It provides a secure, key-actuated means of opening a control circuit, making it suitable for access control, security, and building automation systems. Licensed electricians and security integrators typically specify this type of switch where a physical key is required to interrupt or initiate a low-voltage control signal. The N\/C configuration means the circuit is complete at rest and opens when the key is turned.\u003c\/p\u003e\u003cp\u003eThis key switch is used in commercial and light industrial access control installations, security panel applications, and building entry systems where tamper-resistant manual circuit control is required. It is appropriate for door release circuits, alarm bypass functions, and similar low-voltage switching tasks where a keyed override or authorization step is part of the system design. Surface or panel mounting makes it adaptable to a range of enclosure types and field conditions.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eNormally closed (N\/C) contact configuration opens circuit on key actuation\u003c\/li\u003e\n\u003cli\u003eSingle-pole single-throw (SPST) switching for straightforward circuit control\u003c\/li\u003e\n\u003cli\u003eKey-operated actuation provides physical access authorization\u003c\/li\u003e\n\u003cli\u003eDesigned for surface or panel mount installation\u003c\/li\u003e\n\u003cli\u003eSold individually as a single unit\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct installation component for low-voltage access control and security systems requiring a key-operated N\/C SPST switch.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is typically performed by a licensed electrician or qualified security systems integrator. De-energize the control circuit completely before wiring or replacing the switch. Follow applicable NEC requirements for low-voltage control wiring in the jurisdiction of installation. Do not exceed the rated electrical limits of the switch when connecting to control panels or alarm circuits.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eContact Configuration\u003c\/strong\u003e: Normally Closed (N\/C)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSwitch Type\u003c\/strong\u003e: Single-Pole Single-Throw (SPST)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting Style\u003c\/strong\u003e: Panel or surface mount\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: Each (1 per unit)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: Alarm Controls Corporation\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: KA-107ANC\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ALARM CONTROLS","offers":[{"title":"Default Title","offer_id":51561532326194,"sku":"KA-107ANC","price":241.37,"currency_code":"USD","in_stock":true}],"url":"https:\/\/voomisupply.com\/products\/alarm-controls-corporation-ka-107anc-key-switch-nc-spst","provider":"Voomi Supply","version":"1.0","type":"link"}
