Camden CM-45/10 N/O & N/C Replacement Switch
Overview
The Camden CM-45/10 is a normally-open/normally-closed (N/O & N/C) switch built as a replacement or service component for the Camden CM-40, CM-41, CM-45, and CM-60 series lock and strike products. It's rated 15A at 30VDC, making it suited to the internal switching duty these lock series call for rather than general-purpose low-voltage signaling. If you're maintaining a fleet of Camden electric strikes or locks in these series, the CM-45/10 (often searched as CM 45/10) is the part number to specify when a field unit's internal switch needs replacing rather than swapping the whole lock body.
Key Features
- N/O & N/C switching: a single component gives you both a normally-open and normally-closed contact, so it can drive status monitoring or interlock logic on the host lock without adding a second switch or relay.
- 15A @ 30VDC rating: headroom well above typical low-voltage access control signaling loads, so the switch contact itself won't be the weak point in the circuit under repeated cycling.
- Direct fit for CM-40, 41, 45, and 60 series: stocking this one part number covers service and repair across four Camden lock/strike families instead of sourcing a different switch per model.
Integration & Compatibility
The CM-45/10 is a service/replacement part, not a standalone lock — it installs into existing CM-40, CM-41, CM-45, or CM-60 series hardware. Confirm the specific lock model and its internal switch mounting before ordering, since fit is tied to that host hardware rather than to a generic footprint. This SKU is listed as end-of-life; confirm current stock before specifying it for new installs, and consider it primarily for maintaining lock/strike hardware already in the field.
Frequently Asked Questions
Q: What lock series is the Camden CM-45/10 compatible with?
A: The CM-45/10 is built for the Camden CM-40, CM-41, CM-45, and CM-60 series locks and strikes as a replacement N/O & N/C switch component.
Q: What is the voltage and current rating of the CM-45/10?
A: The switch is rated 15A at 30VDC.
Q: Does the CM-45/10 provide both normally-open and normally-closed contacts?
A: Yes, it is an N/O & N/C switch, providing both contact types from a single component.
Q: Is the Camden CM-45/10 still in production?
A: This part is listed as end-of-life. Confirm current stock availability before specifying it for a new installation.
Q: Is there a warranty on the CM-45/10?
A: It carries a manufacturer warranty; contact for specific duration terms as this SKU is end-of-life.
The CM-45/10 is a narrow-purpose part: an N/O & N/C switch rated 15A at 30VDC, built to service Camden's CM-40, CM-41, CM-45, and CM-60 lock and strike series. I get calls on this one specifically when a tech has an otherwise-working lock body with a dead internal switch and doesn't want to replace the whole unit.
Technical Highlights:
- 15A @ 30VDC rating: comfortably above the switching loads these lock series see, so the contact isn't the failure point under normal cycling.
- N/O & N/C in one part: covers both status-monitoring and interlock wiring configurations without stocking two separate switches.
- Cross-series fit (CM-40/41/45/60): one stocked part number services four lock families, which simplifies spares inventory for a facilities or integration team.
Deployment Considerations:
- This is a service/replacement component, not a standalone lock — verify the exact host lock model before ordering, since fit depends on the specific CM series unit it's going into.
- This SKU is listed end-of-life. If you're speccing new installs rather than repairing fielded hardware, confirm stock and get replacement guidance before committing a design to it.
Best fit: a facilities or integration team maintaining existing Camden CM-40/41/45/60 series locks in the field who needs a drop-in switch replacement rather than a full lock swap — not a spec for new-build designs given its end-of-life status.
