Camden CM-1190-7224 Cast Aluminum Flush Mount Single Gang Key Switch Control, DPDT Maintained, Red and Green 24V LEDs

No cylinder is included. The CM-1190-7224 accepts virtually any 1 inch to 1-1/4 inch mortise cylinder and cam, both sold separately, so you can key it into whatever system already runs the building. Order the cylinder and the correct cam alongside the switch or it will not be operable on install day.

It is a single gang flush mount unit measuring 2-3/4 inches wide by 4-1/2 inches high with 1.5 inches of depth behind the plate, so you need a standard single gang box or back box with at least that 1.5 inch clearance for the switch bracket and wiring.

Maintained means the switch stays in whichever position you turn the key to and holds that state until someone keys it back. That is what you want for locking down or unlocking a door for a shift, arming a system, or holding a mag lock released. Momentary is the choice for a single release pulse to unlock a door once. The CM-1190-7224 is the DPDT maintained version, and double pole double throw gives you two independent sets of transfer contacts off one key turn, so you can switch a lock circuit and a monitoring or signal circuit at the same time.

The LEDs on this version are 24V. Plan on a 24 volt source for the indicators, or specify the 12V LED variant of the CM-1190 instead. The switch contacts themselves are dry and independent of the LED supply, so the LED voltage only governs the indicator feed.

Yes, and that is the usual reason to spec a mortise key switch. Because it takes any 1 inch to 1-1/4 inch mortise cylinder with the matching cam, your locksmith can supply a cylinder in your existing keyway and key it into the building master or a restricted maintenance key. The cylinder is a separate order item.

It is built for abuse. The faceplate is 1/4 inch thick cast aluminum, and the faceplate and switch bracket are a single piece rather than a plate screwed to a separate assembly, which is what usually gets pried on. Camden rates the line as vandal resistant and it is a commercial grade device.

None. It is a hardwired mechanical key switch with dry contacts and indicator LEDs, with no wireless communication and nothing to program. It simply switches whatever circuit you wire it into, so it works with any access control panel, mag lock, or electric strike circuit that accepts a dry contact input.

The CM-1190 bracket will take 1 or 2 contact switches, so the housing supports a second switch block if your circuit count grows. The CM-1190-7224 ships configured as DPDT maintained.
