<p>Device has a hand operated element that moves a pressure pin along to move a holder, an electric switch acting on the catch via a control arrangement and a sensing element spring-loaded in its deployed position and moved by the pressure pin. The radially elastic holder is pressed with friction against peripheral profiling on the pressure pin, which can be moved into the holder by a control force greater than the frictional force. The device has a hand operated element (10) that moves a pressure pin (30) along when manually operated to move a holder (37), an electric switch (25) acting on the catch via an electronic and/or mechanical control arrangement and a sensing element (20) spring-loaded in its deployed position and moved by the pressure pin. The radially elastic holder is pressed with friction against peripheral profiling (38) on the pressure pin, which can be moved axially into the holder by an axial control force greater than the frictional force.</p> |
