BEST 1W7B3626 – Frequently Asked Questions

1) What is the BEST 1W7B3 switch lock actually used for?
It's a key-operated electrical switch, not a door lock. The 1W7B3 carries a single SPDT (single pole, double throw) switch with maintained action, so the key turns the circuit on and it stays there until you turn it back. Typical placements are control panels, machine controls, lockout/tagout points, building automation and override controls, where you want only a keyholder able to change the state of a circuit.
2) Can the 1W7B3 switch lock handle a 15 amp 125 VAC circuit or a fractional horsepower motor?
Contact rating is up to 15 amps at 125 VAC resistive, and 1/2 HP at 125 to 250 VAC for motor loads. That covers a fractional-horsepower motor start/stop at either voltage and a resistive load up to 15 A. Size the load against those two ratings before wiring; anything heavier should be switched through a contactor with the 1W7B3 driving the coil.
3) Will the 1W7B3 electric switch lock work with our existing BEST keying system?
It takes BEST interchangeable core technology and works with any BEST keying system, so it can be pinned into an existing master key hierarchy alongside the door locks in the building. For a facility already standardized on BEST small format cores, that means the same key that opens the mechanical room can be the key that authorizes the panel switch.
4) Do I need to order an enclosure box with the BEST 1W7B3 switch lock?
That's the choice on the Box Option axis. You can order the 1W7B3 with no box, for mounting straight into an existing panel cutout or enclosure, or with OC1, the standard octagon box, when there's no host enclosure to mount into. Every finish is offered both ways, so pick the box option by the mounting situation and the finish by the surrounding hardware.
5) Is a 1W7B3 switch lock the right part to secure a door?
No. It's a key-operated electrical switch that controls a circuit, and it has no latch or bolt, so it secures nothing mechanically. If the goal is keyed control of a door, you want a bored lockset or an electric strike released by an access control circuit, and a switch lock like the 1W7B3 is what you'd add on the wall to override or release that circuit by key.
6) What do the 2 o'clock and 12 o'clock key positions on the 1W7B3 mean?
Those are the two detented key positions of the single switch. Position 2 sits at 2 o'clock and position 3 at 12 o'clock, and because the action is maintained, the key stays put in whichever position you leave it rather than springing back. That gives a visible, mechanical indication of circuit state at the panel face, which is what makes it useful as an override or lockout control.
7) What finishes does the BEST 1W7B3 come in, and can I match the other hardware in the building?
Eight finishes: 605 bright brass, 606 satin brass, 611 bright bronze, 612 satin bronze, 613 satin bronze oil-rubbed, 619 satin nickel, 625 bright chrome, and 626 satin chrome, plus 690 statuary dark bronze. Those are standard BHMA finish numbers, so a facility already specified in 626 or 613 can carry the same number across to the switch lock. Each finish is available with or without the OC1 octagon box.
8) Will a BEST 1W7B3 switch lock hold up in a hot machine room or near process equipment?
Rated for operation up to +176 degrees F (+80 degrees C), and built as a Grade 1 heavy duty commercial unit. That temperature ceiling is the number to check against your enclosure's internal temperature, not the room ambient, since a sealed panel with drives or transformers in it runs well above the room.
9) How does the 1W7B3 wire in, and does the cylinder resist someone forcing the switch with pliers?
Connections are screw terminals, so it lands standard panel wire without special connectors or a harness. The cylinder is a double D design, which keeps the core from slipping and turning under torque, so the key position drives the switch positively instead of spinning free. Kill power at the panel before landing conductors.
10) What does SPDT get me that a simple on/off key switch does not?
A single pole double throw switch gives you a common contact plus two throws, so one key position feeds circuit A and the other feeds circuit B. That lets one key both kill a function and enable an alternate, for instance dropping automatic control and picking up a manual override, rather than just breaking a single circuit. With maintained action the selection holds without the key present in a spring-return sense.
