A communication console may include a moveable plunger including a body and an arm. The arm may connect to and extend away from the body. A first element may be coupled to the arm. The first element may include a top point and a bottom point, the axis of displacement extending between the top point and the bottom point. The first element may move with the arm along the axis of displacement. A second element may be detached from the arm and positioned adjacent to the axis of displacement. Additionally, one of the first element or the second element may be a sensing element and another may be a detectable element. The sensing element may sense a spatial position of the detectable element and output an indication of a position of the plunger based on the spatial position of the detectable element.

Provided is an instantaneous-interruption prevention device and a telephone that can more effectively prevent instantaneous interruption of a call due to an impact. The instantaneous-interruption prevention device includes a latch part that operates so as to come into contact with a hook button of a telephone when receiving an impact, and the latch part stops motion of the hook button by coming into contact with the hook button.

An analog-to-digital converter includes a sample hold circuit configured to receive an analog input signal based on an operating mode, the operating mode being one of at least two modes including a sample mode and a hold mode. The sample hold circuit includes a first transistor including a control terminal and a first terminal, the first transistor configured to receive a control signal via the control terminal and receive the analog input signal via the first terminal. The analog-to-digital converter further includes a bootstrap switch operationally connected to the control terminal and the first terminal of the first transistor, the bootstrap switch configured to form a first current path from a power source based on the analog input signal and a boosted voltage of the control terminal of the first transistor in the sample mode, the control terminal bing along the first current path in the sample mode.
