B-Line M22S-WRS3-MS6-A1 M22 Modular Three Position Key-Operated Selector Switch

No contact blocks are included. The M22S-WRS3-MS6-A1 ships with one key and one contact block mounting adapter, so you add the normally open or normally closed contact blocks your circuit needs on top of the switch itself. Budget for those on the same order or the device goes in dead.

It mounts in the standard 22.5 mm round panel cutout used across the M22 modular line, so it drops into an existing 22 mm hole on an enclosure door or control station.

As supplied, the key is removable in the center position only, and the switch action is maintained, so it stays where you turn it. Removal positions can be changed in the field with coding adapters if you need the key trapped in, say, the left or right position instead.

Yes. The MS6 key code is what determines that, so ordering multiple M22S-WRS3-MS6-A1 units gives you a set that all operate from the same key. Useful when maintenance staff need one key for every bypass or lockout selector on the floor.

Pick the key version when only authorized staff should change the state, auto/off/hand, bypass, or a safety override. The M22S-WRS3-MS6-A1 is key operated and maintained across three positions, so it stays put and cannot be moved without the key. If any operator is meant to switch it freely, a knob or lever selector costs you less and cycles better.

The operator itself measures 1.17 in length by 1.17 in width by .81 in height and weighs .995 lb. Depth behind the panel grows once contact blocks are stacked on the mounting adapter, so allow for those when the enclosure door is shallow.

100,000 operations. That suits shift-change and maintenance-bypass duty rather than a switch someone turns every few minutes on a production cycle; for high-frequency selection a standard knob selector is the better choice and this one is meant to restrict who operates it.

No. It is a non-illuminated operator with a black bezel, so there is no lamp block position behind it and no visual indication of state other than key position. If you need an indicated state, run a separate pilot light in an adjacent 22.5 mm hole.
