It is designed for access control and door release applications, providing a clean, durable switching point at entry and egress locations. The momentary action means the circuit activates only while the button is held, making it well suited for electric strike and magnetic lock release circuits. Licensed electricians and low-voltage access control technicians are the primary installers of this device.\u003c\/p\u003e\u003cp\u003eThe MCK-4 is used in commercial and light industrial access control systems, typically mounted at doors, gates, or secured entry points where a wall-mounted momentary switch is needed to release an electric locking device. It fits standard single-gang electrical boxes and is appropriate for new construction and retrofit installations alike. Its stainless steel finish suits high-traffic environments where durability and appearance both matter.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSingle-gang stainless steel plate for durable, corrosion-resistant surface mounting\u003c\/li\u003e\n\u003cli\u003eOne SPDT momentary push button rated at 4 amps for compatibility with common door release circuits\u003c\/li\u003e\n\u003cli\u003eMomentary action provides momentary circuit closure, preventing unintended sustained activation\u003c\/li\u003e\n\u003cli\u003eSPDT switching allows normally open or normally closed wiring configurations\u003c\/li\u003e\n\u003cli\u003eCompact single-gang form factor fits standard electrical boxes\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or new-installation component for single-gang access control button applications using SPDT momentary switching in electric strike, magnetic lock, or door release control circuits.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed electrician or qualified low-voltage access control technician in accordance with applicable NEC requirements. De-energize the access control panel and any connected door hardware before wiring. Confirm the load current of the connected locking device does not exceed the 4-amp switch rating. Secure the plate firmly to a standard single-gang electrical box before restoring power.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSwitch Type\u003c\/strong\u003e: SPDT Momentary\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCurrent Rating\u003c\/strong\u003e: 4 amps\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePlate Material\u003c\/strong\u003e: Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGang Size\u003c\/strong\u003e: Single Gang\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eQuantity per Unit\u003c\/strong\u003e: 1\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: MCK-4\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ALARM CONTROLS","offers":[{"title":"Default Title","offer_id":51687532364082,"sku":"MCK-4","price":254.8,"currency_code":"USD","in_stock":true}],"url":"https:\/\/voomisupply.com\/products\/alarm-controls-corporation-mck-4-spdt-momentary-push-button-plate","provider":"Voomi Supply","version":"1.0","type":"link"}
