Pass & Seymour 500-K – Frequently Asked Questions

1) What is the Pass & Seymour 500K switch key used for?
The 500K is a momentary contact switch key, meant to actuate Pass & Seymour heavy duty locking switches. It is the removable key an electrician or facility tech uses to operate a switch that stays locked out to anyone without one, which is why it shows up on secured equipment control panels and in commercial and industrial installations.
2) Will the Pass & Seymour 500K key work with any brand of locking switch?
It's built for Pass & Seymour heavy duty locking switches. Other manufacturers' locking switches use their own key profiles, so don't assume a cross-brand fit. If the locking switch in the panel is a Pass & Seymour heavy duty unit, the 500K is the matching key; if it is another brand, match the key to that brand's switch.
3) Can I order spare 500K keys to standardize across a building's locking switches?
Yes. The 500K is sold as a standalone key under Pass & Seymour part number 500-K, so facilities running multiple heavy duty locking switches can stock spares for maintenance staff rather than pulling a key off one panel to work another. It is a replacement/spare part, not a switch, so order the switch separately if you also need the device.
4) Does the Pass & Seymour 500K key come with the switch, or is it a separate part?
Ordering a 500K gets you the key by itself. It does not include a locking switch, wallplate, or mounting hardware. Buyers replacing a lost key only need this; buyers building a new secured control point need the heavy duty locking switch as well.
5) What does momentary contact mean on a locking switch key like the 500K?
Momentary means the circuit is made only while the key is turned and held, and it returns as soon as you release. That suits start/stop or jog control on secured equipment rather than leaving a load energized. If you need the switch to stay in position after the key is turned, a momentary contact device is the wrong function.
6) Where is the Pass & Seymour 500K made?
Mexico. Pass & Seymour is a Legrand brand, and the 500-K is listed with Mexico as country of origin, which is the detail government and institutional buyers usually need for procurement paperwork.
