Abstract

The invention provides a circuit on-off testing device applied to the technical field of circuit on-off device. A test thin rod I (1) of the circuit on-off testing device is connected with the positive electrode of a battery (4) through a connection wire I (3). A test thin rod II (2) is connected with the negative electrode of the battery (4) through a connection wire II (5). Both of the test thinrod I (1) and the test thin rod II (2) have a structure made of tin-coated copper bar having a pointed end. The circuit on-off testing device is simple in structure and can test the on-off of a wirecircuit conveniently and quickly. At the same time, the circuit on-off testing device can suit a characteristic of narrow space of the wire circuit and realizes single-hand operation, so that test convenience is improved.

Description

technical field [0001] The invention belongs to the technical field of line on-off equipment, and more specifically relates to a line on-off testing device. Background technique [0002] A multimeter is often used to test the continuity of the wiring harness line. However, because the multimeter has the characteristics of relatively many functions, relatively large volume and easy to break, it makes it only used in the production of wiring harness lines and other functions. In terms of field, it is not an optimal choice. The tip of a traditional multimeter is relatively thick for aircraft and other high-precision avionics manufacturing fields, making it difficult to insert it into smaller holes. In the field of maintenance, because the working environment is often narrow and dark, and requires two-handed operation; carrying a flashlight at this time will increase the difficulty of the work, or reduce the quality of work, or increase the manpower and reduce efficiency. Con...
