Tactile Switch SPST-NO Top Actuated Surface Mount ## Engineering Specification ## General Description The **MSLPT5252AG2TR** is a TE Connectivity ALCOSWITCH low-profile tactile switch designed for compact electronic devices, printed circuit board assemblies, portable electronics, control panels, and user-input interface applications. It provides momentary tactile feedback when pressed and returns to its normal open state when released. The device is suitable for applications requiring a small surface-mount switch with reliable actuation, compact board footprint, and low-profile mechanical construction. ## Device Identification Manufacturer Part Number: **MSLPT5252AG2TR** Manufacturer: **TE Connectivity** Brand Series: **ALCOSWITCH** Product Family: **LPT Low-Profile Tactile Switches** Device Category: **Electromechanical Component** Device Type: **Tactile Switch** Switch Function: **Single Pole Single Throw, Normally Open** ## Functional Description The device functions as a momentary user-input switch. When the actuator is pressed, the internal contacts close and allow an electrical signal path. When the actuator is released, the switch returns to its normally open condition. This makes the component suitable for button input, menu control, reset functions, mode selection, and general human-machine interface designs. ## Mechanical Description The switch uses a compact low-profile construction with a top-actuated flush actuator. It is intended for surface-mount installation on printed circuit boards and is suitable for space-constrained designs where low height and small board area are required. ## Electrical Description The MSLPT5252AG2TR is designed for low-current DC switching applications. It should be used within the manufacturer’s specified voltage and current ratings to ensure reliable operation and long service life. The switch is intended for signal-level control applications rather than high-power load switching. ## Contact and Material Description The switch includes stainless steel contact base material with silver contact plating. This construction supports reliable contact performance for tactile input applications and helps provide stable electrical switching behavior during normal operation. ## Mounting and Assembly Description The component is supplied as a surface-mount tactile switch suitable for automated PCB assembly. Proper land pattern design, soldering profile control, and mechanical clearance should be followed according to the manufacturer’s recommended layout and assembly guidelines. ## Application Suitability The device is suitable for portable electronic devices, consumer electronics, handheld equipment, control buttons, reset switches, interface panels, communication devices, instrumentation, remote controls, and compact PCB-based user-input systems. ## Design Considerations The switch should be placed in a location that allows direct actuator access without excessive mechanical side loading. PCB layout should provide proper solder pad support and mechanical stability. The design should avoid overtravel, excessive actuation force, contamination, and use beyond the rated electrical limits. ## Hashtags #commonpartslibrary #electromechanicalcomponent #tactileswitch #pushbuttonswitch #momentaryswitch #spstswitch #normallyopen #teconnectivity #alcoswitch #mslpt5252ag2tr #lptseries #smtcomponent #surfacemount #pcbdesign #electronicscomponents #electronicparts #switchcomponent #hardwaredesign #userinterface #embeddedhardware #consumer electronics #portableelectronics #componentlibrary #engineeringparts #electronicsengineering
