Abstract
A probe head includes a stationary component and pressure-sensitive sensors, the sensors being stationary relative to the fixed component, and a deflectable probe element. The probe element has a longitudinal axis, a first contact point and a second contact point. Because of contact of the probe element, pressure forces are able to be introduced into the sensors via the first contact point. In response to a further deflection of the probe element, the latter is able to be transferred to a stop position, in which the second contact point of the probe element touches the stationary component in a supporting manner. The probe element is arranged such that the pressure forces that are able to be introduced into the sensors in the stop position are limited, a first distance between the first contact point and the longitudinal axis being shorter than a second distance between the second contact point and the longitudinal axis.
