Precautions for selecting microswitches

In military and civilian wireless equipment and automatic control equipment in production processes, various types of microswitches and other connectors are often needed to achieve manual or automatic circuit switching, connection or disconnection control, and to replace various complex circuits with a few circuits. With the development of science and technology, as well as the different requirements for installation, operation control, aesthetics, and reliable performance, the strict requirements for military equipment have led to an increasing variety of switch specifications.

When selecting a switch, pay attention to the following points:

a. For the parts where the circuit is often connected or disconnected, a circuit breaker type switch can be selected, such as a button switch, fluctuation switch, or button switch.

b. Equipment that requires control in a short period of time, such as oil compressors and machine tools, can use micro switches, automatic reset button switches, button type conversion switches, etc.

c. As a type of frequency conversion and control range in instruments and meters for multi speed transceivers, multi speed button switches, straight key switches (piano key switches), rotary switches (including band switches, brush switches, cam switches), and sliding switches should be selected.

d. Nighttime operation is required, especially on panels used in the field and battlefield, button switches with illuminated indicator lights, I49 1U686K004AT bright colored fluctuation switches, etc. should be used.

e. To prevent accidental movement caused by collision with clothing or other objects, lock handle type button switches, rotary switches, and button switches with protection should be used.

f. Equipment used for long-term unattended operation should use micro switches.

g. For the connection and conversion of weak signals, the switch used at a low level should be selected. There are low voltage switches in various types of switches, and if a switch with a general load is selected, it may cause unreliable contact.

h. Equipment working in the field and with harsh weather conditions may be exposed to rain, sunlight, and dust. Therefore, switches that can be used under the corresponding components should be selected, such as environmentally sealed, panel sealed, elbow sealed, or waterproof switches.

Specification for the use of microswitches

Micro switches are mainly used for mechanical control, so the requirements for the type, stroke, and action force of switch actuating components should be stricter. When selecting microswitches, several points should be noted.

1. The switching action characteristics will change with the increase of switching times during the load on/off process, and the magnitude of this change is called the stability of the action characteristics.

2. Users are not allowed to add other transmission mechanisms to the micro switch during use.

3. The installation of the switch must be carried out according to the dimensions specified in the product manual or standard.

4. Users should not install additional devices or modify switches separately, otherwise it will affect the switching characteristics.
