Micro switch principle

1. micro switch principle - Introduction

Micro switch contact mechanism having a small contact gap and snap-action mechanism, dynamic switching operation using a predetermined power stroke and regulations, with the housing cover, there is a switch whose external drive rod, because of its switch contact spacing relatively small, hence the name micro-switches, also known as sensitive switch. Widely used in electronic equipment, instrumentation, mining, electric power systems, household appliances, electrical equipment, as well as aerospace, aviation, ships, missiles, tanks and other military fields.

2. The principle of micro-switches - Classification

Micro-switch kind of variety, there are hundreds of internal structure, a volume fraction of ordinary type, small, ultra-compact; by protective performance points, there are waterproof, dust-proof, explosion-proof; by breaking in the form of points, single-linked, double, multi-connection type. Currently there is a strong disconnect micro switch; by breaking capacity points, a common type, DC-based, micro-current, large current type. By use of the environment, a common type, high temperature, ultra high temperature ceramic micro switch without auxiliary ships to annex the basic press types, and derive a small line program, accusing him of apps.

3. The micro-switch principle

Micro switches principle: the use of external mechanical force transmission elements by the force on the reed movement, resulting in instantaneous action when the action shifted to the critical point of the reed, reed action to make the end of the movable contact and fixed contacts quickly turn on or disconnected. When the force on the transmission components removed, the action force reeds produce the reverse action, when the drive element reaches the reverse stroke reed movement critical point, instantaneous reverse action. Micro switch contact spacing is small, short stroke action, according to power a small, on-off quickly. Dynamic contact movement speed and movement independent of the speed transmission components.
