Sized at 3\/8 inch in diameter, it mounts directly into a drilled hole using a D-clip retention method, eliminating the need for additional hardware. The TSC-20 provides a tamper-detection function at door or window frames, triggering an alert when a protected enclosure or door is opened or disturbed. Security system installers and low-voltage technicians are the primary trades who specify and install this contact type.\u003c\/p\u003e\n\u003cp\u003eThe TSC-20 is suited for residential and light commercial security installations where recessed, concealed door contacts are required. Its adjustable design allows for field tuning of the actuator gap, making it adaptable to varying door frame thicknesses and closure tolerances. Typical applications include entry doors, equipment enclosure panels, and access points in intrusion detection systems where a flush, low-profile contact is preferred over surface-mount alternatives.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3\/8 inch diameter body fits standard recessed contact bore\u003c\/li\u003e\n  \u003cli\u003eD-clip mounting method for tool-assisted press-fit installation without screws\u003c\/li\u003e\n  \u003cli\u003eAdjustable actuator for field-tunable gap tolerance\u003c\/li\u003e\n  \u003cli\u003eTamper-detection functionality suitable for intrusion alarm systems\u003c\/li\u003e\n  \u003cli\u003eRecessed profile keeps contact concealed and tamper-resistant from the exterior\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style recessed contact for standard 3\/8 inch bored door and frame installations in residential and commercial intrusion detection systems.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by a licensed low-voltage or alarm systems technician. Deactivate and disarm the security panel before wiring or replacing any contact. The D-clip body should be pressed into a clean, properly sized bore hole to ensure secure retention and consistent actuation. Follow local low-voltage wiring codes and the panel manufacturer's wiring guidelines when connecting to the alarm control board.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMounting Type\u003c\/strong\u003e: D-Clip recessed\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Diameter\u003c\/strong\u003e: 3\/8 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAdjustable Actuator\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCategory\u003c\/strong\u003e: Recessed Contacts\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: Each\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eQuantity Per Package\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: George Risk Industries Inc.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: TSC-20\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GEORGE RISK INDUSTRIES INC.","offers":[{"title":"Default Title","offer_id":51687826358578,"sku":"TSC-20","price":29.91,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7ed1a2ea1ed2cf3a5e83fa995d743e38.jpg?v=1788237439","url":"https:\/\/voomisupply.com\/products\/george-risk-industries-tsc-20-recessed-tamper-switch","provider":"Voomi Supply","version":"1.0","type":"link"}
