1. An LED tube lamp, comprising:

  • a glass tube;

    two end caps disposed at two ends of the glass tube, at least one of the end caps having a main body, an actuator configured to move toward and extend away from the glass tube, a micro switch and an electrically conductive pin, wherein the actuator includes a flange extending radially at an intermediary portion of the actuator and wherein the micro switch is configured to be triggered by the actuator being pressed when the electrically conductive pin receives an external driving signal;

    a power supply module, disposed in at least one end cap and coupled to the electrically conductive pins of the two end caps; and

    an LED light strip disposed inside the glass tube with at least one LED light source that is mounted on the LED light strip and electrically connected with the power supply module through the LED light strip;

    wherein, the glass tube includes a diffusion film to allow the light emitted from the least one light source of the LED tube lamp to pass through the diffusion film and the glass tube surface in sequence; and

    the micro switch when triggered completes a circuit between the electrically conductive pin and the power supply module.
