A measuring system that relate to the measurement of relatively small one degree of freedom mechanisms, such as pivoting and rotary switches, is disclosed. In particular end effectors and a kit for assembling various end effector assemblies is disclosed, that allow for accurate measurement of torque versus angular displacement curves for various types of pivoting and rotary switches.

The present invention discloses a short circuit and detection dual-purpose device used for relay protection. The short circuit and detection dual-purpose device is characterized by comprising a cuboid operation box, wherein the operation box is equipped with a buckle-type opening-closing door, and a fuse placement fastening groove is arranged in the door; the operation box is additionally equipped with a circuit on-off selection switch, a circuit on-off indication lamp, a rotary switch, a voltage display meter, a first current display meter and a second current display meter, a wiring port is arranged on the side surface of the operation box, and a short circuit alarm circuit and a detection circuit are arranged inside the operation box. Compared with the prior art, the advantages of the present invention are that: the short circuit and detection dual-purpose device is simple and reliable in circuit design, the personal low-voltage electric shock caused by that the operation personnel touch a test wiring wrongly in a live wire manner and the damage of a relay protection tester and a protection device plug-in are avoided, the personal injury and the equipment damage caused by a wrong short circuit during a short circuit test process are avoided effectively, and the accuracy and the safety during the short circuit test are improved.

A radio pager of the present invention displays a number of stored information in an as ascending order or a descending order selected by the user on a rotary switch included in the pager. In addition, the pager allows the user to see and desired information first by rearranging the information in a storage area on the basis of an information number, a confirmation flag, and a content. The user can therefore select personal and shared information stored in the pager by turning the rotary switch in a jog dial fashion in the ascending order or the descending order or even in any desired order. This enhance easy and efficient search and rapid information selection. The user can also input various data management commands into the radio pager via an interface means 20.

The invention discloses an automatic feeding system of a rotary evaporator. The automatic feeding system of the rotary evaporator is characterized by comprising breakers (2), a switch power source (3), a first electromagnetic valve (4), a first liquid level switch (5), a second liquid level switch (6), a first normally open contact (7), a first relay coil (8), a second electromagnetic valve (9), a third liquid level switch (10), a fourth liquid level switch (11), a second normally open contact (12), a second relay coil (13), a rotary switch (14) and a normally closed contact (15). The automatic feeding system is capable of automatically feeding solution to be evaporated and releasing evaporated solvent, feeding and releasing process is effectively controlled, and time and labor cost are saved.

The invention belongs to the technical field of rotary switches, and particularly relates to a rotary switch with an energy storage mechanism. The switch comprises a shell and an operating mechanism arranged in the shell, the operating mechanism can rotate and has a closed state and an open state, the shell is also internally provided with the energy storage mechanism, and the energy storage mechanism has an energy storage state and an energy release state. When the energy storage mechanism is in the energy storage state, the operating mechanism can be rotatably switched between the closed state and the open state, and when the energy storage mechanism is converted from the energy storage state to an energy release state, the energy storage mechanism can drive the operating mechanism in the closed state to disconnect; an energy storage operation transmission assembly is arranged between the operating mechanism and the energy storage mechanism; and when the energy storage mechanism is in the energy release state, the operating mechanism is manually operated and rotated, and the rotation of the operating mechanism drives the energy storage mechanism through the energy storage operation transmission assembly to enable the energy storage mechanism to be switched to the energy storage state. According to the rotary switch with the energy storage mechanism, energy storage can be completed by rotating the operating mechanism, and operation is convenient.
