Emergency call buttons that work when it matters most.
An emergency call point that fails when needed is worse than no call point at all. These products sit idle for months or years in extreme conditions, then must activate correctly on the first press. No second chances. RNC solid-state interfaces eliminate the mechanical failure modes that make conventional emergency buttons a liability.
Emergency call button, panic button, help point: one solid-state platform.
An emergency call button is pressed rarely, sometimes never, and it has to work the one time it matters. RNC Technologies emergency push buttons are solid-state piezo switches with no moving parts: nothing to jam, corrode or wear out while the button waits. The same platform serves as a panic button behind a counter, a help point on a station platform or in a car park, a call button inside an elevator, or a nurse call button at a bedside. Every application uses the same sealed switch, sized and configured for the location.
Each unit is sealed to IP69K and rated IK10, so it survives weather, washdown cleaning and deliberate abuse without losing sensitivity. It reports its own status so an operator knows it is working, rather than discovering a fault only when someone presses it in an emergency. Illumination, tactile guidance and integration with intercom, SIP and PoE call systems are configured per project, alongside the same RNC piezo switches used across the rest of the site.
Where failure is not an option.
Why solid-state piezo for emergency equipment.
The defining characteristic of this market is that failure is not measured in inconvenience or cost, but in safety. A call point that does not respond when pressed is a liability. Every design decision must serve one objective: the button works when someone needs it.

If an emergency call point fails silently, the failure is only discovered when someone needs it most. PT Plus self-diagnostic capability changes this.
Every station in the network can be remotely verified without physical activation. Basic self-diagnostic confirms electronics health. Full self-diagnostic tests the complete signal chain including the mechanical interface. For safety-critical applications, this is not a convenience feature. It is the difference between a network you know works and a network you hope works.
Proven in the most demanding conditions.
RNC piezo switches are deployed in emergency communication stations manufactured by leading North American and European OEMs, operating across campus, parking structure, public space, and transit environments.
A European transit authority replaced mechanical call points across a network of remote solar-powered platform stations operating in conditions reaching -40C. Previous buttons required annual replacement due to seal degradation and contact corrosion. RNC switches have operated continuously with zero maintenance interventions. Power draw is below the battery's self-discharge rate.
