Micro Switch

Micro switches, also known as snap switches, are operated by using spring-loaded levers to open and close the two internal coordinates inside the device. Micro switches are inexpensive parts that can function for a very long time. And some of the parts can withstand more than 10 million cycles before they break down. The switches are used in a variety of different applications, but their main characteristics being easily actuated and incredibly durable make them common in consumer devices, industrial applications, and other uses where they endure many cycles over their lifespan.


How does the micro switch work?

The power supply is usually connected to a common terminal, which leads to the switch and supplies power to the spring. Because the spring contacts the normally closed pin, the power supply is sent out here which is called a stationary state. Once the robotic arm moves, the power is transferred to the regular budget.


Where can you find them?

These are small devices, usually only designed to carry low current and low voltage. These switches are very safe because they are reliable, cheap, and can be circuited when needed, thereby preventing someone from opening: the machine or closing the door, so safety devices are often used.


Micro switch series standard miniature basic switches are precision snap-action mechanisms enclosed in accurately molded plastic cases. Besides, these switches are designed for high precision, presence/absence detection, where physical contact with an object is permissible and in simple on-off actions.


Daier’s micro switches fill many roles in customers’ applications. Also, it includes presence, absence, positioning as well as inspection, recognition, condition measurement, etc. From sealed switches used in high-temperature aerospace applications to large cable-pull switches that ensure safety on conveyors, Daier is the right switch!


Daier provides sealed miniature and ultra-miniature micro switches that comply with industry standards and RoHS regulations.These switches are suitable for application flexibility. Furthermore, Daire’s certifications include CE, CQC, & TUV. Normally, the annual production of micro switch in Daier is very huge, we can meet all of the requirements of each customer.


With years of design and manufacturing experience, Daier Electron is the market leader in the micro switch. We have 20 years of design experience, we are your best choice.

Ten forms of actuator, no lever, short lever, long lever, medium lever, arc lever, roller lever, long roller, big arc lever, long big arc lever, and arc roller lever. Eight options of terminal, quick-connect terminal, solder/quick-connect terminal#187 (t=0.8mm), 187quick-connect terminal (=0.5mm), left side PCB terminal, screw terminal, solder terminal, right side PCB terminal, not standard terminal.

Waterproof Micro Switch

Daier's waterproof micro switches use RoHS materials and have no health hazards. Switches are available with protection levels up to IP67, electrical ratings from low levels up to 15 amps, and a wide operating force range of 50gf~400gf. Waterproof micro switches have excellent performance, high reliability, and long service life. Many applications include automotive applications, arcade game machines, medical devices, security systems, etc.

Limit Switch

A limit switch is a common low-current main electric appliance. Such switches are often used to limit the position or travel of mechanical movement. It can make the moving machine stop, reverse, variable speed, or automatic round-trip motion according to a certain position or stroke.   Limit switches are widely applied in various machine tools and hoisting machines to control their strokes and provide terminal limit protection. In the control circuit of the elevator, the travel switch can control the opening and closing speed of the car door, the opening and closing limit of the automatic door, and the upper and lower limit protection of the car.

Hook Switch

An electronic hook switch (EHS) is a device which electronically connects a wireless headset and phone. An EHS passes predefined signalling. Either bluetooth headset or DECT headset can be used. Users can handle calls with the headset only, freeing them from remaining next to the phone. Switching from handset to headset is typically accomplished by pushing a specific button. This cable eliminates the need for an HL10 handset lifter. This cable works with Cisco desk phones and may work with additional manufacturers
