Can you please help me identify these components and state their function? These were taken from the inside of a digital thermometer.

    \$\begingroup\$ @Trevor That little thing to the left is one of those silicone rubber buttons, I think. \$\endgroup\$ – jonk Sep 22 '17 at 16:40
  • \$\begingroup\$ @jonk ya you are probably right. Fuzzy picture though. \$\endgroup\$ – Trevor_G Sep 22 '17 at 16:43

    \$\begingroup\$ @Trevor Translucent silicon rubber buttons are inherently fuzzy-looking. ;) \$\endgroup\$ – jonk Sep 22 '17 at 16:47
  • \$\begingroup\$ no chance of getting it work again but all it needed was a new coin cell that is bulged but the bottom piezo disc is still intact. \$\endgroup\$ – Tony Stewart Sunnyskyguy EE75 Sep 22 '17 at 17:27

It looks like the baby got your digital thermometer.

  • LCD (liquid crystal display) provides a human readable display of the temperature in adequate light.
  • Metallic contacts provide connections - most likely from the circuit board to the battery (see below).
  • Screw(s) skruː noun, a short, slender, metal pin with a raised helical thread running around it and a slotted head, used to join things together by being rotated so that it pierces wood or other material and is held tightly in place.
  • Probably the push-button membrane which is designed to bridge out contacts on the PCB to turn on and off the thermometer.
  • A 'coin' cell to power the electronics.
  • A piezo buzzer used to generate an audible 'beep' when a stable measurement has been obtained.
  • The battery cap.

Check the baby's diaper / nappy for the rest of the parts including the sensor and PCB.

  • \$\begingroup\$ Hahaha, I am thinking what if she really find a PCB in the diaper. \$\endgroup\$ – Hazem Sep 22 '17 at 18:38
  • \$\begingroup\$ Don't forget to accept the answer if it is correct, thanks. \$\endgroup\$ – Transistor Sep 23 '17 at 14:12
