Introduction to the CDVI KEY-SSMAKD
CDVI KEY-SSMAKDis a surface-mount stainless-steel 2-position maintained key switch designed for straightforward, reliable access-control and equipment-isolation tasks. Supplied with two keys keyed to differ, the unit provides double-pole switching (2 x NO/NC) and is rated at 2 A @ 24 Vdc. Its stainless-steel faceplate and robust mechanical life make it suitable for commercial and industrial environments where durability, simplicity and physical security matter.

Detailed specifications and benefits
Understanding the technical details helps clarify where this key switch excels and what limitations to expect. Below are the main specifications and the practical benefits they deliver.
- Manufacturer / model:CDVI KEY-SSMAKD (Ref E0901D000091)
- Function:2-position, maintained, keyed to differ
- Contacts:2 x NO/NC (double-pole)
- Contact rating:2 A @ 24 Vdc
- Mounting:Surface mount, square plate
- Material / finish:Stainless steel plate (silver)
- Mechanical life:Tested to ≈500,000 operations
- Operating temperature:−20 °C to +55 °C
- Dimensions:85 mm × 85 mm × 30 mm (H × W × D)
- Weight:≈0.350 kg
- Supplied keys:2 keys (keyed to differ)
- Warranty:2 years (reseller listings — confirm with manufacturer)
- Datasheet:Official CDVI datasheet & installation manual available (links provided by supplier)
- Double-pole switching:The 2 x NO/NC contacts allow you to isolate two separate circuits simultaneously (for example supply and control) or wire complementary fail-safe logic. This increases installation flexibility and safety compared with single-pole key switches.
- Maintained (latching) action:The 2-position maintained operation gives a clear on/off state that remains until the key is turned again — ideal for enabling equipment, locking a control state or toggling access modes.
- Stainless-steel surface plate:Robust against everyday wear, corrosion and vandalism; the surface-mount design simplifies retrofits where in-wall installation is impractical.
- Commercial reliability:Cycle testing to ~500,000 operations indicates long life in medium- to high-use locations such as apartment building access points, commercial gates and shared facilities.
- Compact footprint:The 85×85 mm square plate is a standard, unobtrusive size that integrates well into architectural surrounds.
Use cases and scenarios where the product excels
The CDVI KEY-SSMAKD is built for simple, secure control tasks. Typical deployments include:
- Gate and roller-shutter control:Provide key-authorised control to open/close gates or shutters without the need for electrical re-wiring of existing actuators. Double-pole contacts let you interrupt both control and power lines if required.
- Equipment enable/disable:Use as a secure on/off for machinery, site power to specific circuits or as a maintenance isolation switch where authorised staff require a physical key to re-enable equipment.
- Plant room access and control panels:Robust stainless finish and ease of mounting make it suitable for plant rooms, service cupboards and control cabinets where vandal-resistance and simple operation matter.
- Secondary access control points:Use in conjunction with electronic access control (e.g. card readers) as a mechanical override or for low-cost secondary control points where full reader hardware is unnecessary.
- Retail or hospitality environments:For back-of-house door access, till lockouts, or secure overrides where staff need a physical key to enable systems.
Comparisons with similar products in the market
When choosing a key switch you will typically consider mechanical key switches, flush-mount units, electronic keypads or proximity readers. Here is how the CDVI KEY-SSMAKD compares to common alternatives.
Flush-mount units sit inside a panel or wall and can provide a cleaner look. The CDVI surface-mount model wins on simplicity and retrofit speed — no cutting of walls or complex mounting — and the stainless faceplate still gives a high-end finish. If you need a fully recessed, tamper-proof installation, consider a flush-mount alternative; if you prefer fast installation and robust aesthetics, the surface-mount CDVI model is ideal.
Many low-cost key switches use plastic faceplates or lower-grade metals. The stainless-steel plate of the CDVI unit provides better durability, corrosion resistance and appearance. The verified mechanical life (≈500,000 cycles) also tends to outperform cheaper alternatives, which may fail earlier in higher-use locations.
Electronic keypads and readers provide more flexible credentialing and audit trails, but at higher cost and complexity. The CDVI key switch is a low-tech, low-maintenance solution that does not require network integration, power beyond the switched circuit, or ongoing credential management. Use the CDVI when you need simple, reliable mechanical control rather than full access management features.
- If you need centralized logging, user management or remote provisioning, choose an electronic access control solution.
- If high current switching above 2 A @ 24 Vdc is required, use a properly rated contactor or relay controlled by the key switch instead of direct switching.
- If recessed installation or flush aesthetics are mandatory, select a flush-mount variant.

Pricing, warranty and next steps
Current supplier details indicate a cost_price of 56.51 (currency unspecified) and a preliminary suggested_price of 67.27. The suggested_price shown is a tax-exclusive recommended retail price (RRP) computed to meet a minimum 16% gross margin (calculation: cost_price / 0.84 = suggested_price). Please confirm the following so we can provide rounded RRPs and VAT-inclusive values:
- Is the cost_price 56.51 in GBP, USD, EUR or another currency?
- Should the final RRP include VAT/sales tax (for example UK VAT at 20%) or be shown tax-exclusive?
Warranty is typically listed as 2 years for reseller listings; confirm with the manufacturer if extended warranty or country-specific terms are required. The official CDVI datasheet and installation manual should be consulted for detailed wiring, mounting and safety guidance.
Conclusion: why choose the CDVI KEY-SSMAKD
TheCDVI KEY-SSMAKDis a pragmatic choice for organisations that need a robust, low-complexity mechanical switching solution. Its stainless-steel surface plate, maintained two-position action, double-pole contacts and long mechanical life make it particularly well-suited to gates, roller shutters, equipment isolation and secondary access points where appearance and durability matter. It occupies a sweet spot between cheap, low-quality switches and complex electronic access systems — offering dependable physical control, quick installation and clear on/off states without the overhead of a managed access platform.
