 HP number rather than the 15 amp one. If your load exceeds that, switch a relay or contactor coil with the 1W7K4 instead of running the load through it directly.
4) What do the 2 o'clock and 10 o'clock key positions on the BEST 1W7K4 mean?
The key rotates to two working positions, Key Position 2 at 2 o'clock and Key Position 3 at 10 o'clock, and the action is maintained, so the switch stays where you leave it after the key is turned. With DPDT contacts, that gives you two independent circuits transferred between two states, for example one circuit enabling equipment while the second signals a panel or annunciator that it's been enabled.
5) Do I need to order the SWR weather resistant box with the BEST 1W7K4, or can I mount it in my own enclosure?
Box Option is a choice you make on the order. Pick SWR (Standard Weather Resistant) if the switch sits outdoors, in a wash-down area, or anywhere damp, and pick None if you're mounting the unit into an existing control panel or enclosure that already provides the protection. Both box options are offered in all eight finishes. Note that a bare unit needs its own mounting hole and clearance behind for the wiring, so decide this before the panel is cut.
6) How hot can the environment get where a BEST 1W7K4 key switch is installed?
Rated for operation up to +221 F (+105 C), which covers mechanical rooms, boiler rooms, and equipment enclosures that sit well above ambient. That's the spec to check first if the switch is going on a panel door where internal heat builds up.
7) Is the BEST 1W7K4 switch lock heavy duty enough for an industrial plant?
Grade 1, heavy duty, and specified as commercial rather than residential. The cylinder uses a double D design that keeps it from slipping or turning in the housing under repeated hard key operation, which is the usual failure point on cheaper key switches in a plant setting.
8) How does the BEST 1W7K4 wire in, and what does the electrician need to bring?
Screw terminals, so it lands standard field wiring with no crimped harness or connector kit. Size the conductors to the load you're switching, not to the switch's maximum. Because it's DPDT you're landing more conductors than a simple on/off key switch, so allow the depth behind the mounting surface for that. Power gets killed before the unit goes in, and the manufacturer's wiring diagram governs which pole is which.
9) Will the BEST 1W7K4 replace a standard toggle switch in my panel?
Functionally it's a DPDT maintained toggle, so it does the same electrical job as an ordinary DPDT toggle switch within the 110 VAC / 15 amp resistive rating, with the difference that operation requires a BEST key. Mechanically it is not a drop-in for a standard toggle bushing hole; a key cylinder body needs its own prep. Plan the panel cutout around the 1W7K4, or order it with the SWR box and mount it as a standalone unit.
