Choosing a microswitch is like choosing clothes at the market—you have to find the one that fits you best. Choosing the right one is a joy, but if you’re lucky, you’ll have a lot of trouble. Let’s discuss the details to consider when choosing a switch.
Rated Parameters
The voltage and current values require careful consideration. For example, if they are too low, the switch will overheat, or even burn out. If they are too high, you’ll spend more money and may not be compatible with the equipment, causing integration problems. So, when choosing a switch, be mindful of the specifications to avoid overdoing it or making a fool of yourself by trying to pull a heavy cart.
Operating Force
The force required to press a switch is like pressing an elevator button: too light and you’ll easily make the wrong move; too heavy and you’ll feel tired. Choosing the right operating force depends on the specific situation. For example, if it’s for the elderly or children, choose a lightweight one; if it’s for industrial use, choose a strong and durable one.
Lifespan
Switches must be durable. If they aren’t, they’ll need to be replaced soon, which is both expensive and frustrating. Generally, the durability of a microswitch refers to the number of times it can function properly. When choosing a microswitch, consider the frequency of use. If the device is used frequently, choose a durable switch to avoid frequent replacements.
Installation Method
There are many installation methods, such as plug-in and stick-on. Plugging in is simple, but takes up space; stick-on options, while smaller, are more laborious. Choosing which one to choose depends on the design and production of the device. If it’s mass-produced, a stick-on option is probably more suitable; if it’s produced in small batches or hand-assembled, a plug-in option is definitely more convenient.
Environmental Adaptability
The environment significantly impacts a small switch. For humid environments, choose a waterproof one; for hot environments, choose a heat-resistant one. If this rule is not followed, the small switch will only last a few days in the harsh environment before it breaks down, and the equipment will also suffer.
