What is ON/OFF Micro Switch

The ON/OFF micro switch is a simple micro switch that uses an internal spring and lever mechanism to quickly start and break the circuit. When external force is applied to the drive rod, the internal structure will produce an instantaneous action, causing the switch to quickly switch from the off state to the on state, or reverse switching.

ON state:

When the external mechanical force is triggered, the internal contacts of the switch are quickly closed, the current path is established, and the device is turned on or the signal input action is completed, with good response speed and feedback clarity.

OFF state :

When the pressure is released or the lever is reset, the internal spring returns to its initial shape, the contacts are separated, the circuit is disconnected, and a safe shutdown or control termination is achieved.

The core advantages of this micro-movement structure are long action life, fast response speed, and high contact stability. Some models also have dustproof, waterproof, anti-oil and other functional extensions, making them highly adaptable in industrial control, transportation equipment, outdoor devices and other fields. The compact and powerful ON/OFF micro switch is an indispensable key component of modern control systems.

FAQ

Why must industrial/automotive systems use waterproof micro ON/OFF switches?

Waterproof switches can avoid water short circuits and rust, ensure long-term stable operation of the system in high humidity, salt spray and other environments, and reduce after-sales risks.

Is it safe if the waterproof level reaches IP67?

IP67 only represents static water pressure testing. In actual applications, many factors such as seal aging, vibration and water ingress prevention, and chemical corrosion resistance must be considered.

What problems will arise if the specifications of the ON/OFF micro switch are selected incorrectly?

Wrong selection can easily lead to malfunction or contact oxidation. For example, SPST/SPDT, trigger force, contact material, etc. must accurately match project requirements.

Why do many projects have problems after batch production?

Qualified samples do not mean stable mass production. Unionwell ensures consistency of each batch and avoids performance deviation through automated assembly and full inspection.

What customized services can Unionwell support?

We provide more than 10 customized services such as current and voltage, terminal harness, cap color logo, certification assistance, etc. to meet the diverse needs of OEM customers.

Is the process efficient for new customers from design to delivery?

We support drawing within 3 days, proofing within 5 days, and mass production within 15 days. The delivery is efficient and transparent, and we have served many European and American equipment manufacturers for continuous return orders.
